This species most nearly approaches the Guatemalan E. pyenoce- 
phaloides Robinson but the correspondence is not so exact that the 
two cannot be readily distinguished by the longer pedicels, umbelli- 
form inflorescence, and some minor details of pubescence, ete. Both 
of these species differ from the common, variable, and widely dis- 
tributed E. pycnocephalum Less. in having distinctly larger heads 
and more acute intermediate and inner involucral scales. 
E. amyqpatinum Lam. Encye. ii. 408 (1786). In a preliminary 
treatment of the Eupatoriums of Ecuador, Proc. Am. Acad. liv. 345 
(1918), the writer drew attention to the fact that this species, widely 
distributed in the American tropics, seemed never to have been col- 
lected in, or at least not to have been reported from, Ecuador. The 
opinion was ventured that it was pretty certain to be found there. 
It is now possible to record the Ecuadorian occurrence of the plant 
thus: Between Loja and Portovelo, 3-6 Oct., 1918, J. N. Rose,
