Psilochilus macrophyllus was cited from Trinidad by 
Cogniaux as Pogonia macrophylla. Known from Guate- 
mala, northern South America and several of the islands 
in the West Indies, it is obviously a rather rare species 
in Trinidad where it is represented only through one col- 
lection: Sieber 381.

of the flora.

Scaphyglottis modesta is known from the West Indies 
and the northern half of South America. It was not in- 
cluded by Cogniaux in his enumeration of ‘Trinidad spe- 
cies. According to Broadway (in Orch. Rev. 35 (1927) 
20) ‘‘a full-sized plant hangs down with leaf-stems two 
or more feet in length.”
