The plants in this compartment will begin to assume a different aspect, and air must be admitted every day if practicable, giving large portions in sunshine by the sashes regularly over all the house, opening those of the front a little, and likewise the doors in fine mild days. To perform this judiciously, give a little about eight or nine o'clock, more at ten, and the whole from eleven till twelve o'clock, shutting again by degrees.

Fire heat will now be dispensed with, but in frosty nights have the shutters on about sundown. The sun is now powerful, and the house can be early shut up in the afternoon, and will gain as much natural heat as will keep up the required temperature, viz. 36° to 40°. Perhaps there may be uncommonly cold weather; at such times be attentive to ward off danger by applying artificial heat.

OF WATERING.

Look over the pots and tubs at least every alternate day, to see where water is wanted. In watering, too much caution cannot be used, especially during winter and the commencement of spring. It was observed last month what would be the effect of too much water. It may be remarked, that if the exterior of the pot is very damp, the soil inside is too wet, and in that state is uncongenial to vegetation, which now begins to start, and ought by all possible means to be encouraged. People may be frequently observed watering all plants indiscriminately, not taking the trouble to look into or feel the state of the soil in the pots or tubs, and by going over them three or four times in this manner will be sufficient to put the plants in such a state, that they will not be recruited for some months. Hence the reason of so many sickly plants.

CamÉllias, where there are collections, will continue to flower. Treat them according to the directions given last month.

OF ORANGES, LEMONS, &c.

Be sure they are not too wet, as too much humidity as well as aridity causes their foliage to have a yellow appearance, with this difference, that in the former case the foliage is the same to the touch as when green; but in the latter, it is soft and dry. We have observed trees in tubs and half barrels, with holes all round their sides. This is a ludicrous idea, having the appearance of keeping the water from reaching the bottom of the tub or barrel. For the best kind of tub for large trees, see August under this head. If any of the trees have stunted, straggling, or irregular heads, about the end of this month, or beginning of next, head or cut them down to the shape desired. The old wood will push fresh shoots. You may cut close, or shorten less or more, according as you desire young shoots to arise; at the same time observe that you do not cut below the graft or inoculation. Trees thus headed down should be kept until May, and then planted in the garden, (see May,) or if that cannot be done, turn it out, and reduce the ball of earth by probing with a pointed stick all round the sides and bottom of the ball, cutting off any very matted roots. If any of the roots are decayed, cut them into the sound wood. By being thus reduced, it will go into the same pot or tub if not a less one. Having a good supply of fresh earth ready, put a few inches in the bottom of the pot or tub, place the tree therein, and fill all round, at the same time pressing it down with the hand or a stick. Give very little water until there are signs of vegetation.

MYRTLES, OLEANDERS, &c.

These, with similar exotics, may be treated as above. If any of them have been infected with the scaly insect, after heading down, &c. scrub the remaining stems with a strong decoction of tobacco, heated to about 100°. Afterwards clean with soap and water.

GERANIUMS.

These will be growing freely. Keep them in airy situations, so that they may not grow too weak, and flower imperfect. To flower these plants strong, and of good colour, they must not be too crowded together, neither far from the light, and have plenty of air admitted to them, when the weather is favourable. Keep them free from the Green-fly by fumigating frequently.

HERBACEOUS PLANTS.

Plants of this character will, by the first of the month, begin to grow. The best time to divide and fresh pot them is when the young shoots are about one inch above ground. See under the head Shifting in this month.

OF CAPE BULBS, &c.

Cape Bulbs, such as LachenÀlias, Oxalis, Ixias, GladÌolus, WatsÒnias, BabiÀnas, &c. will in many of the species be showing flower. Keep all of them near the glass, to prevent them from being weak and unsightly.

Hyacinths, Tulips, Narcissus, &c. Those that have been kept in the Green-house during winter will be in great perfection. Have all the flower stems tied up neatly to small stakes, (which, if painted green, will look much better,) and keep them from the direct rays of the sun. In the front of the house perhaps will be the best situation. They must be freely watered while in flower. Where there is convenience, it will be essential to keep the pots in saucers containing water; it will strengthen both stems and flowers, and likewise preserve them longer in perfection. Those that are blooming should be put aside, and watered sparingly, until the foliage begins to decay, when the pots may be laid on their side to ripen the bulbs.

REPOTTING.

If you have any of the following plants that you are desirous of encouraging, they should be repotted this or next month at the latest. Large plants will not require it, if they were done in August. Pots one size larger than those that they are in, are sufficient. Acacias and MimÒsas being now united into one genus, there are above two hundred species. About one hundred and thirty belong to the Green-house. Amongst such a beautiful family, both for elegance of flower and beauty of foliage, it will be difficult to specify the most handsome and desirable for this department. A. mÓllis, A. glaucÉscens, A. verticilÀta, A. florabÚnda, A. diffÙsa, A. armÀta, A. verniciflÙa, A. decÚrrens, A. armÀta—weeping variety, A. pÚbescens, A. leucolÒbia, A. decÍpiens, A. fragrÀns, A. pulchÉlla, A. lophÁntha, A. myrtifÒlia, &c. These will afford a great variety of foliage, and are very desirable, flowering principally in winter, or early in spring. The flowers of those belonging to the Green-house are of a yellow or straw colour; the most of those that are red or purple, with the celebrated medicinal species, belong to the Hot-house, for which see May. There are some of the species very subject to the white scaly insect, which must be attended to, that they may not get to any extent.

AgapÁnthus, three species. They are all blue flowers. A. umbellÀtus is very celebrated, and well known in the collections of the country. There is a variegated variety of it highly desirable, the foliage being white striped, and frequently the flower stem and the flower are as good as the species. They have very strong roots, and require plenty of freedom. Plants are always large before they flower, and when the pots, by frequent shifting, become inconvenient, the plant should be divested of all the earth, and, if too large, divide it, cutting off the strongest of the fibres; then they will admit of being put into smaller pots. If the above operation is performed in August or September, it will not retard their flowering, which, when well grown, is very handsome, the flower stem arising about three feet, and crowned with twenty or thirty brilliant blue blossoms, continuing to bloom successively.

AlonsÒas, five species, all soft wooded, small, shrubby plants, with scarlet flowers. A. incisifÒlia is known amongst us under the name of HemÍmeris urticifÓlia, and A. lineÀris as H. lineÀris. If well treated, they form very handsome plants, and flower freely. They will not bear strong fumigation; and, when the house is under that operation, they must be put on the floor of the Green-house, where they will not be so much affected. They flower from May to August.

AÙcuba japÓnica is the only species. The flowers are small and almost insignificant, colour purple; but the foliage is a desirable object, being yellow spotted, or blotched. It is tolerably hardy, and withstands our winters. It prefers shade, and, if the situation was such when planted out, it would grow more freely. The hot rays of the sun are very prejudicial to its growth. It is an evergreen shrub, and very desirable.

Anagyris, three species, evergreen, pea flowered shrubs, flowers yellow, nothing very attractive in either of the species. A. foetida is found in many collections, and we have no doubt but it may prove, in this country, a hardy shrub.

AzÀleas, seven of the China species, which are those we shall enumerate here. The one that has been longest known in the collections of this country is A. Índica, a most splendid shrub, with scarlet cup flowers and dark spots. A. Índica Àlba, flowers of the purest white, and rather larger than the former. A. Índica purpÙrea pleno, double purple. This variety is not so fine as any of the others. Properly it is not purple, or, if it may be termed so, the colour is very light; the flower irregular. A. Índica phoenÍcea is magnificent. The colour is darker, and the flower larger than A. Índica, and a free grower. A. sinÉnse, flowers large, yellow. The wood is much stronger than any of those previously mentioned. It bears a very high character in Europe. It has not yet flowered in our collection, but appears as if it would in the ensuing season (1832). All the above ought to have a situation in every Green-house. They flower from March until May. There are two other varieties which have not come under our observation. Do not shift or repot them, if they are in flower, until the flowering is over. The pots must be well drained; and the plants require a shaded situation. If they are properly treated, they will be completely covered with their showy flowers every year.

AÒtus, two species, both fine leguminose plants. A. villÒsa, is a native of Van Dieman's Land; and A. virgÀta, is from New Holland. The former is preferable. Both have yellow flowers, and are small evergreen shrubs.

AndersÓnia sprengelioÍdes, is the only species, and closely allied to EpÁcris, flowers small, and of a pale yellow colour. Drain the pots well; flowers from March to August.

Arbutus, eight exotic species, and six varieties. They are generally hardy in England; but we question if they stand out in the middle states. A. unÌdo rÙbra has the finest crimson flowers; A. serratifÓlia, the largest panicles; and A. AndrÁchne, the finest foliage. They flower in nodding panicles; the flowers are principally white, tinged with green, and wax-like. They bear a pretty fruit similar to a strawberry; hence it is called strawberry tree, and the fruit will remain on the bush a long time. They are very fine evergreens, and if any of them become acclimated, they will be a great acquisition to our gardens.

BÁnksias. There are about thirty-two species, all curious in flower, and handsome and various in foliage; flowers in large heads and cone-shaped anthers, mostly green, and continue a considerable time in flower; produces a cone in shape of a pine, but not imbricate. The substance is as hard as bone, and contains many seeds. A cone of B. grÁndis in our possession weighs one pound twelve ounces, and contains about 107 seeds. Those most admired for the foliage are B. dentata, B. Æmula, B. serrÀta, B. latifÒlia, B. grÁndis, which is the largest. B. speciÒsa has the longest foliage. B. CunninghÁmii, B. spinulÒsa, B. palludÒsa, and B. rÈpens, these will afford a good variety. B. verticillÀta is entirely different in appearance from the others.

They should be well drained, and placed in an airy part of the Green-house. Great care should be taken that they do not get too dry, for they seldom recover if allowed to flag for want of water. This genus is named in honour of Sir Joseph Banks, a distinguished promoter of the study of natural history.

BignÒnias. Those of this genus belonging to the Green-house have been divided to TecÒma, and there are only three for this department. T. austrÀlis known as B. PandÒrÆ; T. grandiflÒra, known as B. grandiflÒra, and has large and magnificent clusters of orange-coloured flowers, flowering from May to October.

TecÒma capÉnsis is a very pretty climbing shrub, a free grower, and flowers abundantly; flowers in dense panicles, colour orange and red, continues for several weeks in succession from April to August, greatly esteemed in Europe where it is known; being now in a few of our collections, will soon be generally admired.

BlÈtia hyacinthÌna is the only species belonging to the Green-house, once known as CymbÍdium hyacinthÌnum. It is herbaceous, and when it begins to grow divide the root, putting the best into five inch pots. The spike of flowers are hyacinth-like, and of a beautiful purple, flowering from April to July.

BorÒnia is a beautiful genus of New Holland plants, contains about nine species; most of them have been universally admired; the flowers are star-like, and rose-coloured, and some of them sweet-scented. B. pinnÀta grows and flowers freely. B. serrulÀta, foliage serrated and very crowded, bearing the flowers on the extremity of the shoot. B. alÀta has a fine appearance, and grows handsomely. The foliage is winged and pinnate, of a hardy nature, and easy culture, flowers freely. They are in flower about April and May, and continue a considerable time; are subject to mildew if not frequently syringed; drain the pots well.

BouvÁrdias, two species. B. triphylla is well known amongst us, has brilliant scarlet flowers, and when well grown, will flower beautifully from May till September. To keep the plants, they should be frequently renewed; otherwise they are liable to grow straggling, and become subject to the small white scaly insect. B. JacquÌnÆ we suspect has got confounded with the former, being very little different, except the foliage, which is more pointed. They flower from the young wood, and often throw their foliage in winter.

BrachysÈmas, two species, both evergreen climbers. B. latifÒlium has the best foliage, and large purple leguminose flowers. B. undulÀtum, flowers yellow, and more plentiful than the former, continuing in long successions. The pots require to be well drained; very few plants of either in the country.

BurchÉllias, two species. B. capÉnsis is a beautiful dwarf evergreen shrub, with tubular scarlet flowers in large terminate clusters; when well treated, grows and flowers freely, and highly deserving of attention. B. parviflÒra differs from the above in the flowers being smaller and paler, and the foliage more pointed.

