This widely distributed species has gone under the name of 
E. paniculatum Schrad. in the West Indies, &. Szuclairut

This species was first discovered in Arizona, then in Sonora, 
and now in Guatemala. The Arizona material, from which — 
the original description was drawn, proves to be not at all 
representative. The Sonoran and Guatemalan specimens are 
more or less pubescent, with lanceolate (in the Guatemalan 
specimens very narrowly so) long acuminate leaves with tapet 
ing base and sharply toothed in the middle, loose almost dif- 
fuse inflorescence, and corolla more often pink than white. 
EUPATORIUM POPULIFOLIUM HBK.—Volcan Tecuamburro, 
Depart.Santa Rosa, alt. 6,000", February 1893, Heyde & Lut

Evidently a very variable species in foliage, the leaves vary” 
ing from lanceolate with attenuate base to very broad ovate 
with either truncate or cordate base. Heyde & Lux 2,84% 
from San Felipe, Depart. Retalhulen, alt. 2,050", April 1892+ 
as the usual glabrous achenes, and is reported as a showy 
virgate plant 14" high.
