front, with a short falcate-triangular tooth on either side 
of the rostellum, about 5 mm. long at the back, extended 
into ashort excavated foot. Anther semiglobose, with a 
bidentate membranaceous tip. Pollinia four, strongly 
complanate, obliquely semiovate. 
This species is very similar to Scaphyglottis longicaulis 
S. Wats. (S. unguiculata Schltr.), but has a dissimilar 
lip. It also appears to be closely allied to two South 
American species. It differs from the Colombian 5S. 
stricta Schltr. in having shorter stems, narrower leaves 
and a prominently armed column. It varies from the 
Peruvian S. Huebnert Schitr. in having consistently 
larger flowers with narrower segments and a differently 
proportioned lip.
