Root perennial. Stem voluble, striate, pubescent, climbing fifteen to 
twenty feet high. Leaves opposite, cordate, conspicuously acuminate, an- 
gled an<l somewhat hastate at base, pubescent, on petioles about an inch long. 
Flowers in paniculate corymbs, axillary and terminal. Involucrum com- 
posed of four equal leaves, and a fifth exterior and smaller, all linear-lanceo- 
late, acuminate, hairy. Corolla tubular, a little longer than the calyx, pale 
purple, slightly fragrant. Stamens very short. Style almost twice as long 
as the corolla, two-cleft. Seed oblong, striate, slightly angled when young, 
glandular. Pappus hairy. Receptacle naked, dotted. 
The Synonyme of Walter, quoted under the preceding species, probably 
belongs to this. The genus itself is scarcely distinct from Eupatorium. 
Grows very abundantly in damp soils.
