 Acoidium fuscum. Mihi in horiis. 



Imported from Mexico by Mr. Kniglit, of the King's 

 Road, from whom I received it in flower in July of last year. 

 Shortly after it was sent me by Mr. Bateman. It is a stove 

 epiphyte, and apparently by no means of difficult cultivation. 



When I first received it the genus had not been distin- 

 guished, and I called it Acoidium fuscum, from aKO-q, an ear, 

 in allusion to the two ears of the column ; but Mr. Poppig 

 having subsequently figured and described a second species 

 under the name of Trichocentrum pulcJirum, the former must 

 give way. 



* From Qpil rpixoc a hair, and Kevrpov either a spur or a centre ; but the 

 applicability of the word is not apparent, nor is it explained by its author, Mr. 

 Poppig.
