ONCIDIUM. < 481 



0. CUrtum, Lindley. — A very handsome and distinct species, 

 of compact growth, somewhat resembHng 0. crisjyum in 

 foliage and in the shape of the pseudobulbs. The showy- 

 flowers are produced on elongated panicles which proceed 

 from the base of the bulb, the sepals and petals obovate 

 obtuse yellow barred and blotched with cinnamon brown, 

 the latter undulated, the roundish bilobed undulated lip 

 golden yellow having a broad margin of cinnamon brown, with 

 golden auricles at the base on each side the five-lobed crest, 

 around which many warts are scattered. It blooms during 

 the spring months, and lasts several weeks in perfection. 

 The plant will succeed best either in a basket or on a block 

 with plenty of drainage. — Brazil.

0. dasystyle, Bchh. f. — A beautiful dwarf-growing species 

 with ovoid ancipitous rugose pseudobulbs, from which pro- 

 ceed a pair of linear-lanceolate leaves four inches long, and 

 a short slender peduncle terminated by a few gay blossoms, 

 of which the incurved sepals and lanceolate petals are whitish 

 yellow with handsome maroon-brown spots, and the dilatately 

 reniform anterior blade of the lip is sulphur, the small side 

 lobes marked with oblique chestnut brown bars, while at the 

 base is a beautiful elongated obcordiform callus of a distinct 

 blackish purple, from which dark purple veins radiate over the 

 disk. It produces its flowers during the months of January 

 and February, and is to be regarded as rather a gay little 

 plant of the smaller-growing section. This species should 

 be grown in the cool house suspended from the roof. — Brazil :

0. divaricatum, Lindley. — A small but abundant-flowered 

 species, with roundish compressed monophyllous pseudo- 

 bulbs, oblong obtuse concave coriaceous leaves, and scapes 

 three to four feet long, bearing a divaricate panicle of small 

 flowers produced during the summer months, and continuing 

 in perfection a long time. The sepals and petals are obovate 

 obtuse yellow with the basal half red, and the lip has 

 roundish lateral lobes and an intermediate roundish subcordate 

 emarginate lobe of a pale yellow spotted with red. The 

 crest forms a pubescent four-lobed cushion. This, when well
