Pseudobulbs clustered together, 2 to 4 inches long, compressed, ovate or almost round, smooth and glossy, 2-leaved. Leaves 6 inches to a foot long, leathery, oblong-ligulate, obtuse, rather shorter than the raceme. Raceme issuing at an early stage from the young growth, pendulous, many-flowered, rarely branched, longer than the leaves. Sepals and Petals similar in form, pure white, or in some varieties of a faint blush or rose-colour, frequently sprinkled with minute red dots, oblong, obtuse, about an inch long. Lip unguiculate, kidney-shaped, channelled (with the solid edges turned up) along its base, on which there is a patch of yellow, with a few bright dots in the position where a crest (here entirely wanting) is usually placed; the colour of the disk of the lip varies in different specimens, being sometimes entirely white and sometimes tipped with faint rose-colour or deep-crimson. Column with upper and lower wings (all of which are toothed), that on the back being rounded and the others truncated. Early in the present century, two Spaniards—La Llave and Lexarza by name—settled at the Mexican town of Valladolid, in the fertile province of Mechoacan. They were both attached to botany, but the younger of the two, Lexarza, was so attracted by the beauty of the numerous Orchids of the district that to these he devoted himself with an ardour that would have done honour even to the Lindleys and Reichenbachs of our own day. As the result of his labours a little work—'Orchidianum Opusculum' he modestly styled it—presently made its appearance, wherein about fifty species, all at that time new to science, were described with remarkable accuracy and skill. Among the number there was a plant,—Cuitlauzina pendula he called it,—said to be of surpassing loveliness and to form an undoubtedly new genus the distinctive characters of which were minutely given. As time went on and the rage for Orchids developed itself in Europe, a keen desire was naturally felt by cultivators to add so fine a plant to their lists; but although many collectors visited Valladolid and laid hands upon nearly all the other desirable Orchids described by Lexarza, still nothing was heard of the Cuitlauzina, and on the cover of the latest number of Dr. Lindley's 'Folia Orchidacea' its name may be found in the list of genera "unknown to the author." About the same time I myself addressed a letter to the 'Gardeners' Chronicle' urging some adventurous traveller to take ship for New Spain, mainly with the object of instituting another search for the tantalizing plant that had hitherto eluded our grasp. Yet all this while Cuitlauzina pendula was amongst us, and indeed had been an established favourite for upwards of twenty years! But if so, it may well be asked, how came it to pass that it was never recognized? For a full reply to this very natural inquiry I must refer the reader to a most ingenious article in 'Bonplandia' (Jahrg. iii. No. 15, 16), by the younger Reichenbach, to whom all the credit is due of having solved a great botanical puzzle, and proved to demonstration that the Cuitlauzina pendula of Lexarza is none other than the Odontoglossum citrosmum of Lindley.[4] Under these circumstances, however undesirable the meddling with established names, I scarcely see how, in common justice to Lexarza, we can do otherwise than adopt his specific name of pendula, more especially as it happens that the plant to which he originally gave it remains to this day the only one out of nearly a hundred Odontoglossa that has flower-stems which are strictly pendulous. Our gardens contain many varieties of O. pendulum, of which, though all are beautiful, some are far superior to others. That represented in the Plate, and which forms a part of Mr. Rucker's collection, is among the best. Mr. Rucker keeps it in his coolest house, where it is perfectly at home, and produces a profusion of its lovely drooping racemes in May and June. It should always be grown in a pot. Dissections.—1.
