ONCIDIUM. 603 



O. CAVENDISHIANUM, Bateman.—A very showy and noble species of bold 

 and striking habit, remarkable for the absence of pseudobulbs, the large broad 

 fleshy rich green leaves, together with the stout flower scape, growing out from 

 between a few stout imbricated seal}- bracts. The bright yellow flowers are 

 produced in great abundance on the stout, tall branching scapes, and appear in the 

 dull months of winter, a fact which greatly increases its value, for even at that 

 season they retain all their brilliancy for several weeks. The flowers are about 

 an inch in diameter, the sepals obovate-obtuse with the upper one arched, 

 greenish-yellow spotted with bright chestnut, the petals oblong-obtuse wavy and 

 of the same colours, and the lip three-lobed, the lateral lobes roundish un- 

 guiculate, the middle one larger reniform deeply emarginate and of a, pure 

 bright yellow colour ; it has a crest of four prominent tubercles. In 0. pachy- 

 phyllum,yfkich. Lindley considers a form of the same plant, the sepals and petals 

 are spotted with crimson. Eeichenbach keeps them distinct, and figures in 

 Xenia a golden-lipped variety of pachypliyllum. It may be grown on a block or 

 in a pot, in the Catthya house, but on account of its size seems to do best in the 

 latter. — Guatemala.

O. CEBOLLETA, Sivartz. — This it appears is one of the oldest known Oncids, 

 having been described as far back as 1800 ; it is also very widely distributed in 

 its native country, but not being an attractive plant it has never found much 

 favour with orchid growers, and as a consequence it is not frequently seen in 

 collections. The leaves are terete, exceeding 1 foot in length; flower scapes 

 longer than the leaves, erect, many-flowered ; flowers about 1 inch or more in 

 diameter; sepals and petals yellow spotted with reddish-brown, wavy; lip 

 bright yellow, three-lobed. It appears to be a very variable species, and several 

 forms described as specifically distinct have been referred to this species by 

 Lindley. — Mexico ; West Indies ; Brazil ; Paraguay.

O. CEPULA.— See O. Cebolleta. 



O. CHEIROPHORUM, Jlclib. f. — A very pretty dwarf-growing species, pro- 

 ducing dense slender panicles of small golden yellow sweet-scented flowers. It 

 has small ovate ancipitous pseudobulbs, linear-lanceolate acute leaves, and dense 

 short-branched panicles of flowers, which, though not of large size, should secure 

 the admission of the species to any choice collection on account of its fr'ee- 

 blooming properties and its delightful fragrance ; the lip is comparatively large, 

 and three-lobed ; it flowers from October to December, and should be grown 

 in the Odontoglossum house. — Yeragua; Volcano of Chiriqui.
