Stem two to three feet high, erect, striate, almost furrowed near the sum- 
mit, very villous. Leaves large, oval-lanceolate, nearly acute, hairy and 
slightly scabrous on the upper surface, almost villous underneath; the upper 
ones nearly sessile, the lower attenuated into a sheath-like petiole, four to 
six inches long, serrate. Flowers in a long, terminal, somewhat crowded 
raceme, composed of small erect branches. Scales of the involucrum ob- 
long, slightly pubescent. Florets of the ray six to eight, yellow. Seed 
glabrous. 
Specimens of this plant collected by Dr. McBride are marked as I have 
described them. In specimens sent from Pennsylvania by Dr. Muhlenberg, 
the leaves are nearly glabrous, only scabrous along the margins, and more 
entire. 
Grows in the mountains of Carolina. 
Flowers August — September.
