Ecuapor: epiphyte, edge of forest between Paramos Minza Chica 
and Minza Grande, Province of Tunguragua, at 3800 meters altitude, 
‘flower pale transparent green, central part of the lip thick and 
whitish,’’ April 5, 1939, Penland & Summers 333 (Type in Herb. Ames 
No. 57891). 
Epidendrum vesicicaule is allied to HZ. piperinum Lindl., 
IE. Peperomia Reichb.f. and FE. peperomiordes Schltr. 
(all of which are very similar), but differs in its larger size, 
in the shape of the leaves, and in the structure of the 
flowers. 
The specimen (Lehmann 8338) cited by Kriinzlin in 
Engler’s Bot. Jahrb. 26 (1899) 462, as Wpidendrum Pep- 
eromia Reichb.f. may belong here, but the flowers of the 
specimen of that number inthe Ames Herbarium are not 
in condition to warrant a sure diagnosis. 
The specific name is in allusion to the bladder-like 
leaf-sheaths which cover the stem.
