An excellent photograph of the type of the Peruvian 
Epidendrum moyobambae, together with the description, 
shows that it includes the concepts heretofore represented 
by the Central American Z. subpatens Schltr. and £. 
benignum Ames. At most there are very slight differ- 
ences in measurements, but none in form. 
Epidendrum amazonicum is said to have erect-spreading 
or subspreading racemes, whereas they vary from sub- 
spreading to pendent in the other forms of this concept: 
otherwise the plant is nearly identical. 
It is evident that /pidendrum patens Sw. differs wide- 
ly from all forms of J. moyobambae because of its pan- 
iculate inflorescences and much smaller flowers. ‘These 
characters are well set forth by Fawcett & Rendle (Fl. 
Jam. 1 (1910) 89). 
This species extends from Guatemala (/), through 
Costa Rica and Panama to Trinidad, Colombia, Brazil 
and Peru.
