Bulbophyllum is a large and remarkably polymorphic 
genus, extending throughout the tropics of both hemispheres. 
Upwards of five hundred species have already been described, 
and although the great majority are not sufficiently attractive | 
for general cultivation, there are numerous striking excep- 
tions. Already more than twenty species have been 
figured in the Botanical Magazine, several of them being 
very remarkable in character. B. Beccarii, Reichb. f. 
(t. 6567), a Bornean species, is the giant of the genus; 
it has an odour that is extremely disagreeable. B. grandi- 
florum, Blume (t. 7787), a native of New Guinea, is 
equally remarkable for the size of its individual flowers. 
B. barbigerum, Lindl. (t. 5288), a native of West Tropical 
Africa, is remarkable for its large hairy lip, so delicately 
balanced as to oscillate in the slightest breeze. B. lemnis- 
catum, Lindl. (t. 5961), a native of Burma, has a long 
club-shaped appendage suspended from the back of each
