this and the succeeding species. They differ much in size and perhaps in 
pubescence, and the leaves of this species are, I think, thinner in substance 
and the laciniate leaves less dentate than those of G. Quercifolia. The pe- 
tioles and peduncles afford no certain character. I have for the present 
used Pursh’s description of this species though dissatisfied with it. 
Grows in dry shaded and rocky soils — found in the upper and mountain- 
ous districts of, Carolina and Georgia. 
Flowers July — September.

slightly scabrous ; 
flowers axillary, oppo-

Root perennial, creeping. Stem firmly erect, 3 — 6 feet high, branch- 
ing, obtusely angled, purple, glabrous except near the summit. Upper 
leaves lanceolate, acute, slightly mucronate, with translucent veins, the up- 
per surface and margins, slightly scabrous, the lower leaves pinnatifid, the 
segments acute and toothed, and somewhat scabrous on both surfaces. 
Peduncles about 3 lines long. Calyx when young, pubescent, when old 
glabrous. Corolla about 2 inches long, ventricose, yellow, hairy on the 
inner surface, the border equally 5 cleft. Filaments nearly as long as the 
corolla, very villous at base, the long pair fringed along the back. An- 
thers hairy, bifid, and awned at base. Style as long as the stamens. Stig- 
ma obtuse. Capsule a little compressed at the summit. 
This is probably the G. flava of Walter. 
Grows in dry rich soils, very common. 
Flowers from May to September. >
