Epidendrum Storku Ames was described from a 
plant collected by H. E. Stork 460, south of Cartago, 
Costa Rica. The stems are up to 17.5 em. high, the leaves 
2—-5.5 cm. long, 7-18 mm. wide. The mid-lobe of the 
lip is about as broad as long, triangular-acute at the apex. 
The lamina of the lip is broader than long, 7-11 mm. 
long, 13.5-16 mm. broad. 
Epidendrum simulacrum Ames. The type is from 
the Province of Chiriqui, Panama, Powell 298. It is a 
plant 19-24 cm. tall with oblong leaves about 4 cm. long 
and 1 cm. wide and rather small flowers. The mid-lobe 
of the lip is much as in #1. Storku, but the lamina of the 
labellum is about as broad as long, 5-6 mm. long, 5-6 
mm. broad. 
The transition from the typical form of EH. difforme 
to var. firmum, the transition from var. firmum to var. 
Storku, and again the transition from var. Storki to var. 
simulacrum is clearly shown by the material which we 
have examined. Allowance being made for these inter- 
grades, three rather constant variants from the typical 
form may be detected. 
Other species which belong to the general alliance, 
but which have constant differences sufficient to set them 
apart as distinct species are Mpidendrum pudicum Ames, 
E.. Barbeyanum Krinzl. (E.Amparoanum Schitr.) and 
an undescribed species collected by C. W. Powell in 
Panama.
