Root perennial. Stem about twelve to eighteen inches high, simple, gla- 

 brous, furrowed, not fistulous. Leaves much longer than those of the pre- 

 ceding species, similar but distinctly decurrent, more slightly denticulate. 

 Flower solitary, terminal. Involucrum many leaved, in two series; the 

 exterior (eighteen) subulate, a little hairy at the summit, expanding, finally 

 erect, (are these to be considered as scales belonging to the florets of the 

 ray?) Florets of the ray eighteen to twenty, cuneate, yellow, pubescent on 

 the outer surface, three-cleft at the summitj of the disk very numerous, with 

 tJie border five-cleft. Stamens a little longer than the corolla. Style two- 

 cleft; stigma somewhat capitate. Seeds cylindric, glabrous. Pappus about 

 eight-leaved, leaves membranaceous, awned, fimbriate. Receptacle convex, 

 glabrous, dotted. 



Grows in damp soils — along the head branches of Cooper River. ^ Vu 

 Macbride. In wet pine barrens, Chatham and Bryan counties, Georgia. 



Flowers March — April.

As fimbrlata, the name applied to one of these plants by Michaux is de- 

 rived from a generic character applicable to both, and heleniura not ap- 

 propriate, I have taken the liberty of distinguishing these two species by 

 the names given to them by Dr. Macbride, when many years ago he first 

 pointed them out to me as distinct, though hitherto confounded.
