jjseudobulbs. The showy flowers are produced on elongated panicles which 

 in'oceed 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 flve-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.

O. DASYTYLE, Bchb. f. — A beautiful dwarf-growing species with ovoid 

 ancipitous rugose pseudobulbs. from which proceed a pair of linear-lanceolate 



leaves 4 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 reni- 

 form 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. Introduced by us 

 in 1872. — Brazil : Organ Moimiains.