BeaufÓrtias, only two species. B. decussÀta is splendid; the flowers come out of the wood with stamens in fine parcels, colour bright scarlet, foliage decussate, oval, and many-nerved, bloom persistent, and much esteemed. B. spÁrsa, in flower similar to the other, colour light pink, foliage scattered, both easy of culture, and flower abundantly.

BrÙnias, about ten species, have heath-like foliage, very fine, generally, on close observation, found to be three cornered. The flowers are white and globular, the plants when young are very handsome; the finest are B. nodiflÒra, B. lanuginÓsa, B. comÒsa, B. abrotanoÍdes, and B. formÒsa. They require an airy situation, and in summer to be protected from the powerful rays of the sun. Drain the pots well.

BÓsea yervamÓra, Golden rod tree, leaves large, alternate, ovate, acute, with purple veins and nerves, flowers brown, in axillary dense panicles, grows strong and freely.

BÆckias, above twelve species, of heath-like appearance, and except for variety, are not otherwise desirable. B. camphorÀta is camphor-scented; B. pulchÉlla is very neat; and B. virgÀta flowers freely. Pots should be well drained. The flowers of all the genus are white.

BillardiÉras, about five species, are desirable as climbers, being of rapid growth, and abundant in flower. B. longiflÒra, fruits freely, and has fine blue berries which look handsome. B. mutÁbilis is changeable from purple to scarlet. The fruit of B. scÀndens is covered with down, flowers straw coloured. B. fusifÓrmis differs in colour from the others, the flowers being blue. They require to be well drained.

CalceolÀrias, about fourteen species, besides many hybrid varieties. C. angustifÒlia, and C. integrifÒlia are the best of the shrubby species. C. plantagÍnea, C. corymbÓsa, C. purpÙrea, and C. hopiÁna, and of the hybrid varieties, C. micÀns and C. hybrÌda are very fine; but we understand they are numerous, and some of them very splendid.

To grow any of these properly, they should be divided a few weeks after they begin to grow; put them in small pots at first, and enlarge them gradually. Where there is a hot-house, after dividing them, it will greatly promote their growth to keep them in it a few weeks near the glass, until the weather gets mild, when they may be removed to the Green-house. The flowers are principally yellow. C. FothergÍllii, purpÙrea, and archnoidea are purple; the hybrids are spotted with red and brown, and some of them streaked many colours. They continue a long time in flower.

CalothÁmnus, four species. This genus is named in allusion to the splendid appearance of the branches, covered with scarlet flowers of curious construction, which come out of the old wood. All the species are of easy culture, and very like dwarf pines. C. quadrÍffida has the largest flowers; C. clavÁta the most abundant. They are all evergreens, and flower from April to November.

CamÉllias. There are about nine species, celebrated over the known world as furnishing the domestic drug called tea, in universal use, besides many flowering trees and shrubs as universally admired. Oil may be expressed from the seeds of all the species, and used as that of hemp and poppy in cookery. C. vÍridis and C. bohÈa are said to be the species which supply the tea. Some have asserted that there is only one shrub used, but by examination it may be easily perceived that there are leaves of various shape and texture, some of them similar to C. sasanqua. Dr. Abel gives an explicit detail of the growing and manufacturing process of tea, from which, in compliment to our fair patrons, we give a few extracts:

"The tea districts of China extend from the twenty-seventh to the thirty-first degree of north latitude. It seems to succeed best on the sides of mountains. The soils from which I collected the best specimens consisted chiefly of sand-stone, schistus, or granite. The plants are raised from seeds sown where they are to remain. Three or more are dropped into a hole four or five inches deep; these come up without further trouble, and require little culture, except that of removing weeds, till the plants are three years old. The more careful stir the soil, and some manure it, but the latter practice is seldom adopted. The third year the leaves are gathered, at three successive gatherings, in February, April and June, and so on until the bushes become stunted or slow in their growth, which generally happens in from six to ten years. They are then cut in to encourage the production of fresh roots.

"The gathering of the leaves is performed with care and selection. The leaves are plucked off one by one: at the first gathering only the unexpanded and tender are taken; at the second those that are full grown; and at the third the coarsest. The first forms what is called in Europe imperial tea; but as to the other names by which tea is known, the Chinese know nothing; and the compounds and names are supposed to be made and given by the merchants at Canton, who, from the great number of varieties brought to them, have an ample opportunity of doing so. Formerly it was thought that green tea was gathered exclusively from C. vÍridis; but that is now doubtful, though it is certain that there is what is called the green tea district and black tea district; and the varieties grown in the one district differ from those of the other. I was told by competent persons that either of the two plants will afford the black or green tea of the shops, but that the broad thin-leaved plant (C. vÍridis) is preferred for making the green tea.

"The tea leaves being gathered, are cured in houses which contain from five to twenty small furnaces, about three feet high each, having at top a large flat iron pan. There is also a long low table covered with mats, on which the leaves are laid, and rolled by workmen, who sit round it: the iron pan being heated to a certain degree by a little fire made in the furnace underneath, a few pounds of the fresh-gathered leaves are put upon the pan; the fresh and juicy leaves crack when they touch the pan, and it is the business of the operator to shift them as quickly as possible, with his bare hands, till they cannot be easily endured. At this instant he takes off the leaves with a kind of shovel resembling a fan, and pours them on the mats before the rollers, who, taking small quantities at a time, roll them in the palm of their hands in one direction, while others are fanning them, that they may cool the more speedily, and retain their curl the longer. This process is repeated two or three times, or oftener, before the tea is put into the stores, in order that all the moisture of the leaves may be thoroughly dissipated, and their curl more completely preserved. On every repetition the pan is less heated, and the operation performed more closely and cautiously. The tea is then separated into the different kinds, and deposited in the store for domestic use or exportation.

"The different sorts of black and green arise, not merely from soil, situation, or the age of the leaf; but after winnowing the tea, the leaves are taken up in succession as they fall; those nearest the machine being the heaviest, are the gunpowder tea; the light dust the worst, being chiefly used by the lower classes. That which is brought down to Canton, then undergoes a second roasting, winnowing, packing, &c. and many hundred women are employed for these purposes." KÆmpfer asserts that a species of CamÉllia as well as Olea frÀgrans is used to give it a high flavour.

C. oleÍferia is cultivated principally in China for the oil which is expressed from its seeds, which is much used in the domestic cookery of the country; flower single white.

C. SesÁnqua, Lady Banks's. The foliage of this species is very small, and paler, and the green not so fine, as any of the others. It seeds freely, and is often used as the female parent in producing new varieties; flowers small white and single, with many anthers. There are a Semi-double, and Double variety of it of the same colour.

C. maliflÒra is figured in the Botanical Register, under the name of C. SesÁnqua rÓsea. The foliage is about the same shape as C. SesÁnqua, but the appearance and habit of the plant are completely different, growing very freely and quite erect; flowers very abundant. A large plant of it will continue in bloom for the space of three months. The flowers are of about six weeks' duration, colour and shape of Rose de meaux; has been highly esteemed. One plant of it has been sold for one hundred and eighty dollars.

C. KÍssii. We believe it is single white, has not come under our observation, the only species that is a native of Nepaul.

C. reticulÁta was brought from China by Capt. Rawes. The foliage is very characteristic, being rougher than any of the other flowers, about five inches in diameter, brilliant scarlet, and semi-double. It was introduced into Europe in 1822, and is still very scarce. Twenty-five dollars are paid for a small twig of it. From present appearance, it will never be so plenty as many of the others, being tardy of propagation; only a few eyes on the extremity of each shoot make young wood, and if these are cut off, the plant does not seem to push afresh.

C. japÓnica, the original of many splendid varieties, probably to the amount of one hundred. The true one is in very few collections; it is single striped.

C. japÓnica rÙbra is the single red of our collections, and used as stocks to enarch, graft, or inoculate the other varieties upon, being easily struck by cuttings. It seeds very freely, when the stile is impregnated, and the seedlings make the strongest and best stocks.

C. japÓnica Álba, single white. It is mentioned in some of our catalogues, as being very sweet-scented, though not very perceptible to us. The foliage and wood are very strong, being a free seeding variety, consequently particularly desirable, as a stock to grow new varieties from. Its flowers are large and abundant.

C. semidÚplex. This is a flower with two rows of petals. Some good varieties might be got from it, if properly impregnated.

C. rÙbro-plÈno is a strong growing and free-flowering variety. The flowers are large, double red, petals irregular, with the anthers in bunches amongst them; flowers are of long duration and showy.

C. cÁrnea, frequently known as Middlemist's blush. Colour pink, one of the original varieties, and frequently produces seeds; grows freely.

C. myrtifÓlia, known in some collections as involÚta. There are two varieties of it, major and minor; the former is certainly the best, and has a very handsome, large, and regular red flower; the centre frequently is pink and purple; it is much the shape of Double white, only the petals are more cupped. The flower is of considerable duration. It is not properly named. The foliage, though the smallest of the variety, is much larger than that of any of our common myrtles, which might make many mistake its character; and another prominent feature is, the leaves are much recurved and shining.

C. hexangulÁris. The flower is six angled, very compact, and dark red. It is an esteemed variety, and there has unfortunately been another inferior, substituted for it, in some of our collections. The foliage is similar in shape to anemoniflÒra, with the nerves more sunk; the flowers are of an ordinary size.

C. atro-rÙbens, Loddiges' red, is a very fine variety; colour dark red outside, petals large inside, small and irregular, forming a very distinct character; foliage stiff; grows freely and flowers well; and of long duration. We have seen a flower stand fresh on the plant two months; however, that cannot be a rule, as it depends on the situation.

C. anemoniflÒra, or Waratah (from the central petals, having the appearance of the Waratah plant, TelopÌa speciosissima.) This variety is very characteristic, both in flower and foliage. The flower is dark crimson, with five or six regular large outside petals; those of the centre are very small, and neatly plaited, with the stile (female organ) prominent; the foliage is large and oblong, nerves very smooth, and the wood strong, bark light. Had this kind not been found, we would have been deprived of many most splendid varieties, which have originated from it, and we have no doubt they may become as diversified as the roses of the garden. This variety in a collection for that alone is invaluable. It seeds freely, and the pollen of any of the others applied to the style of this, will produce a new variety, which seldom fails of being double, provided the pollen is from a double variety. It must be applied the first day that the flower is expanded, for the flower is only of a few days' duration. Those that are not acquainted with the buds of this CamÉllia, will take them to be dead, because, before expansion, they are very dark brown.

C. dianthiflÒra, or Knight's carnation Waratah, is, when well grown, a very beautiful flower; shape and size same as anemoniflÒra (and a seedling from it by Mr. Knight, King's Road, Chelsea, London,) seemingly the stamens are crowned with small petals, red and white striped, appearing like a fine large carnation. The style appears fertile, and there is no doubt but some splendid varieties may be obtained from it.

C. blÁnda, or blush Waratah, flower in shape similar to anemoniflÒra, rather larger, and of considerable duration.

C. pompÓnia, or Kew blush, flowers very large, white, with a tinge of blush at the bottom of the petals, which has a good effect in setting off the flower. They frequently bloom all blush, which appears rather curious on the same plant; shape one or two rows of guard or outside petals; those of the inside are short, stubby, and generally irregular, continues long in flower, yellow anthers among the short petals, and seeds when the female organ is perfect; foliage narrower than any of the others, a very fast grower, and flowers freely.

C. pÆÒniflora. The foliage, shape, and size of the flower of this, is similar to the last mentioned, colour a rich pink; we have never seen any of them vary from this; and have seen it seed very double.

C. WalbÁnkii, has a very large white irregular flower, by some called poppy-flowered. It is not so pure as the common double white; the anthers show amongst the petals, and the buds before expansion are very round, inclining to flatness; the foliage long and shining. The flowers are of considerable duration. We question with lutea-alba.

C. alba-plÈna, common double white, is admired by the most casual observer, and is generally considered a very superior flower, from the purity of its whiteness, and the abundance of its large flowers, which are thickly and regularly set with round petals. The foliage is large, and the plant grows freely; we have seen one shoot grow two feet in one summer. It was imported into Europe from China, amongst the first of the varieties, about eighty years ago.

