sembling each other in general habit and in the shape of the leaves. 
Of the two Z&. pallens approaches most nearly the remaining mem-

This species is well represented in American herbaria and the 
following more recent collections are referred to it: Pringle 2439, 
Seler 1751, Duges 476a, Conzatti 117. It has usually been dis- 
tributed as Vernonia paniculata DC., which, in fact, it may be.
