1. Cordifolia. E. 
Stem about three feet high, finely pubescent, almost tomentose near the 
summit. Lower leaves opposite, cordate, acuminate, dentate, triplinerved, 
finely pubescent, particularly on the under surface, on petioles about an inch 
long ; upper leaves frequently alternate, obtuse at base. Flowers not nu- 
merous, moderately large, in a terminal paniculate corymb. Involucrum 
many leaved, many flowered, (forty to fifty) ; the interior leaves linear-lan- 
ceolate ; the exterior linear, almost setaceous, loosely attached to the sum- 
mit of the peduncle. Corolla tubular, five-cleft at the summit, pale purple. 
Stamens shorter than the corolla, attached to the tube. Style much longer 
than the corolla, two-cleft. Stigmas linear, obtuse. Seed long, angular, 
striate, a little hairy towards the summit. Receptacle slightly convex, naked, 
conspicuously dotted. Pappus hairy, pale purple, a little scabrous, as long 
as the corolla. 
This plant which in its artificial characters is closely allied to the Eupato- 
rium, differing principally in size and number, in its general aspect, beais more 
resemblance to the Vernonia. I have named it in commemoration of Dr. 
John Brickell, of Savannah, w r ho at one period of his life paid much atten- 
tion to the botany of this country, and made known to Dr. Muhlenberg, 
Fraser and others, many of its undescribed plants. 
Grows on the sides of hills in the western districts of Georgia. 
Flowers August — September.
