and Costa Rica where it is found on trees in humid forests 
at high elevations, occasionally up to 2600 meters. alti- 
tude. On the contrary, D. trichocarpa is widespread and 
rather common in the West Indies, with a few stations 
in Mexico, Guatemala and Costa Rica. & Dichaea inter- 
media occurs only in Mexico and Guatemala, the north- 
ern limit of the area of distribution for both D.squarrosa 
and JD. trichocarpa. 
Lindley (in Ann. & Mag. Nat. Hist. ser. 8, 1 (1858) 
333) reported D. squarrosa from Cuba, ‘‘Monte Verde: 
woods; on trees,”” collected by C. Wright. We have seen 
no material of this species from the West Indies. It is 
quite likely that this report was based on an erroneous 
determination of a specimen of D. trichoearpa.
