  ODONTOGLOSSUM PHALÆNOPSIS, Rchb. fil. MOTH-LIKE ODONTOGLOSSUM. O. (Leucoglossum, Lindl.) pseudobulbis ovatis obtuse ancipitibus 1-2-phyllis, foliis linearibus acutissimis racemis bi- vel trifloris spithamÆis longioribus, sepalis oblongo-ligulatis acutis, petalis latioribus obovatis obtusis; labelli ampli pandurati emarginati bilamelligeri disco velutino, columnÆ alis abbreviatis membranaceis. Odontoglossum phalÆnopsis, Rchb. fil. in Seemann Bonplandia, ii. 278; Pescatorea, Linden et Rchb. fil. ii. 44. Miltonia Pulchella, Hort. Habitat in N. Granada, prope Aspasica, alt. 5-6000 ft., Schlim. DESCRIPTION. Terrestrial. Pseudobulbs nearly two inches long, ovate, bearing one, or more frequently two, narrow linear, very acute Leaves, less than a foot long, and usually withered at the extremities. Raceme nodding, shorter than the leaves, furnished with a few small acute Bracts, and bearing two, or occasionally three, very large and handsome flowers, which, the markings of the lip excepted, are of a uniform white. Sepals oblong, sharp-pointed, about an inch long. Petals broader than the sepals, obtuse. Lip fiddle-shaped, its front portion deeply emarginate, spread out nearly flat, very broad, its side portions much smaller, rounded, and with two continuous upright lamellÆ on its velvety disk; the lip has two large irregular pale-crimson blotches on its anterior portion, with concentric lines of the same colour on its lower portion, with a small patch of yellow on either side the isthmus (i.e. point of junction between the upper and lower divisions of the lip). Column short, with membranous wings much abbreviated. This most charming Odontoglossum was discovered in the year 1850 by M. Schlim at that time engaged in exploring the higher regions of New Granada in the service of M. Linden to whose well-known horticultural establishment at Brussels he had the honour of introducing it. The species was seen in flower for the first time in the year 1856 when it appeared at some Horticultural Exhibitions both on the Continent and in London and, as may readily be conceived, attracted universal admiration. Since that time its lovely blossoms have been rarely produced, owing no doubt to its cultivation having been imperfectly understood. It has however, I believe, bloomed occasionally in the collection of the Lord Chancellor of Ireland, and more recently in that of E. M‘Morland, Esq., of Haverstock Hill, with whom it thrives amazingly, and to whose kindness I am indebted for the opportunity of figuring it. In its native country it is found in a mild climate growing on the ground, or upon rocks in moist and shady situations, and by simply imitating these conditions Mr. M‘Morland cultivates it with the most perfect success. His plants are kept in pots, with living moss on the surface, and their base resting in pans of water the evaporation from which cannot fail to be highly beneficial. The temperature of the house in which they are grown is that of an ordinary greenhouse, but the air is always humid, and water is freely given because, in consequence of the open potting, it can pass as freely away. The plants seem to grow and flower almost all the year round, though their proper and principal flowering-season is in May and June. O. phalÆnopsis is entirely distinct from any species of the genus yet in cultivation, but it is allied to a still finer plant detected by Warszewicz in Costa Rica, and called in honour of its discoverer O. Warszewiczii by Professor Reichenbach. Dissections.—1. Lip. seen sideways; and 2. Front view of lip: both magnified. Plate IV Odontoglossum Insleayii.
