Stelis trinitensis [Ames apud] Broadway in Orch. Rev. 
34 (1926) 134, sphalm. 
Stelis trinitatis appears to be a very strict endemic at 
Aripo. The type was collected at the ‘‘Heights of Aripo”’ 
by Broadway. Simmonds 230 was found at an altitude of 
2000 feet, “‘by the Caves Trail,’’ and Simmonds 410 grew 
at 1200 feet. The Downs & Aitken collection was made 
in the ‘‘Cave Region.”’ 
The only other species of Ste/is known from Trinidad 
and Tobago is the widespread |S. ophioglossoides (Jacq. )