C. flavÉscens, Lady Hume's blush, and by some called buff. It is a very double flower, and frequently hexangular; the bottom of the petals are most delicately tinged with blush; on looking into it, it shows more like a blush vapour than nature, and is a great favourite, and deservedly so, with the ladies: flowers and grows freely, foliage rhomboid, elongate, nerves very visible, surface smooth and pale green, distantly serrate.

C. fimbriÀta. The size, shape, and set of the flower same as alba-plena, and the white as pure, with the edges of the petals deeply serrated, or rather fringed; is equally as free in flowering and growing. It is universally admired, and in great demand. Its character is unique, foliage very like alba-plÈno. [See Frontispiece.]

C. imbricÀta, said to be a very double red, with imbricated petals, and very handsome. We have not seen it in flower.

C. variagÀta, is one of the old standard varieties, and very much esteemed. It is striped with red and white; sometimes the ground is red, with white streaks or blotches, and vice versa. The flower when well grown is large, and very abundant; foliage very fine dark green, similar to single white. We have had seed from it. The petals are regular, with the anthers showing amongst them; the flower double, though not so much so as many of the others.

C. crassinÉrvis. We have not the smallest doubt but this is the same as hexangularis, and in confirmation of our opinion, we have lately had the best authority in Europe to that effect.

C. conchiflÒra, shell flowered, double, a very handsome shape, petals round, stiff set, and in the centre quite erect, red with occasional splashes of white.

C. rubricÁulis, Lady Campbell's, very double, colour very rich dark red, with stripes of pure white, beautifully contrasted. The richness of this flower is very striking, and much esteemed; flowers freely.

C. longifÒlia is a single red, the foliage is large, and longer than the generality of them.

C. chandlrerii, or versicolor, colour vivid scarlet with occasional splashes of pure white; the flowers vary, and are of long duration, from six to eight weeks; foliage large and dark glossy green.

C. aitÒnia. This variety is a beautiful specimen of a single flower affording a developement of the organ of fructification; the petals are delicately penciled, and the anthers very bold, colour pink, and the flower very large; grows freely, and, in our opinion, is surpassed by none of the single sorts, for raising fine new varieties, if impregnated with the pollen from double flowers.

C. althÆiflÒra, hollyhock-flowered, is a great beauty, with large double dark red flowers, the veins are very prominent, petals frequently irregular; foliage large, and approaches to the foliage of single red; and is much esteemed.

C. corallÌna, coral-flowered, a very deep scarlet double flower, and bears a high character.

C. insÍgnis, a most splendid double flower, large dull red colour; a very free grower, and highly estimated.

C. anemoneflÒra Álba. Those that have seen the common anemoneflÒra will be disappointed in the appearance of this, not being pure white, neither properly anemone-flowered, though a very good flower, and very distinct from any other; the petals are irregular, anthers abundant, shape resembling pompone; flower not so large.

C. heterophylla. The foliage of this varies very much, a character that none of the others possess; flower double red; and merits a place in collections.

C. WoÓdsii, flower fine double, rose colour; and much has been said in its favour.

C. bÍcolor, a single flower, with a rose ground and white streaks, very pretty, but not so large as many of the single ones.

C. speciosa is a most splendid variety, has been called China striped Waratah. The guard petals are large, round, and bold; colour red with stripes of white; the centre is full of small petals, (like anemoneflÒra,) and spotted; the foliage large and more heart-shaped than any of the others; grows freely, flower persistent, highly esteemed, and considered one of the finest of the coloured CamÉllias.

C. fÚlgens, flower large, and very bright double red, approaching to C. atro-rubens, but more brilliant; foliage a lucid green, very smooth, young wood and wood buds have a red appearance. We have no doubt but it will seed; if so, it will be a first rate breeder.

C. grandiflÓra, a very large single rich red flower, foliage very large; a most splendid single variety, and grows freely. It is recommended to all who wish to improve their collections by raising new varieties.

C. rÓsa sinÉnsis, a very large double flower, colour bright pink, petals long and full, a very distinct variety, with a beautiful dark green shining foliage, grows and flowers freely, and is highly esteemed.

C. intermÉdia, a very large flower, shape of C. pompÒnia, outside petals streaked to the extremity with a rich blush, ground colour pure white, and is in high estimation; grows and flowers freely. It is in very few collections in Europe, and only in three in the United States.

C. rose WaratÁh. The description of this flower is the same as anemoneflÒra, but differs in colour, and being of longer duration, the foliage is uncommonly large.

C. PressÍi's invincible. It has been asserted that it is the same as that known by C. punctata and C. PressÍi. We have not seen it flower, but have seen a drawing of it, the flower equally as large as double white, and same shape, with the petals as regular; the ground colour brilliant red, and spotted with pure white. It is one of the newest varieties, and much valued for its unique beauty; hence called Invincible; foliage large.

C. Rose MundiÍ, is like the garden rose of that name; a large flower, ground colour pink streaked with white.

C. compÀcta is a new double white, petals and flower not so large as the common, but more compact, and is considered a very fine variety.

C. gloriÒsa, is said to be a fine dark double red.

C. RÓssii, is said to be a fine rich double scarlet.

CallicÒma serratifÒlia, the only species and remarkable for tufted yellow heads of flowers, which come out at the axils, and continue from May to July. The foliage is ovate lanceolate, deeply serrated, and opposite.

CarmichÆlia austrÀlis, the only species, has very curious foliage, which the lilac leguminose flowers come out off, and continue from April to June.

CunÒnia capÉnsis, the only species, and a handsome shrub, with large pinnated shining leaves, beautifully contrasted by numerous dense elongated branches of small white flowers, and twigs of a red colour, having the habit of a tropical more than a Cape of Good Hope plant.

ClÉthra arbÓrea, and C. arbÓrea variagÀta, are both fine shrubs; the latter is preferable; leaves are oblong, accuminate, and serrated with a gold edge; flowers white, downy, in large branching racemose spikes, and sweet-scented; grows freely.

CotoneÁsters. Two of this genus are deserving a situation in the Green-house, C. denticulÀta, and C. microphylla; the last is a native of the mountainous districts of Nepaul, and may prove hardy; the flowers are white, small, and solitary, but in the fall it is covered with pretty red berries, and then looks beautiful; culture very easy; will grow in any situation.

CrÒwea solÍgna, is amongst one of the finest and easiest cultivated plants of New South Wales. It flowers at the axils of the leaves, colour pink, with five petals, connected by entangled hairs; in flower from April to December, and frequently through the winter; foliage lanceolate, and a fine green. The plant grows neat, and requires an airy situation; drain the pots well.

ChorizÈmas, about six species, foliage very like some varieties of the Holly; flowers small and papilionaceous; colour red and yellow; though small, they are very neat. C. nÀna and C. ilicifÒlia are amongst the best; if grown from seed, they will flower freely the second year; drain the pots well.

CinerÀrias, Cape aster, about twelve belong to the Green-house. They are herbaceous, or half shrubby, soft wooded plants. C. speciÒsa, C. amelloÍdes, (now called AgathÆa cÆlÉstus,) C. purpÙrea, and C. lanÀta, are among the finest; flowers blue or yellow; the latter is considered the handsomest of the genus. The exterior petals are bright purple, and the interior ones white, and with A. cÆlÉstus, flowers most of the year; flowers syngenesious and star-like. The herbaceous species must be treated as previously mentioned for that kind of plants.

CÍstus, or Rock rose. There are above thirty species, principally natives of Europe, consequently hardy there, and form a great ornament to their gardens, being very abundant and various in flower; but with us they will not stand the rigour of winter. We have no doubt, however, but, through time, some kinds may be grown that will withstand the greatest cold of the middle states; they are low shrubby plants of easy cultivation. C. ladanÍferus, C. monspeliÉnsis, C. sÁlignus, C. popolifÒlius, and C. undulÀtus, are perhaps the best; the flowers are of short duration, frequently only for one day; but the quantity makes up this deficiency, being constantly in flower in May and June, and sometimes flower again in autumn. C. crÈticus is most productive of the Gum laudanum, which is secreted about its leaves and branches. The flowers are generally five-petaled, and some of them large; centre full of stamens; the foundation of the natural order Cistinea.

ClÉmatis, Virgin's Bower. There are only six of these belonging to this, all climbing plants. C. aristÀta and C. brachiÀta are the best; flowers in racemose clusters, pure white; foliage small; and natives of the Cape of Good Hope. The foliage of C. aristÀta is cordate and blotched.

CobÆa scÁndens, the only species. It is a climber of very rapid growth, has been known to grow above two hundred feet in one summer; large bell-shaped flowers; when they are newly expanded, they are of a pale green colour, and change to dark purple; will grow in the garden during summer, bearing a continual profusion of flowers, but will not stand frost. When this plant becomes too large in the house, do not cut it close to the root, except there is a young shoot arising to carry off the superabundant sap, for the old wood will not push, which will soon cause a mortification.

The best method to adopt in such case is to turn back a shoot, and lay it in the ground to root, when it will become a young plant; which should always be done as soon as it appears unsightly. It does best to be planted in the ground, but will not give any satisfaction as to flowering in a pot. It will flower as an annual if sown in pots this month, and placed in a warm room or hot-bed, and planted into the garden about the end of May.

CoronÍllas, a very few are fine species in the Green-house. C. glaÚca is a celebrated plant amongst us, as a free and early flowering shrub. C. valentÍana and C. viminÁlis are equally so, flower from April to June, colour yellow; papilionaceous flowers in clusters; agree best with shade. In summer they ought to be kept behind a fence, or under a tree, as the sun would destroy them in a few weeks. Drain the pots well.

CorrÉas, five species, all very pretty dwarf shrubs, and flower profusely; foliage ovate, cordate, and either rusty or downy beneath. C. Álba and C. rÚfa have both white flowers a little tubular. C. pulchÉlla is a very handsome erect growing plant, flowers large and tubular, of a deep pink colour, and grows freely: it is thought the finest of the genus. C. speciÒsa has been long admired as a splendid free flowering plant; flowers same shape as C. pulchÉlla, but not so large; colour red and yellowish green. C. virÈns is a very free grower, flowers same shape as the two last, colour entirely green. These three last mentioned are abundant flowerers, having a continued succession from November to June, possessing the valuable requisite of flowering through the winter, and ought to be in every collection. They require an airy situation, and the pots to be well drained. The plants in summer must not be fully exposed to the sun.

CratÀgus. There are none of these belonging to the Green-house; but there is a plant in the collections, known as C. glabra, which is PhotÍnia serrulÀta, a native of China, and is a very handsome plant, has long foliage, deeply serrated, very shining. P. arbutifÒlia, a native of California, and is the finest of the genus; flowers in large dense panicles, foliage larger than the former, and not so deeply serrated; they are both comparatively hardy, and we soon expect to see them acclimated.

CuprÉssus may be desired in collections, as erect and handsome growing evergreen shrubs. C. lusitÁnica, the famed cedar of Goa; C. pÉndula and C. juniperoÍdes are the most desirable; flowers are insignificant, and yellowish; we have no doubt they may prove hardy. C. lusitÁnica is the handsomest tree of the genus. Its abundant, very long dichotomous branchlets, distinguish it from all the evergreens of the conoferious tribe.

CalÁmpelis scÁbra, once EccremocÁrpus scÁber, is a very fine climber, where there is a convenience to plant it in the ground. It will flower profusely from March to November; foliage pinnate, with tendrils; flowers from the axils on young shoots in a kind of racemose, and of a golden colour; grows freely.

CelÁstris, staff-tree, about twenty-five species; of no particular beauty. Some of them have numerous small white flowers, in cymes and panicles; foliage generally ovate, acute, and serrated. C. pyracÁntha, C. cymÓsa, C. multiflÒrus, and C. lÚcidus, are the most conspicuous, and all the genera are of easy culture.

CoÒkia pÚnctata, Wampee-tree of China, named in honour of the celebrated Capt. Cook. The fruit is much esteemed in China, where it grows to about the size of a walnut, in bunches; leaves pinnate, ovate, lanceolate, accuminate; when rubbed, have a strong odour; flower small white in racemose spikes, of slow growth.

