Plant 2 — 4 feet high, nearly glabrous. Leaves alternate, hastate, sin- 
uate, angled and toothed, with a long attenuated base, resembling a winged 
petiole, lateral lobes so abruptly angled at their termination, as frequently 
to appear proemorse. Flowers in loose terminal panicles ; florets purple, 
This plant bears so striking a resemblance to the P. Alba, as to 
render it doubtful whether it ought to be separated from it. It appears 
from the specimens I possess, to be a taller plant, to have its leaves much 
more distinctly hastate, its angles and lobes more acute. 
Grows in the mountains in Pendleton county, S. Carolina. 
Sent to me also from Salem, N. Carolina, by Dr. Schweinitz.
