ORCHIDACEiE 



which the accpmpanying plate was prepared, bears about three 

 distichous leaves. In the illustration the vegetative parts were 

 prepared from a co-tj^e in my herbarium and the flower from 

 the type specimen deposited in the herbarium of the Bureau of 

 Science at Manila. 



The genus Angracum of Thouars, as at present understood, is 

 confined to those species which have a single stipe to the pollinia, 

 a character which, according to R. A. Rolfe in Dyer's Flora of 

 Ti^opical Africa (7 : 133), is the only absolute one by which An- 

 greecum can be separated from the genera allied to it. In Listro- 

 stachys Reichb. £, the globose pollinia are situated upon a pair 

 of slender stipes distinct from each other or only united at base, 

 while in Mystacidium Lindl.,the pollinia are situated upon a pair 

 of slender stipes which are attached to separate oblong or squam- 

 iform glands.
