Epidendrum equitantifolium Ames nom. nov. 
Epidendrum equitans Lindl. in Bot. Reg. (1838) Misc. 
44, non Ruiz & Pav. (1798). 
There are two species which have passed under the 
name Epidendrum equitans. The older one was described by 
Ruiz and Pavon from Peruvian material. For the Central 
American species, now known to range from Mexico to 
Panama, I propose the new name Epidendrum equitanti¬ 
folium.