C. allistÀchys. There are two of them very handsome large growing shrubs. C. lanceolÀta and C. ovÀta, foliage silky-like, and light coloured; flowers yellow, papilionaceous, and very abundant.

DaviÈsias, above ten species, principally natives of New South Wales, all yellow papilionaceous flowers. D. ulicÌna, D. latifÒlia, D. aciculÀris, and D. inricssÀta, are very fine species, flower and grow freely, and require to be well drained; bloom from April to August.

DiÓsmas. This genus is now very much divided, and only contains about thirteen species: the generas that they have been given to, are AdenÁndra, Barosma, AcmadÈnia, and AgathÓsma. We will enumerate a few of the finest species of each. D. capitÁla, D. oppositifÓlia, D. longifÒlia, D. rÙbra, and D. teretifÒlia, are the most conspicuous, all small white flowers except D. rÙbra; foliage small, and all handsome growing evergreens.

AdenÁndras, eight species. This genus is the most select of those that have been subdivided. A. speciÒsa, A. umbellÀta, A. Álba, A. fragrÀns, and A. uniflÒra, are all splendid flowers: and all white except A. fragrÀns, which is red. Pots must be well drained.

BarÓsmas, above ten species. B. serratifÒlia, B. pulchÈlla, purple, B. foetidÍssima, blush, B. odorÀta, white, and B. dioÍca, pink, are the finest.

AcmadÈnias, five species. A. lavigÀta, A. pÚngens, and A. tetragÒnia, blush, are good species.

AgathÓsmas, above twenty-five species, many of them very celebrated free flowering shrubby plants. A. accuminÀta, A. hybrida, A. ThunbergiÀna, A. imbricÀta, A. prolÍfera, A. pÁtula, and A. pulchÉlla, which is the finest of the genus, the dried leaves of which the Hottentots use as powder to mix with the grease with which they anoint their bodies. Some travellers assert that it gives them so rank an odour, that they sometimes could not bear the smell of those who were their guides. In fact the foliage of all the five last mentioned generas, if rubbed by the hand while on the plant, has a very strong smell, some of them very agreeable, others disagreeable. They are all heath-like and evergreen small neat growing shrubs. They require while growing luxuriantly to have their young shoots topped to make them bushy; drain all the pots well, and keep them in airy situations, and not crowded with other plants, or they will become slender and unsightly.

DryÁndras. This genus is closely allied in character and habits to BÁnksia, and contains above sixteen species. D. nÍvea, has a most beautiful foliage, very long and deeply indented. D.formÒsa, has a scent like the fruit of an Apricot. D. nervÒsa, D. floribÚnda, D. armÀta, D. plumÒsa, D. BaxtÈri, D. nervÒsa, and D. falcÀta, are the most conspicuous, and all highly desirable plants in collections. They are very delicate of importation; flowers are straw and orange coloured and thistlelike. Seeds in small cones. Treat them the same as directed for BÁnksias.

Dillwynias, above twelve species, and plants very little known. D. floribÚnda, D. teretifÒlia, and D. phylicoides, are desirable plants; flowers small, papilionaceous, and colour yellow. They are very liable to suffer from too much wet; while dormant, therefore, the pots must be effectually drained.

DampiÈras, four species. The genus is named in honour of Captain W. Dampier, a famous voyager, has Lobelia-like flowers, either blue or purple. C. purpÙrea, C. undulÀta, and C. strÍcta, are the finest; the two former are shrubby; the latter is herbaceous; they all flower freely.

EdwÁrdsias, about four species, very beautiful foliaged plants and have very curious yellow flowers, but do not flower until the plant becomes large. E. grandiflÒra, E. chrysÒphylla, and E. meirophylla, are the best, and are tolerably hardy, though doubtful of ever being acclimated. The flowers are leguminose, foliage ovate, pinnate, from eight to forty on one footstalk, and appears to be covered with gold dust. The hardier they are grown, the more visible it will appear.

Elichrysums. This genus is now extinct, and two splendid species of it given to others. E. proliferum is now PhÆnÀcoma prolÍfera, and has beautiful purple everlasting rayed flowers, and highly esteemed: the foliage round, ovate, smooth, and closely imbricated. E. spectÁbile is now AphÉlexis hÙmilis, has pine-like foliage, and large light purple flowers and everlasting; care must be taken that they are not over watered; drain the pots well.

EnkiÁnthus, only two species, both very fine. E. quinqueflÒrus has large ovate accuminate foliage, flowers pink, and pendulous; very handsome. E. reticulÁtus, the foliage is netted, and the flowers blush; they are liable when dormant to suffer from wet. Be sure to drain the pots well, and sparing in water while in that state.

EpÁcris, above twelve species, and all very ornamental. E. grandiflÒra has been celebrated ever since it was known; the foliage is small, flat, and accuminate; flowers tubular and pendulous, bright crimson, with a tinge of white, and very abundant, in flower from January to June. E. pulchÉlla is likewise a most beautiful plant; foliage very small and closely set, flowers pure white, and in long spikes, sweet-scented. E. imprÉssa, foliage impressed, and flowers rose-coloured. E. paludÒsa, flowers white, and grows very handsomely. E. purpurÁscens rÙbra is a good variety, with bright red flowers. They are mostly erect growing plants; flower from March till June, and a rough, turfy, sandy soil is found most congenial. They are natives of the mountainous districts of New South Wales. The pots must be well drained; the roots will run with avidity amongst the potshreds.

ErÌcas, heath. There are in cultivation in Europe above five hundred and fifty species and varieties of this magnificent genus. About sixty, years ago it consisted only of a few humble British plants, with the heath of Spain, E. MediterrÀnea, which is at present most common in our collections, though in a few years we may expect to see it supplanted by others more splendid.

In their native countries, they are adapted to a great many useful purposes. In the north of Britain, the poorer inhabitants cover their cabins or huts with heath, and build the walls with alternate layers of it and a kind of cement made with straw and clay. They likewise brew ale, and distil a hot spirit from the tender shoots; and it has been known to be used in dyeing, tanning, and many other useful domestic purposes. Encomium on their beauty is not requisite; they are almost as diversified in colour as colour itself. Many are graceful, and most elegant; hundreds are pretty; a few noble and splendid; others grotesque, curious, and odoriferous. To cultivate and propagate them is one of the most delicate branches of horticulture. Nevertheless, it has been said by a scientific writer, that "those who complain of the difficulty of growing the heath are ignorant people who have never had a heath to grow." The most splendid collection in Europe is under the care of Mr. M'Nab, of the Royal Botanic Garden, Edinburgh, where there are two large houses devoted to their culture; and through the whole year a continued profusion of bloom is kept up. Some of the plants are six feet in diameter, and twelve feet high. The soil used is a coarse sandy peat. Pots drained with potshreds, and pieces of freestone, are put down the sides of the large pots and tubs: where these can be had they are essential to the culture of mountainous plants, preventing them from being saturated with moisture, or from becoming dry, they being retentive of moisture, thus keeping the roots in a medium state; for if once the roots are allowed to get thoroughly dried, no art of the gardener can recover them. This may be the true reason why they are said to be difficult of cultivation.

In the summer season the pots must be kept out of the sun, for in a few hours the pot would become heated, dry the roots, and cause death, or a brownness of foliage which would never again become natural. Too much fire heat will hurt them. They only require to be kept free from frost, need a great deal of air and plenty of light; consequently, should be placed near the glass, that they may have the benefit of all the air that is admitted. Their flowers are as varied in shape as variety or colour, but they all partake of a wax-like nature, and are very persistent. For the finest and most select varieties, see the catalogue at the end of this work.

ErÒdiums, Heron's bill. There are about thirty species, all of a Geranium character, and there are among them some very pretty flowering, soft wooded, shrubby, herbaceous, and annual plants. Only a few of them belong to the Green-house, of which E. incarnÀtum, E. crassifÒlium, and E. laciniÀtum, are the finest; culture similar to GerÀnium. The flowers of these are scarlet, pentapetalous, and veiny.

Eucalyptus, above fifty species of them, and the tallest growing trees of New Holland; foliage very diversified, generally of a hard glaucous texture. From their rapid growth, they soon grow higher than the loftiest house. The most conspicuous are E. cordÀta, E. rostrÀta, E. radiÀta, E. pulvigÉra, E. glÒbifera, E. pulverulÉnta, and E. resÍnefera. In Van Dieman's Land, a manufactory has been established, where a tannin is extracted from many of the species. The last mentioned produces gum, like that which the druggists call Kino. They ought not to be too much fostered, as it would in some degree retard their growth. They are of a very hardy nature. When large, the plants will flower freely, and are similar in flower to Myrtle; many stamina proceeding from a hard nut-like capsule.

EupatÒrium. There is only one species deserving of cultivation in the Green-house; flowers syngenesious, white, and in large flattened panicles; very sweet-scented. The plant, when growing freely, in the beginning of summer, should be topped, which would make it more bushy; if not, it is apt to grow straggling. Known as E. elegÁns, in our collections.

EutÁxia's, two species. E. myrtifÒlia is a most beautiful free-flowering evergreen shrub; foliage small, but very neat; flowers leguminose, small, and very many; colour yellow and red; grows freely. The young plants should be frequently topped, or they will grow naked and unsightly. E. pÙngens, similar to the other except in foliage. They flower from March to June, and ought to have a place in every Green-house. Culture very easy.

EuchÌlus obcordÀtus is the only species: Flowers similar to EutÀxia; foliage almost unique, being inverse, cordate; time of flowering from March to June.

FÚchsias, Ladies' ear drop. About twelve species. Several of them elegant and handsome shrubs. F. virgÁta and F. cÒnica are the most splendid of deciduous Green-house shrubs; the nerves of the leaves and young wood of the former are tinged with purplish red; the large pendant flowers which are produced from the axils of the leaves of the young wood continue during the growing season. F. cÒnica grows strong, foliage green, flowers pendant, corolla more spreading than the other, and when in flower is a complete mass of scarlet blossoms. It flowers all summer. F. coccÍnea is a common and celebrated plant, and deservedly so. F. microphylla is a neat glowing, small flowering species. F. arbÓrea, has very large foliage, and rose coloured flowers; a scarce species, but very desirable. F. grÀcilis and F. thymifÒlia, are both fine; most of the flowers are a bright scarlet, the stamens are encircled with a petal of bright purple, and are of very curious construction; they bear a dark purple berry, and are of the easiest cultivation, but during summer they must be carefully kept in the shade.

GelsÈmium nÌtidum, Carolina jessamine, a most beautiful climbing evergreen, flowering shrub. In the months of April and May, it produces many large yellow trumpet-like blossoms of delicious fragrance. If much fostered in growth, it will not flower so freely.

GnaphÀlium, everlasting. This genus has got all the beautiful Cape species taken out of it, and given to AstÉlma and Helichrysum. Of AstÉlma there are above ten species, most of them very splendid, everlasting flowers. A. exÍmia has brilliant red flowers. A. spirÀlis, A. speciosÍssima, A. frÙticans, and A. imbricÀtum, are all very fine; pots must be well drained.

Helychrysums, above forty species, chiefly belonging to the Green-house, all everlasting flowers. H. grandiflÒrum, H. arbÒreum, H. orientÀle, H. frÀgrans, H. adoratÌssimum, H. frÙticans, and H. fÚlgidum, are all very esteemed species, mostly soft white foliage. The pots should be well drained, and the plants kept in an airy situation, as they suffer from the least damp. If the flowers are cut off before they fade, they will retain for many years all the splendour of their beauty; but if allowed to decay on the plant, they will soon become musty, and all their colour fade.

GompholÒbiums, a genus of very pretty delicate plants, all papilionaceous; flowers generally yellow with a little red; foliage very variable. G. barbÍgerum, G. polimÓrfum, G. latifÒlium, G. grandiflÒrum, and G. venÚstum, are fine, the pots must be well drained, and care taken that they are not over watered; they grow freely.

GenÍstas: a few of these are very pretty free flowering shrubs. G. canariÉnsis, G. tricuspidÁta, G. cuspidÒsa, and G. umbellÀta, are the finest Green-house species. All of them have yellow leguminose flowers in great abundance; leaves small, lanceolate.

