retuse. Labellum triangular-ovate, about as broad as long, 
2.2-3 mm. long, thicker on the margins than in the typical 
form. Column about 2.2-2.8 mm. long at the back. 
Epidendrum Sanchoi var. exasperatum is represented in 
our herbarium by a large series of Costa Rican specimens. 
They show some vegetative variation, as does the species, 
but they have flowers which generally differ from those of 
the type form in the characters specified. In view of the 
great variability of the species and because of the several 
close allies, it seems advisable to give merely a varietal 
status to this Epidendrum.
