ODONTOGLOSSUM CARINIFERUM, Lindl. Fol. Orch. 
Habitat in America CENTRALI, Reichenbach. 
DESCRIPTION. 
PSEUDOBULBS 3 or 4 inches long, oblong, smooth, bearing 2 broadish, leathery, sharp-pointed Leaves. Soare longer than 
the leaf, panicled with zigzag branches. Bracts triangular, short. Srrars and Purans 1 inch long, greenish 
outside, but of a purplish-brown inside, distinctly keeled at the back. Ture yellowish-white, sessile, ligulate at its 
base, but suddenly changing into a broad reniform plate, which is apiculate in front, and at its base adjoins the crest, 
which consists of 2 nearly prostrate, irregularly toothed, rhomboid lobes on either side, with 3 finger-like pro- 
cesses in front. COLUMN elongated, with transparent crenulate wings, its anther-bed scarcely margined. 
For the opportunity of figuring this pretty Odontoglossum Y am indebted to the kindness of the Bishop of Win- 
chester, in whose collection at Farnham Castle it flowered profusely in November last. A fortnight afterwards I also 
received specimens from Mr. Rucker, but the flowers of his variety were scarcely so bright in their colouring as those of 
the Bishop’s plant. 
O. cariniferum, although now figured for the first time, appears to have been introduced several years ago to German 
collections, and from some of these it has, no doubt, found its way to England. It is a native of Central America, where 
it probably affects a high elevation, as it succeeds perfectly under cool treatment, both at Farnham Castle and at West 
Hill. Its flowers continue in perfection for many weeks.