GnÍdias, about ten species of pretty Green-house shrubs. G. sÍmplex, G. serÍcea, G. imbÉrbis, and G. pinifÒlia, flower the most freely; flowers straw colour, tubular, and corymbose. G. sÍmplex is sweet-scented, leaves small; the pots must be well drained, and care taken that they do not get either too wet or too dry, for the roots are very delicate. The plants must be kept near the glass, or they will be drawn weak.

GoodÈnia, a genus of about twelve species, with cordate, serate, alternate foliage. G. stellÍgera, and G. suÁveolens are sweet-scented; G. ovÀta and G. grandiflÒra are the best. They are principally small shrubs, with terminale or axillary flowers, and flower during summer.

GortÈria personÀta is the only species that belongs to this genus, and is an annual. There are several plants in our collections known as GortÈrias, but which properly are GazÀnia, of which there are five species. G. rÌngens, when the flowers are fully expanded, (which will only be while exposed to the sun, closing at night, and opening again with the influence of the sun's rays,) is a great beauty. The rays of the flowers are bright orange, and the centre dark purple. G. pavÓnia has handsome foliage; flower similar to G. rÌngens, except the centre of the flower being spotted, and is thought to be the finest, but does not flower so freely. G. heterophylla is of the same character, except the foliage, which is variable, the colour orange and vermilion. They are half shrubby dwarf growing plants, and during the months of July, August, and September, are liable to damp off at the surface of the earth, from the action of heat, and too much water. Pots must be well drained, and the plants kept partially in the shade. Their flowers are syngenesious, and about two inches in diameter.

GrevÍlleas, about thirty species. A few of them very handsome in flower and foliage, among which are G. punÍcea; G. acanthifÒlia, (beautiful foliage); G. concÍnna, very pretty straw and rose-coloured flowers; G. juniperÌna, green and straw-coloured; G. lineÀris, white flowers. The flowers of the whole are curious, though not very attractive. Some carry their flowers in racemose spikes, others on flowering branches, which are recurved; the petals are very small and rugged; the stile longer than the appendage. They grow freely, flower and ripen seeds; all evergreen dwarf shrubs.

HÀkeas, about forty species, not generally so interesting or attractive as the last genus; flowers all white; construction similar to GrevÍllea, but the foliage more varied. H. gibbÒsa, H. nÍtida, H. salÍgna, H. suavÈolens, sweet-scented, H. conculÀta, and H. lambÉrti, are the best, and afford a curious variety of foliage; flower in June. Drain the pots well.

HemerocÁllis, Day Lily. Only H. speciÒsa of this genus belongs to the Green-house; the flower is spacious, and of copper colour. A native of Jamaica. It has not found its way into our collections. It is herbaceous, and while growing requires much water. The plant known with us as H. japÓnica is now FÚnkia Álba, (and justly, for the most superficial observer could have distinguished it as not belonging to HemerocÁllis.) It requires to be much fostered to flower well, and plenty of water. If properly treated, it is a magnificent flower, and continues flowering from July to September. We doubt not it may prove a hardy herbaceous plant, (the same as F. cÆrÙlea,) if protected during the first winter.

HermÁnnias, a genus of about forty species, all natives of the Cape of Good Hope, and not worth cultivating. They have yellow cup-like flowers, and are of the easiest cultivation. Several species are in our collections.

HibbÉrtias, about ten species. Three of them are very fine climbing evergreen shrubs, viz. H. glossulariÆfÒlia; H. dentÀta; H. volÙbilis, if closely approached has a disagreeable smell; H. fasciculÀta, H. salÍgna, and H. pedunculÀta, are evergreen shrubs; they have pure yellow flowers of five petals, blooming from May to September.

HabrÁnthus, about ten species of small South American bulbs, nearly allied to Amaryllis. H. AndersÓnii, H. versÍcolor, and H. robÚsta are the finest; they are in colour yellow, blue, and lilac. We have very little doubt but these bulbs will do to plant out in the garden in April, and be lifted in October. Keep them from frost. Thus treated, they are very desirable bulbs.

HÒveas, about eight species, pretty plants of New South Wales, blue pea-flowering evergreen shrubs; the finest are H. lineÀris, H. rosmarinifÒlia, H. longifÒlia, and H. CÉlsii, which is the most superb, and flowers in abundance. They grow and flower freely; the pots should be drained.

HydrÁngea hortÉnsis is a well known plant, and much esteemed for its great profusion of very elegant, though monstrous, flowers. They are naturally of a rose colour, but under certain circumstances of culture they become blue. If grown in brown loam with a little sand, they will preserve their original colour; but if grown in swamp earth with a little mould of decayed leaves, they will become blue. The swamp earth and vegetable mould being more combined with aluminous salt than brown loam, is the cause of the change; and, when first found out, (which was merely by chance,) was thought a great wonder. It must have a very plentiful supply of water when in flower, which is produced on the shoots of the previous year. They will neither grow nor flower well if they are not kept constantly in the shade. When kept in the sun, the foliage is very brown; and by being neglected in watering, we have seen the flowers completely scourged. Being tolerably hardy, when the winters are mild, by a little protection in the open air, they will flower profusely; the flowers will be very large, and in bloom from June to October. They are deciduous, soft wooded shrubs.

HypÉricums, St. John's wort, about twenty species. A few of them are very showy, and with few exceptions have yellow flowers. H. monÓgynum, H. balearicum, H. floribÚndum, H. canariÉnse, H. ÆgyptÌacum, and H. cochinchinense, which has scarlet flowers, are amongst the best, and all of them flower freely; five petals, filaments many in three or five parcels. They are all of very easy cultivation, and bloom generally from April to September.

Ilex, Holly, of I. aquifÒlium. There are above one hundred species of them in cultivation in Europe, differing in variegation, margin, shape, and size of the leaves; some are only prickly on the margin of the foliage, others prickly over all the surface. In Europe they are all hardy, but with us few or none of the varieties are so. If they become acclimated, they will be a great ornament to our gardens, being all low evergreen shrubs. The most common and conspicuous varieties are the hedgehog, striped hedgehog, white edged, gold edged, and painted; the flowers are white and small, berries yellow or red; they do not agree with exposure to the sun. J. CassÍne and J. vomitÒria have very bitter leaves, and, though natives of Carolina, we have to give them the protection of a Green-house. It is said that at certain seasons of the year the Indians make a strong decoction of the leaves, which makes them vomit freely, and after drinking and vomiting for a few days, they consider themselves sufficiently purified.

IllÍciums, Aniseed-tree, three species. I. floridÀnum, has very sweet-scented, double purple flowers, and the plant grows freely and systematically if properly treated, and deserves the attention of the admirers of flowers. I. parviflÒrum has small yellow flowers; I. anisÀtum is so very like I. parviflÒrum in every respect, as to make us conclude they are the same, were I. anisÁtum not a native of China, and the other two natives of Florida. When the leaves and capsules of either of them are rubbed, they have a very strong smell of anise;—they grow very freely.

IndigÓfera; Indigo-tree, about twenty species, belong to the Green-house, and are chiefly pretty free flowering shrubs. I. denudÀta, I. amÆna, I. austrÀlis, I. angulÀta, I. cÀndicans, and I. filifÒlia, are very fine; flowers papilionaceous, in long panicles; colour various, red, blue, yellow, and pink.

IsopÒgons, about ten species of PrÒtea-like plants, all natives of New Holland. They are very stiff shrubs, with leaves very much divided, and cone-like flowers at the extremity of the shoots. I. formÒsus, I. anemonifÒlius, I. attenuÀtis, and I. polycÉphalis, are the finest; flowers are straw, lilac, white, and yellow coloured; the pots must be well drained, and the plants not over-crowded.

JustÍcias. Only a few of these belong to the Green-house, and are very simple looking flowers. The most beautiful of them belong to the Hot-house. J. nÌgricans, small striped flower; J. orchioÍdes and J. AdhÁtoda, Malanut, are the only ones that are worth observation, and are very easily cultivated. J. AdhÁtoda has good looking foliage, but does not flower until the plant becomes large; colour white and light purple.

JacksÒnias. A genus consisting of five species. The foliage is varied, and all natives of New South Wales. J. scopÀria is similar to a plant in our collections, called VimenÀria denudata. J. hÓrrida, and J. reticulÀta, are the finest; the small flowers come out of the young shoots, are yellow and papilionaceous; the pots should be well drained.

KennÈdias, about nine species, all evergreen climbers, of the easiest culture, and flower abundantly. K. monophylla, blue flowered, and K. rubicÚnda, crimson flowered, are common in our collections. K. prostrÀta, (once Glycine coccÍnea) one-flowered scarlet, and K. coccÍnea, many flowered scarlet, are very pretty. K. ComptoniÀna has splendid purple flowers, and K. inophylla is thought the most superb. It is very rare, and we have not seen it flower. They are large purple. The pots should be well drained; and if the plants are much fostered, they will not flower so well; flowers are either in racemose spikes, or solitary, which is rather too much distinction for the same genus.

LambÉrtias, four species of very fine plants, natives of New Holland. L. formÒsa is the finest of the genus that we have seen; flowers large and of a splendid rose colour. L. echinÀta is said to be finer, but has not flowered in cultivation. L. uniflÒra has single red flowers, and L. inÉrmis orange coloured. They are rare plants in the collections on this side of the Atlantic. Drain the pots well; the foliage is narrow, and of a hard dry nature.

LasiopÈtalums, only two species. There were a few more, but they are now ThomÀsias, plants of no merit whatever, in regard to flower; foliage three lobed, small, rough, and rusty-like. ThomÀsia solanÀcea and T. quereifÒlia, are the best species; foliage of the former is large, cordate, and deep indented; they are all of the easiest culture.

LavÁndulas, Lavender, about seven species belong to the Green-house, and a few of them very pretty soft-wooded, half shrubby plants, and if touched, are highly scented. L. dentÀta has narrow serrated foliage, very neat. L. formÒsa and L. pinnÀta are desirable; blue flowers on a long spike; should be kept near the glass; they are of the easiest culture.

LaÚrus. A few species are Green-house plants. This genus has been divided to CinnamÒmum; still there are a few celebrated plants in the original. L. nÒbilis, sweet bay, though hardy, is kept under protection. It will bear the winter with a little straw covering, notwithstanding there should be a plant kept in the house in case of accident by frost or otherwise; there is a variegated variety of it. L. Índica, royal bay, L. foetens, L. aggregÀta, and L. glÚaca, are favourites. There is a species known in our collections as L. scÁbra. The Camphire tree, known as L. camphÒra, is CinnamÒmum camphÒra; the wood, leaves, and roots of this tree have a very strong odour of camphire. It is obtained by distillation from the roots and small branches, which are cut into chips, and put into a net suspended within an iron pot, the bottom of which is covered with water, having an earthen head fitted in it; heat is then applied, and the steam of the boiling water acting upon the contents of the net, elevates the camphire into the capital, where it concretes on the straws, with which this part of the apparatus is lined. They are all fine evergreens, (which the name denotes,) and easily cultivated,

LÌnums, Flax, two or three species are very fine, and flower freely. L. trigynum has large yellow flowers in clusters, and L. ascyrifÔlium, whose flowers are large, blue, and white, and in long spikes. The shape of them is very like the flower vulgarly called Morning-glory.

LobÈlias. Several of them when well treated, form most magnificent flowering plants; they are principally herbaceous. L. TÙpa has the largest foliage, and fine scarlet flowers. L. speciÔsa, flowers light purple; L. fÚlgens, crimson flowers; L. splÉndens, scarlet flowers. The three last are of the same habit; the colours brilliant; and to grow them well, they should be divided, (if there are several shoots arising,) when they begin to grow, putting them first into four inch pots, and shifting them frequently, having them to flower in those of nine or ten inches, which will be about the end of June, or first of July, and they will continue until October. The pots must be always kept in pans or saucers filled with water; likewise give plenty to the surface of the earth, which is to be done during their time of growth and flowering. If this is attended to, they will produce flower stalks from four to six feet in height, and covered with branches and spikes of flowers from bottom to top. The corolla is pentapetalous, three down and two up; they require a little shade. The genus consists of about eighty species; seventy of them are exotics; many of them natives of the Cape of Good Hope, with little flowers of brilliant colours. L. cÆrÙlea, L. ThunbÉrgii, L. corymbÔsa, L. pyramidÀlis, and L. ilicifÒlia, are very fine species, of weak growth, but flower freely.

