This species in the note accompanying the original description 

 is compared with E. secunda Ames, a Mexican species that is 

 well characterized among its allies by the general structure of the 

 labellum, the apical part being' reduced to a crenate margined 

 semiorbicular lobe. In E. Lehmannii the tip of the labellum is 

 also much less developed than is usual in the genus, the terminal 

 lobe being obtusely angled on each side and mucronate in the 

 middle. E. secunda would seem to differ from E. Lehmannii 

 very markedly in having within the sac, near the base, twelve 

 elongated processes.

I have been unable to place this species satisfactorily. It 

 resembles E. secunda Ames in the foliage but is distinct in the 

 raceme and in the terminal lobe of the labellum. E. stictophylla 

 (Schltr.) Ames is a very closely related species. 



Erythrodes lunifera (Schltr.) Ames comb. nov. Physurus lu-

In the lunate terminal lobe of the labellum and in the foliage 

 not unlike E. chicharrasensis Ames, but with the lip-lobes nar-
