Root perennial. Stem three to four feet high, pubescent, sometimes 
nearly glabrous. Leaves oblong-lanceolate, entire, finely pubescent, the 
upper sessile, the lower divided, having two lateral small leaflets near the 
base, which are also lanceolate, and a common petiole near an inch long. 
Flowers axillary and terminal. Exterior involucrum divided to the stem, 
as long as the interior. Florets of the ray about eight, dilated and toothed 
at the summit, bright yellow. 
Grows on the high mountains of Carolina and Virginia. 
Flowers August — October. Pursh. 
Var. Diversifolia. 
Lowest leaves trifoliate with the 
leaflets round, those of the stem 
with the leaflets obovate; the upper- 
most simple, spathulate-lanceolate, 
all entire and with the stem hairy; 
seed nearly round, denticulate, two- 
toothed at the summit. 
This species differs in many respects from the preceding; the stem is 
short, dichotomously divided at the summit. The lowest leaves small, tri- 
foliate, the folioles all orbicular; the next larger with the folioles sometimes 
obovate, sometimes nearly round; the upper spathulate-lanceolate; the 
whole plant instead of being covered with a fine pubescence, is sprinkled 
with long white glandular hairs. Flowers naked, on peduncles, nearly a foot 
long, proceeding from the division of the stem. Calyx and corolla as in 
the preceding variety. Seed nearly round, slightly bidentate, and finely 
toothed along the margins. Chaff of the receptacle very narrow, longer 
than the florets of the disk. 
Collected in the middle country of Carolina by Mr. Whitlow.