LomÀtias, about six species; flowers are white or straw colour, and similar to GrevÍllea, but the foliage more handsome.

LophospÉrmum scÁndens. This is a magnificent new climbing soft wooded shrub, with purple, campanulate flowers, which are produced from the axils on the young wood; they bloom from May to September; leaves large, cordate, and tomentose; grows rapidly, and flowers abundantly.

LachnÆas, about five species, remarkable for their downy heads of white flowers; leaves small, ovate, lanceolate. L. glaÙca, L. conglomerÀta, and L. eriocÉphala, are the best species. The pots must be well drained, and in summer the plants protected from the sun.

LeonÒtis, Lion's-ear, four species. They have very fine scarlet tubular flowers, orifice-toothed. They come out in large whorls, and look elegant; but neither plant nor foliage has an agreeable appearance. They are of the easiest culture. L. intermÉdia, and L. LeonÙrus, are the best flowering species.

LeucospÉrmums, about eighteen species, of Proteacious plants, chiefly low growing, and are mostly downy or hairy; flowers yellow, in terminale heads. L. formÓsum, L. grandiflÒrum, L. tomentÓsum, and L. candicans, rose-scented. These are fine species. For treatment, see PrÒteas.

LipÀrias, about five species, much esteemed for their beauty of foliage; leaves ovate, lanceolate, downy or woolly; flowers yellow, leguminose, and capitate. L. sphÆrica, L. tomentÓsa, L. villÓsa, and L. serÍcea, are the finest. L. vistÌta and L. villÓsa are the same, although put in many catalogues as different species. None of them ought to be much watered over the foliage, as it adheres to the down, and causes the young shoots to damp off. Drain the pots well, and keep the plants in an airy situation.

LysinÈmas, four species, closely allied to EpÁcris. In every respect treatment the same. L. pentapÍtalum, L. conspicum, and L. rÒseum, are the best; the flowers of the two former are white. L. silaifÒlia has leaves bipinnatifid and smooth, segments wedge-shaped and cut. L. dentÀta and L. ilicifÒlia are the finest; the pots should be drained.

LonÍcera japÓnica. There is a plant in our collections known by that name, which is now Nintooa longiflÀra; flowers of a straw colour, but come out white. It has been known to withstand the winter, but does not flower, and is frequently killed entirely.

Lychnis coroÀta, is an esteemed Chinese plant; flowers-in abundance, pentapetalous, large, and a little indented at the edges; colour a red-like orange; flowers terminale and axillary. The roots must be divided every spring, or they will dwindle away to nothing. Perhaps a good method of treatment would be to divide the roots, and plant them in the garden; they would flower well, and could be lifted in the fall, and put under protection. We have no doubt that it may become acclimated. If not done so, plant them in four inch pots, and repot them into those of six inch in May. Do not expose them while in flower to the mid-day sun, for it will deteriorate the fine colour.

LeptospÉrmums, about thirty species, all pretty New Holland evergreen dwarf shrubs, with small white flowers. L. baccÀtum, L. pÉndulum, L. junÍperinum, L. ovÁtum, L. stellÀtum, L. grandiflÓrum, and L. scopÀrium, are the best of the species. The latter was used as tea by Capt. Cook's ship's crew. It is an agreeable bitter, with a pleasant flavour, when fresh. When young plants are growing, they ought to be frequently topped to make them bushy, and kept in an airy situation, or they will be drawn and unsightly. They are of very easy culture.

LeucadÉndrons, Silver tree, above forty species, all natives of Cape of Good Hope. They are evergreens with handsome, silvery-like foliage. L. argentÉum (once PrÒtea argentÉa) is a great beauty; foliage white, lanceolate, and silky. It is a plant that has been long in cultivation, greatly admired, and much sought for, and is the finest of the genus. L. squarrÒsum, L. stellÀtum, (once PrÒtea stellaris) L. tÓrtum, L. servÍceum, L. margÌnÀtum, and L. plumÔsum (once P. parviflÒra) are all fine species. The pots must be well drained, and the plants never over-watered. They are very desirable in collections for their beauty of foliage; flowers similar to PrÒtea.

MagnÒlias. There are four species that require the protection of our Green-houses; all the others are hardy. M. fuscÀta, and M. annonÆfÒlia, are very similar in foliage and flower: the young branches and leaves of M. fuscÀta is covered with a brown, rusty-like down; the other by some is considered merely a variety; flowers small, brown, and very sweet-scented. M. pÙmila is very dwarf growing; leaves large and netted; flowers semi-double, white, pendant, and fragrant. They are natives of China. We have several others from the east, but being deciduous are perfectly hardy. M. odoratÍssima, now TalÀuma CandÓlii, a native of the Island of Java, and said to be very odoriferous, but is very rare even in Europe; said to have a straw coloured flower. M. conspÍcua is desirable to have in the Green-house, if enarched on a stock of M. purpÙrea, which will always keep it dwarf, and it will flower magnificently in February and March.

MelalÈucas, above thirty species, and a beautiful genus of New Holland plants, of easy culture; flowers come out of the wood like fringes. M. elÍptica, M. fÚlgens, scarlet, M. decussÀta, M. hypericifÒlia, M. squarrÒsa, M. linarifÒlia, M. incana, M. tetragÒnia, M. thymifÒlia, are all very fine species, and flower freely if they have been grown from cuttings; the singularity of flower and diversity of foliage make them generally thought of.

MaurÁndias, three species, of very pretty climbing Green-house plants, flowering from March to October. M. BarclÀyana has splendid flowers, large, light blue, campanulate, and very abundant. M. semperflÒrens has rose coloured flowers, of the same character. They will flower best if planted in the ground.

MyrsÍnes, Cape Myrtle, dwarf cape evergreen shrubs covered with small flowers from March to May. M. retÙsa has green and purple flowers; M. rotundifÒlia, flowers white and purple. They will grow in any situation, and are of easy culture.

MÉspilus japÓnica. The plant, known under that name, is now EriabÒtrya japÓnica, Loquat, is a fine plant with large lanceolate, distantly serrated leaves, white underneath; small white flowers on a racemose spike, and produces a fruit about the size of a walnut, of a fine yellow blush colour, and of delicious flavour. If it flowers in the fall, it will require the heat of a Hot-house to ripen the fruit. It is of very easy culture, and its noble aspect is never passed unobserved.

MetrosidÈros, about five species. Many have been added to CallistÈmon. M. flÒrida, M. umbellata, and M. angustifÒlia, are the best species. C. salÍgnum, C. lanceolÀtum, variety semperiflÒrens, C. glaÙcum, once M. speciÒsa, has splendid scarlet flowers and C. formÒsum; these are all beautiful plants, with scarlet flowers. Other two beautiful species with white flowers have been given to AngÓphora. A. cordifÒlia, once M. hÍspida, and A. lanceolÀta, once M. costÀta; these genera are very easily distinguished from any other Australasian shrubs, by the peculiar character of having both sides of the leaves alike. The flowers consist of stamens, stiles, and anthers, coming in hundreds out of the young wood for the length of three or four inches, forming a dense cone crowned with a small twig; leaving capsules in the wood, which will keep their seeds perfect for a great number of years. They grow freely, and the pots should be well drained.

Myrtus, Myrtle, is a well known and popular shrub, especially the common varieties; and was a great favourite, (even to adoration,) among the ancients. It was the mark of authority for Athenian rulers, and is amongst the moderns an emblem of pre-eminence. They are elegant evergreen shrubs, with an agreeable odour. M. commÙnis multiplÉx, double flowering, is a very neat shrub, and flowers abundantly. M. commÙnis leucocÁrpa, White-fruited Myrtle, is quite unique, when the berries are on it. M. itÁlica variagÁta, striped leaved; M. itÁlica maculÀta, blotch leaved, are very fine shrubs; and M. tomentÒsa, Chinese Myrtle, is a magnificent erect growing shrub, with a white down over the foliage; the flowers are the largest of the genus. When they first expand, they are white, and afterwards change to purple, so that there are beautiful flowers of several shades of colour on the plant. We have not the smallest doubt but this species will become in many instances as plentiful as the common myrtle. It is more easily grown, but cannot stand much exposure to the sun in summer. M. tenuifÒlia is a very fine plant, and a native of New South Wales. Myrtles in general should be sprinkled with water in the evenings, to keep off mildew and red spider.

NandÌna domÉstica, the only species, and a popular shrub in the gardens of Japan, where it is called Nandin. It has supra-decompound leaves, with entire lanceolate leaflets, a kind of foliage that is very rare; the flowers are small, whitish green, in panicles, succeeded by berries of the size of a pea; drain the pots well.

NÈrium, (Oleander,) is a genus of beautiful erect growing evergreen shrubs, of the easiest culture, and abundant in flower. N. oleÁnder is the common rose coloured single flowering species, from which six varieties have originated. At present the most popular is N. oleÁnder splÈndens, which has a double rose coloured flower. There is one that has got in our collections as double white which is only semi-double. We have seen a white, variety as double as N. o. splÈndens, and have no doubt but in a few years it will be plentiful. N. oleÁnder elegantÌssimum, a most beautiful plant, with deep silver-edged foliage; and the young wood is striped white and green. We are not positive in respect to the beauty of its flowers, but it has a high character. We have heard of a double-yellow variety, but the reports are not properly authenticated; and we doubt it very much. There are likewise single yellow, single white, and single blotched varieties of N. oleÁnder. They are subject to the small white scaly insect, and should be frequently washed, as has been directed, to keep it off.

Oleas, Olive, about twelve species and varieties. O. EuropÆa longifÒlia, is the species that is cultivated to such an extent in the south of France, and Italy. O. EuropÆa latifÒlia is chiefly cultivated in Spain. The fruit is larger than that of Italy, but the oil is not so pleasant, which is obtained by crushing the fruit to a paste, and pressing it through a woollen bag, adding hot water as long as any oil is yielded. The oil is then skimmed off the water, and put into barrels, bottles, &c. for use. The tree seldom exceeds thirty feet, and is a branchy glaucous evergreen, and said to be of great longevity. Some plantations at Turin in Italy are supposed to have existed from the time of Pliny. It frequently flowers in our collections, but seldom carries fruit; flowers white, in small racemose axillary spikes. O. cupÉnsis has a thick large oblong foliage; flowers white, in large terminale panicles. O. verrucÒsa, foliage flat, lanceolate, and white beneath, branches curiously warted. O. fragrÁns, foliage and blossoms are both highly odoriferous; the plant is much esteemed in China, and is said to be used to adulterate and flavour teas. Leaves are elliptic, lanceolate, and a little serrated; flowers white in lateral bunches. It is subject to the small, white scaly insect, and ought to be carefully kept from them by washing. O. paniculata is a fine species. They are all very easily cultivated.

OxylÒbiums, seven species, plants very similar to Callistachys, with ovate, cordate, light coloured, pubescent foliage, with papilionaceous flowers. O. obtusifÒlium has scarlet flowers; O. retÙsum, orange flowers; and O. ellÍpticum, yellow flowers. They grow freely, and should be well drained; flower from May to August.

PelargÒniums, Stork's Bill. This genus, so universally known amongst us as GerÀnium, from which it was separated many years ago, is a family of great extent and variety, for which we are principally indebted to the Cape of Good Hope. By cultivation from seed many hundred beautiful species and well marked varieties have been obtained. There are about five hundred species, with upwards of two hundred varieties. They are of every character, colour and shade, of the most vivid description. The easy cultivation of the PelargÒnium tribe, or GerÀniums, as they are commonly called, has rendered them very popular; also the agreeableness of scent and fragrance of which many of them are possessed, makes them favourites. If their flowering season was of longer duration, the varieties and species would be quite indispensable in collections; but there is every appearance that in a few years the aspect of them will be changed. The present prevailing colour of the flower, (which has five petals, three hanging and two erect, the erect petals being always of the darkest shade,) is a white or pink ground, with lilac, purple, or pink stripes, flakes, or spots, and blooms from April to June; though they bloom profusely in large bunches, the time is limited. The species and varieties that have a red ground, with black or dark crimson stripes or spots, generally bloom during the whole summer. These, though scarce in the collections of the country, will in a few years root out those whose flowers are of such short duration, and by their blooms charm us half of the year.

