ORCHIDACEyE 



In general habit not unlike E. purpurea. The extraordinarily 

 long peduncle in Lindley's specimen of Matthews 1877 from 

 Peru is a distinguishing character of this species. The sac of the 

 labellum as figured by Lindley on the type sheet is bulbous.

This species is closely allied to E. major and to E. Killipii. 

 From the latter species it differs markedly in the calli on the 

 anterior wall of the sac, the lowermost ones, being very much 

 reduced.
