which the small oblong-ligulate sepals and petals are pale 

 green, with a few bars of purplish red, and the lip is large 

 reniform bilobed and bright yellow, with a few crimson lines 

 on the claw, above which is a crest, consisting of a depressed 

 callus, three-lobed at the apex, and having compressed lamellae 

 in front. It succeeds well upon a block. The plant flowers 

 during the autumn months, and remains for a long time in 

 bloom. — Brazil.

0. COncolor, Hooker. — A very distinct and beautiful species, 

 with small tufted ovate or ovate-oblong compressed ribbed 

 pseudobulbs, and a pair of subcoriaceous oblong-linear or 

 ligulate bright green leaves. The flowers are large and of a 

 pure yellow, one and a half to two inches in diameter, pro- 

 duced upon radical scapes in long pendulous racemes, the 

 sepals being lanceolate, and the lip large flat cuneate sub- 

 panduriform emarginate, and marked at the base with a pair 

 of orange-coloured lamellae. It blooms in March and April, 

 running on into May or sometimes into June, the two latter 

 being the principal exhibition months. This is a fine subject 

 for growing in baskets in the cool house, where it succeeds 

 best. — Brazil : Organ Mountains.

0. COrnigeriim, Lindley. — A highly ornamental species, and 

 one that is very distinct both in habit and appearance. The 

 pseudobulbs are oblong suleate, about three inches long, bear- 

 ing a solitary leaf which is oval and striate, deep green, and 

 of a peculiarly thick and fleshy texture. The flowers are 

 small but numerous, and are produced in a very elegant 

 drooping close panicle on a slender scape upwards of a foot in 

 length ; this panicle is developed after the gi'owth is mature, 

 and on it are borne the beautifully gay flowers, which are 

 yellow spotted with deep red ; its season of flowering is April 

 and May. The lip is panduriform (or obovate subrepand) 

 wavy, with a horn-shaped lobe on each side at the base. —

0. Crispuni, Loddiges. — A remarkably handsome large-