The tuberous and fleshy stemmed species are far more interesting to the discriminating inquirer than the common kinds. Their habit and constitution are so peculiar, that we have frequently wondered that they have not been separated into distinct genera. The cultivation of them is more difficult, water being very prejudicial to them when they are inactive. When they are well managed, they flower beautifully, and the colours are very superior and peculiar, having frequently bright green and purple in the same flower. If some of the colours of these could be compounded with the large flowering kinds, those hybridised would be magnificent.

The best method to adopt in impregnating these, is to choose the female, one that has large flowers, of easy cultivation, and as nearly allied in character and other habits as possible. When a flower of the intended female is newly expanded, take a pair of very fine pointed scissors, and cut off the anthers before the pollen expands; then as soon as the summit of the stile divides, apply the pollen taken from the anthers of the intended male plant on a very fine camel hair pencil, or cut out the stigma entirely, and place the anther on the summit of the stile, which, if correctly done, will have the desired effect. As soon as the seed is ripe, sow it in light sandy soil; and when it has come up, take care not to over-water the soil, which would cause them to damp off. When they are about one inch high, put them into small pots, and treat as the other varieties. Have them all distinctly marked until they flower, which will be in the second year from the time of sowing.

PhÓrmium tÈnax, New Zealand flax lily, the only species; foliage resembling an Iris, and very thready. In New Zealand and Norfolk Island, the natives manufacture from this plant a kind of stuff like coarse linen, cordage, &c.; the plant is very hardy, and we would be no way surprised to see it stand the severity of our winters. It bears exposure to the open air in Europe in the 56th degree of north latitude. The flowers are said to be yellow and lily-like; of the easiest culture.

Phylicas, above twenty-five species. Several of them are very pretty growing evergreen shrubs, and of easy culture. P. horizontÀlis, P. squarrÒsa, P. imbricÀta, P. myrtifÒlia, P. callÒsa, P. bÍcolor, and P. ericoÍdes, are all neat growing; flowers small, white, in heads; drain the pots well, and keep them in an airy situation. The foliage of several of the species is downy.

PimÈleas, about fourteen species. Most of them are highly esteemed, and are not often seen in our collections. P. decussÀta is the finest of the genus, both in foliage and flowers, which are red, and in large terminale clusters; P. rÔsea, P. linifÒlia, white, P. spicÀta, and P. drupÀcea, are all fine species. The latter has the largest foliage, which is ovate and accuminate; berry-bearing. They should be well drained. They are very small evergreen shrubs, with white or red flowers.

PittÓsporums, about nine species, with handsome foliage, and small white flowers in clusters, which are fragrant. P. TobÌra is a native of China, and nearly hardy; leaves lucid, obovate, obtuse, and smooth. P. undulÀtum, P. coriÀceum, P. revolÙtum, P. fÚlvum, and P. ferrugÍneum, are very ornamental evergreens, and will grow with the most simple treatment.

PlatylÒbiums, Flat Pea, four species of fine free flowering plants; flowers leguminose; colour yellow. P. formÒsum, P. orÀtum, and P. triangulÀre, are the best; the foliage of the two former is cordate, ovate; the latter hastate, with spiny angles.

PistÀcias, seven species of trees, principally of the south of Europe. There is nothing particular in their appearance, except their productions in their native country. P. terebÍnthus is deciduous, and produces the Cyprus turpentine. P. lentÍscus is the true mastich tree, which is obtained by cutting transverse incisions in the bark. P. vÈra and P. reticulÀta are good species; leaves pinnated; leaflets ovate, lanceolate; easily cultivated.

PlumbÀgos, Lead-wort. There are only two species of any consequence belonging to the Green-house, P. trÍstis and P. capÉnsis. The former is a shy flowerer, but the latter flowers freely; colour beautiful light blue, and flowers in spikes; foliage oblong, entire, and a little glaucous; of very easy culture, and continues in bloom a considerable time.

PsorÀleas, above forty species. A few of them are worthy of cultivation, P. odoratÍssima, P. spicÀta, P. aculeÀta, P. argÉntea, and P. tomentÒsa. They have all blue flowers, and leguminose. They are chiefly low shrubs; and will flower and grow freely; the pots require draining.

Podalyrias, about fourteen species of pretty Cape shrubs; foliage oblong, obovate, and silky-like; the flowers leguminose; colour blue or pink. P. serÍcea, P. styracifÒlia, P. corÚscans, P. argÉntea, P. liparioÍdes, and P. subbiflÒra, are the finest and most distinct species, and flower abundantly.

PetsoÓnias, about sixteen species of dwarf evergreen shrubs; leaves oblong, or lanceolate, hairy, or downy; flowers axillary and solitary; the pots should be well drained, and the plants in summer protected from the sun. P. hirsÙta, P. mÓllis, P. teretifÒlia, and P. lÙcida, are the most distinct, and grow freely.

PrÒteas, about forty-four species. The foliage of this genus is very diversified; flowers very large, terminale; stamens protected by an involucrum; many-leaved and imbricated; which is very persistent. P. cynaroÍdes has the largest flower, which is purple, green, and red. P. speciÒsa, P. umbonÀlis, once P. longifÒlia, P. melaleÙca, P. grandiflÒra, P. coccÍnea, P. cenocÁrpa, P. pÁllens, P. formÒsa, P. magnÍfica, P. speciÒsa rÚbra, and P. mellÍfera, will afford a very good variety. It is almost impossible to describe their true colour, it being so various; red, white, straw, brown, green, and purple, are most predominant, and frequently to be seen in the same flower; the plants must be well drained; and during warm weather be careful that they are not neglected in water, for if they are suffered to droop, they seldom recover. For this reason the pots ought not to stand in the strong sun; the plants can bear it, but to the roots it is injurious.

PultenÆas, about forty species, pretty little dwarf growing shrubs of New South Wales; flowers small, leguminose, all yellow, with a little red outside of the petals. P. villÒsa, P. obcordÀta, P. argÉntea, P. plumÒsa, P. flÉxilis, shining leaved, fragrant; P. cÁndida, and P. strÌcta, are all fine species, and esteemed in collections. The leaves are all small; they require an airy exposure, and the pots drained.

RhododÉndrons (Rose tree), a magnificent genus, and contains some of the most superb and gigantic plants that adorn the Green-house. All the AzÀleas (except A. procÚmbens) both Chinese and American, have been arranged under this genus. At present the most admired is R. arbÒreum, with varieties. R. arbÒreum has deep scarlet flowers, with dark spots and flakes campanulated, and in large clusters; leaves lanceolate, acute, rough, and silvery beneath. R. arbÒreum albÚm is very rare. R. arbÒreum supÉrbum, flowers same shape as arbÒreum, colour bright scarlet; foliage one third larger, but not silvery beneath; grows freely, and generally thought the finest variety. R. arbÒrea Álte-ClÀrance is also very superb. There are several other varieties of minor note. A Green-house without some of the scarlet varieties of that plant, is deficient of a flower whose beauty and grandeur are beyond the highest imagination. It is a native of Nepaul in India, and when found by Dr. Wallach awakened the ambition of every cultivator and connoisseur in Europe. There are several other species brought from that country lately, but none of them has yet flowered. They are highly valued from the productions of the above; the species are R. campanulÀtum, R. anthopÒgon, and R. cinnamÒmeum. This is named from the colour of the leaves, which are very peculiar and very handsome; the flowers are said to be rose-coloured. These three last cannot be purchased under an immense price; the others have been rarely seen in our collections, but another year or two will make them more plentiful. Their beauty of flower is beyond description. The pots should be well drained, and if they are large, put several pieces of sandy stones or potshreds around the side, for the fine fibres delight to twine about such, being mountainous plants.

RoÉllas, pretty leafy shrubs, with blue terminale funnel-shaped flowers, lip-spreading; R. cilliÀta, R. spicÀta, and R. pedunculÀta, are the finest of the genus. The pots must be well drained, and care taken that they are not over-watered.

SÁlvia (Sage), is an extensive genus of soft-wooded, shrubby, or herbaceous plants; very few of them do well in the Green-house, and many of them are very trifling, having no other attraction than the flower, and those of the tender species, when compared with S. Élegans, S. splÉndens, S. cÆrÚlea, and S. coccÌnea, (which in artificial climates constitute the standard of the genus,) are not worth cultivation. These last mentioned, if kept in the Green-house, will merely keep in life, but a situation in the Hot-house would cause them to flower frequently. The best method to adopt with the summer flowering kinds, is to plant them in the garden in May; they will grow strong and flower abundantly, and in the fall they can be lifted, and preserved during winter in pots. They neither grow nor flower so well as when planted out, and even a slip planted in the ground in moist weather will root in a few days, grow, and flower in a few weeks. S. splÉndens is the best to select for the purpose. S. aÙrea, S. paniculÀta, and S. Índica, are fine species. The latter is white and blue, with large leaves; flowers monopetalous, and irregular; colour generally red or blue in spiked whorls. All will grow easily with encouragement.

SenÈcios. Some species of this genus are pestiferous weeds all over the world. They are found near the limits of perpetual snow, where neither tree nor shrub is able to rear its head. Yet there are three species that are neat little plants, and are worthy of a situation, viz. S. grandiflÒrus, S. venÚstus, and S. cinerÁscens, with the double white and red variety of S. Élegans. The two last varieties are free flowering, but if allowed to grow several years, they become unsightly. Being very easily propagated, a few cuttings of them should be put in, in September, and in two weeks they will strike root, when they may be put in pots to keep through the winter, and then planted in the garden, continuing to renew them. The other mentioned species should be frequently done the same way. Do not keep them damp during winter, or they will rot off. Keep them in an airy exposure.

SchÓtias, a beautiful genus of six species, which will require the warmest part of the Green-house to keep them. The foliage is handsome; leaves compound: leaflets oval-lanceolate, and in pairs from six to ten; S. speciÒsa, crimson, flowers nearly papilionaceous, and in bunches, the most superb of the genus. S. alÀta, S. latifÒlia, once OmphalÒbium SchÓtia, and S. tamarindifÓlia, are the finest; the flowers of the others are red. The pots require to be drained, and the plants protected from the hot sun.

SwainsÒnas, four species of free flowering, soft wooded shrubs, natives of New South Wales. S. galigifÒlia, S. coronillÆfÒlia, and S. astragalifÒlia, are red, purple, and white; leguminose flowers in spikes from the axils, are of easy culture, and deserving of a situation; the foliage is pinnate; leaflets ovate, acute.

ScÒttias, three species of valuable plants; S. dentÀta, with scarlet leguminose blossoms; leaves opposite, ovate, accuminate, serrate; S. angustifÒlia has brown flowers; S. trapezifÒrmus, leaves ovate, acute, serrulate. We do not know the colour of its flowers; the pots must be well drained, and the plants kept in the warmest part of the Green-house, and near the light.

SparrmÁnnias, are strong growing Green-house shrubs. S. africÀna, is a plant very common in our collections, with large three lobed cordate leaves, hairs on both sides; flowers from March to July. S. rugÓsa. The leaves are rugged; flowers of both are white, in a kind of corymb, supported by a long footstalk; buds drooping, flowers erect. There is a plant known in our collections, as the free-flowering SparrmÁnnia, (which is EntÈlia arborÉscens,) and is easily distinguished from SparrmÁnnia by the leaves being cordate, accuminate, and otherwise, by all its filaments being fertile, and the flowers more branching, and blooming from November to June, profusely; very easily cultivated, and desirable.

SphÆrolÒbiums, only two species of leafless plants, with yellow and red leguminose flowers, which proceed from the young shoots. S. vimÍneum and S. mÉdium. They flower freely, and are easily cultivated. The old wood should be frequently cut out where it is practicable. Drain the pots.

SprengÉlia incarnÀta,, the only species, a very pretty plant, allied to EpÀcris; small foliage, long, accuminate; flowers small, pink, bearded, and in close spikes; grows freely, delighting in shade. The pots must be well drained, and the plants, when dormant, watered sparingly, for if they get sodden about the roots, they very seldom recover.

