O. CHRYSOPS, Rohb. f. — This is allied to O. bicallosum. The leaves are 

 said to be short, reddish; flowers racemose; sepals cuneate oblong, light brown; 

 petals broader, undulate, blunt, of the same colour as the sepals ; lip bright 

 yellow, middle lobe large, reniform. — Native country not stated. 



O. CHRYSORH APIS, Bclib. f. — A species allied to 0. comigerum, and imported 

 by Messrs. F. Sander & Co. Pseudobulbs fusiform, terete, dark green, 3 to 

 4 inches long ; the leaves are from 6 to 7 inches long, cuneate oblong-lanceolate ; 

 sepals and petals light sulphur-yellow spotted with dark brown ; lip yellow, the 

 front lobe very large reniform. — Brazil. 



O. CHRYSOTHYRSUS, Rchb. f. — A very showy and abundant-flowered 

 Oncid, of free and compact growth, seldom attaining more than a foot in 

 height, the pseudobulbs being 2 to 3 inches high, oblong compressed, and at 

 length ribbed, and supporting a pair of oblong-acute light green leaves ; the 

 scape is some 2 to 3 feet in length, terminated by a thyrsoid panicle of numerous 

 showy and lovely flowers, of 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.

O. CILIATUM — See 0. babbatum. 



O. CONCOLOR, Hooker. — A very distinct and beautiful species, with small 

 tufted ovate or ovate-oblong compressed ribbed pseudobulbs, and a pair of sub- 

 coriaceous oblong linear or ligulate bright green leaves. The flowers are large 

 and of a pure yellow, I5 to 2 inches in diameter, produced 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.
