This species is somewhat variable in the degree to which its leaves 
are glabrate, but the specimens are in other respects very consistent. 
In habit, inflorescence, and even in involucre rather strongly suggest-

In some individuals shown by this Bolivian material collected by 
Bang the leaves show a tendency to become cuneate at the base, but 
in others the leaf-base is rounded precisely as in the Peruvian type- 
material of the species. This is clearly a matter of individual varia- 
tion. 
The real E. sordescens DC., with which this plant has been asso- 
ciated as a variety, is a native of eastern Brazil with smaller (about 
25-flowered) heads and ovate leaves 3-nerved from the base, while 
in E. endytum the heads are about 40-flowered and the ovate-oblong 
leaves are pinnately veined.

he placed them at 12 to 19. There is now at the Gray Herbarium a
