A shrub three to five feet high, with the branches erect, virgate, angled, 
and very glabrous. Leaves alternate, subsessile, acutely toothed towards 
the summit, glabrous, pale green. Heads of flowers sessile, axillary, much 
more scattered than in the preceding species. Scales of the involucrum 
somewhat obtuse. Pappus of the sterile florets short, of the fertile very long. 
Grows in damp pine barrens, along the sea coast of Carolina, but never 
I believe in brackish soils.
