PERISTERIA Hooker 
Peristeria cerina Lindley in Bot. Reg. 23 (1837) 
t. 19538. 
Cogniaux did not report this rare orchid from Trini- 
dad. It was apparently first collected in 1980 by Broad- 
way who reported it the following year (in Orch. Rev. 
39 (1981) 35), stating that ‘‘this Peristeria seems to be 
only known from the Siparia districts of the Colony, 
where it has been met attached to trees, but is a scarce 
Trinidad plant. ’”’ 
Trinipap: Siparia, April 11, 1930, Broadway 7429 (Herb. Ames 
36523). 
Peristeria pendula Hooker in Bot. Mag. 68 (1836) 
t. 3479. 
This species appears hitherto not to have been reported 
from Trinidad with specimen citation. 
Trinipap: Siparia, April 14, 1916, Broadway s.n. (Herb. Trin. 
7656).

tensis Grisebach F]. Brit. W. Ind. Isl. (1864) 609.
