Spiranthes costaricensis has apparently never been re- 
ported from Trinidad, It has probably been confused 
with Spiranthes elata. Vegetatively, these two species 
are similar, even though Spiranthes costaricensis usually 
is somewhat smaller than S. e/ata. The differences in 
flower, however, are such that it should be possible to 
distinguish the two easily. The apical part of the lip is 
transverse and broader than long in Spiranthes elata, 
whereas it is oblong-ovate to suborbicular in S. costari- 
censis. | have seen no Trinidad material which could be 
referred to Spiranthes elata, but Cogniaux cites a Purdie 
and a Crueger collection as representing this species.
