North Easton, Massachusetts, June 14th, 1928 
SEPARATION OF THREE SPECIES OF 
EPIDENDRUM. 
Side lobes of labellum much broader near the apex than near the base, i.e. 
spatulate Epidendrum Mooreanum Rolfe. 
Side lobes of the labellum not broader near the apex, but as broad or broader 
near the base; 
Veins of libellum verrucose or papilose, midlobe rounded or 
obtuse Epidendrum alanjense Ames, 
Veins of labellum not verrucose or papilose; midlobe commonly 
acute or acuminate Epidendrum ramonense 
NOTE: Epidendrum meliosma Reichb. f. appears to come only from Mexico.The Costa 
Rican material , Brenes 266, referred to E, meliosma by Schleehter is 
clearly referable to E. ramonense. 
Answer to question about the difference between Epidendrum ochraceum and E. 
Mooreanum. 
Middle lobe of labellum similar to lateral lobes, not larger; inflor- 
escens racemose. Flowers small £. ochraceum. 
Middle lobe of labellum different from the lateral lobes, markedly larger; 
inflorescens paniculate, flowers large E. Mooreanum.