StylidÍums, six species of pretty litte plants, with small linear leaves, and remarkable for the singular elasticity of the style or column, which, when the flower is newly expanded, lays to one side, and on being touched with a pin starts with violence to the opposite side. S. graminifÒlium, S. fruticÒsum, S. laricifÒlium, and S. adnÀtum, are all free flowering; flowers in spikes, very small; colour light and dark pink; blooms from April to July. S. adnÀtum is half herbaceous, and should, when growing, be kept nigh the glass, or it will be drawn, and the flowers become of a pale colour. They are all of easy cultivation.

StyphÈlias, seven species of very showy flowers, with mucronate leaves; corolla in a long tubular form, having several bundles of hairs in it; segments reflex and bearded. S. tubiflÒra, crimson, S. triflÒra, crimson and green; S. adscÉndens, and S. longifÒlia, are beautiful species. They grow freely, and should be well drained, as too much water is very hurtful to them. In summer they ought not to be much exposed to the hot sun, or the foliage will become brown.

SalpiglÓssis, four species of fine herbaceous Green-house plants, natives of Chili. The flowers are tubular and campanulate. S. pÍcta, flowers white and blue painted; S. atropurpÙrea, flowers dark purple, and S. isnuÀta, flowers crimson, are superb, and if planted in the garden during summer will flower profusely. They must be lifted in October, and taken under protection.

TagÈtes lÙcida is found in many of our collections. The leaves are simple, oblong, and finely serrated. When rubbed by the hand, they have an agreeable fragrance; the flowers are syngenesious, small, and in terminale bunches. It is herbaceous; and when about an inch grown should be divided and potted into five inch pots. Repot it again about the first of June. It keeps in flower from July to November.

TestudinÀria, Elephant's foot, or Hottentot's bread, two species remarkable for their appearance. The root or bulb, if it may be so called, is of a conical shape, and divided into transverse sections. Those of one foot diameter are computed to be 150 years of age. It is a climbing herbaceous plant, with entire reniforme leaves of no beauty; flowers small; colour green. The pots must be well drained, for when the plant is inactive it is in danger of suffering from moisture, and ought not to get any water. T. ElephÁntiphes and T. montÀna are the species, natives of the Cape of Good Hope, and require the warmest part of the house.

TÁxus nucÍfera, is the only species that requires protection, and bears a small acorn; flowers are trifling; an evergreen, with ovate, lanceolate foliage, thickly set on the wood; will grow in any situation. There is a plant in our collections known as T. chinÉnsis or T. elongÁta, which is PodocÁrpus elongÀtus. It has lanceolate leaves, erect growing, and very hardy; flowers moeonacious, and of no estimation except to the curious.

TelopÈa speciosÍssimus, is the only species, and was once called EmbÓthrium speciosÍssimus. It is now called TelopÈa in allusion to the brilliant crimson flowers, which from their great size are seen at a large distance, and which render it one of the most conspicuous productions of New South Wales. The leaves are oblong, deeply toothed, veiny, and smooth; wood strong; flower ovate, connate, and terminale, and of considerable duration. There ought to be a specimen of it in every collection. The pots must be well drained, and the plant in the extreme heat of summer not too much exposed to the sun.

TempletÒnia, a very pretty genus, containing only two species. T. retÙsa is an erect growing shrub, with wedge-shaped green leaves. T. glÁuca, leaves glacuous, blunt, and a little apiculate; flowers of both scarlet. They are leguminose plants of free growth, and should be well drained; blooming from April to June.

TristÀnias, seven species of evergreen shrubs. Several of them require to be very large before they flower. T. neriifÒlia is a very neat little plant, and flowers abundantly; colour yellow; shape star-like, and in clusters; leaves lanceolate and opposite. T. confÉrta, white flowers in spikes, leaves alternate. T. suavÈolens, sweet-scented; flowers yellow. They are all of very easy culture.

VerbÉnas. A few of these are showy, herbaceous, Green-house plants. V. chamÆdryfÒlia, lately known as V. MelÍndres, is a beautiful plant of a procumbent habit; flowers brilliant scarlet, in glomerated heads from the axils of the young shoots; blooming from April to October. A large plant will appear as a solid mass of scarlet. V. lambÉrtii and V. pulchÉlla are also very pretty; colour, rose and lilac. A very good method of treating these plants, is, to plant them in the garden in April; and give them copious waterings in dry weather, and they will flower profusely, lifting some of the plants before frost, to preserve them during winter. They ought to be allowed to run according to their nature; for if tied up, they will not do so well, being in that way too much exposed. There is a plant known in our collections as VerbÉna triphylla, which is Aloysia citriodÒra. The flowers are in long spikes, very small, and pale purple. The celebrity of the plant is in the foliage, which is linear, lanceolate, ternate, and it has the most agreeable fragrance in the vegetable world. It is of very easy culture, and has been known to survive the winter, in open air, in Philadelphia. It is deciduous, and would do to plant in the garden during summer, lifting it again before frost, and putting it under protection through winter. When large before it begins to grow, in spring cut it into a neat shape or form.

VibÚrnums. A few of these are very ornamental evergreen shrubs, and almost hardy. V. tÌnus is the well known Laurestine, (or what is commonly called Laurestinus,) is of the easiest culture; flowers small white, and in large flattened panicles; blooming from February to May, and universally esteemed. It will stand the winter by a little protection, but the flower buds being formed in the fall, the intense frost destroys them; consequently, it will not flower except by the buds, which sometimes form early in summer. V. lÙcidum is a good species, and superior in flower and foliage to the former, but does not flower so freely, when the plants are small. When they grow large, they flower profusely. There is a desirable variegated variety. V. odoratÍssimum has smooth evergreen, oblong, elliptic, distantly toothed, leaves, and frequently a stripe in them, is sweet-scented, and a free flowerer. V. hirsÚtum has flowers similar to the above; foliage ovate, with rough brown hairs on both sides, and very characteristic. V. strÍctum variagÀtum is a very fine variety, and upright growing. These plants are all very desirable, blooming early in spring, and continuing for several months; all easily cultivated.

ViminÀria denudÀta, the only species. This plant is remarkable for its twiggy appearance, but it has no foliage, except when growing from seed. It has at the extremity of the twigs or shoots, an ovate, lanceolate, leaf, disappearing when the plant grows old; the flowers are small, yellow, coming out of the young shoots, to the astonishment of the beholder. It grows freely.

VirgÍlia capÈnsis is a beautiful cape shrub, with a compound leaf of twenty-five leaflets, ovate, lanceolate, edges hairy; flowers in spikes at the axils; colour blue and leguminose. The pots require to be well drained, and the plants protected from the sun.

VolkamÈria japÓnica. There is a plant known in our collections under that name, which is ClerodÉndron frÀgrans mÚltiplex. It keeps in a good Green-house, and flowers well, frequently blooming during winter, and if planted in the garden during summer, will flower superbly. The flowers have a delicious fragrance; but if the foliage is rubbed with the hand, the smell is not so pleasant. The leaves are large, round, ovate, and tomentose; flowers corymbose, compact, and terminale. There are several fine plants in ClerodÉndron belonging to the Hot-house. This plant will not bear much fumigation.

WitsÈnias, four species. W. corymbÒsa is a plant that has stood in high estimation ever since it was known, but unfortunately there is a very inferior plant, AristÈa cyÀnea, got into our collections under that name. The panicles of W. corymbÒsa is quite smooth; those of AristÈa are hairy, which is itself sufficient to detect them; but otherwise the appearance of W. corymbÒsa is much stronger, and more erect growing, not inclining to push at the roots so much as AristÈa. The foliage is lanceolate and amplexicaule, the leaves having much the nature and appearance of Iris. The plant is of easy culture, and blooms from November to April; colour fine blue. The true one has come into the country lately. W. ramÒsa is a very fine species, similar to the above; flowers yellow and blue; plant branching.

WestrÍngias, a genus of four species, very like the common Rosemary. W. rosmarinifÓrmis, leaves lanceolate, and silvery beneath; W. longifÒlia is similar; both have small white silvery flowers, and are easily cultivated.

ZÀmias, about twenty species, eight of which belong to this compartment. The foliage is greatly admired, and is in large fronds, with oblique, lanceolate leaflets. Several of them glaucous. It bears heads of flowers of a brown colour in the centre of the plant, very like large pine cones. Z. hÓrrida, the finest, Z. pÚngens, Z. spÍralis, and Z. latifÒlia, are the most conspicuous. They must be kept in the warmest part of the Green-house; and give them large well drained pots. They are imported from the Cape of Good Hope. All the plants herein named requiring to be drained. In preparing the pots, place first a piece of broken pot, or any similar substitute, with the convex side on the hole of the pot, and then put in a few, or a handful, (according to the size of the pot,) of shivers of broken pots, or round gravel, about the size of garden pease. Those that we have mentioned in this Repotting, as to be done in this, or beginning of next month, is not intended to apply to plants in general, large and small, but to those that are young, and require encouragement, or to those that were not shifted last autumn. The roots must not be disturbed, but the ball turned out entire; and put as much earth as will raise the ball within about an inch of the rim of the pot. Press the earth down around it with a thin-narrow piece of wood, frequently shaking it that no vacancy may be left. If the roots are rotten, or otherwise injured, take all such off. If this be the case, the plant will be sickly. Give it a new pot of a smaller size, administering water moderately until there are visible signs of fresh growth. The plants must not be disturbed while flowering; let the repotting be done afterwards. Plants are, at certain stages of growth, if in good health, in such a state that no one can err in shifting them when desirous to hasten their growth. Those plants that make two or more growths during the summer may be repotted in the interim of any of these growths, and all others just before they begin to push in the spring; that is, when the wood buds are perceptibly swelled. Never saturate with water fresh potted plants. There are many kinds that, without injury, could be repotted when growing; but it requires an experienced operator to decide. It would be of no material service to enumerate them here. When done potting, tie all up neatly with stakes rather higher than the plant, that the new shoots may be tied thereto during their stage of growth, to prevent them from being destroyed by the wind. There may be many that do not require repotting, but would be benefited by a top-dressing. This should be done by probing off all the surface earth down to the roots, replacing it with fresh compost, suitable to the nature of the plant.

When the above is done, arrange all the plants in proper order, and syringe them clean; but if there are any of the Green-fly, they must be fumigated previous to syringing. Take an opportunity, on the first fine day, to wash out all the pavement of the house, which should be made dry before the evening if the nights are cold. Thus every part of the house will be in order before the hurry of the garden commences.

OF ENARCHING OR GRAFTING BY APPROACH, also termed ABLACTATION.

In this method of grafting, the scion is not separated from the parent plant until it is firmly united with the stock; consequently, they must stand contiguously. We intend the following method to apply directly to CamÉllias, as they are the principal plants in the Green-house that are thus worked. The criterion for the operation is, just as the plants begin to grow, either in spring or mid-summer. Place the stock contiguous to the plant where the graft or enarch is to be taken from. If the branches, where the intended union is to take place, do not grow at equal heights, a slight stage may be erected to elevate the pot that holds the lower. Take the branch that is to be enarched, (the wood of last or previous year is the most proper,) and bring it in contact with the stock; mark the parts where they are to unite, so as to form a pointed arch. In that part of the branch which is to rest against the stock, pare off the bark and part of the wood to about two or three inches in length, and in the side of the stock which is to receive the graft, do the same, that the inside rind of each may be exactly opposite, which is the first part where a union will take place. Bind them firmly and neatly together with strands of Russia matting, and protect the joint from the air by a coat of close composition; clay of the consistency of thick paint, turpentine, or wax, will equally answer. Finish by fastening the grafted branch to the head of the stock or a rod. Many practitioners make a slit or tongue into the enarch and stock, but we find it unnecessary, more tedious, and likewise more danger in breaking. CamÉllias are also grafted, and budded, but these two operations require great experience and continued attention, and seldom prove so successful as enarching. When they have perfectly taken, which will be after the first growth is over, begin to separate them by cutting the scion a little at three different periods, about a week apart, separating it at the third time. If the head is intended to be taken off the stock, do it in like manner after the second growth is over. By the above method, many kinds can be grown on the same stock. The same plan applies to all evergreens.
