Root perennial. Stem two to three feet higfy, simple, hirsute, somewhat 
viscid. Leaves of the root large, sessile, expanding, somewhat viscid ; 
strongly nerved ; of the stem one or two pair small, opposite, ovate, sessile, 
the smaller ones alternate, one at the base of each peduncle. Invo - 
lucrum with the leaves arranged in a single series, hirsute, lanceolate. 
Florets of the ray twelve to fifteen ; of the disk numerous, all yellow. An- 
thers as long as the florets of the disk. Style a little longer, two-cleft.

on all of the seeds. 
In this species I have not seen any trace of filaments in the florets of the 
ray. 
Grows in damp pine barrens.
