towards the apex, subappressed-sericeous on both surfaces, 
somewhat glabrate above; upper stem-leaves much reduced, 
oblanceolate to linear, entire and bracteiform; inflorescence a 
few-headed corymbose cyme; heads about 1 em. high, radiate; 
involuere campanulate, sparingly calyculate; bracts of the in- 
volucre about 13, linear-attenuate, 7 to 9 mm. long, acute, 
slightly sericeous-tomentulose; ray-flowers 8 to 10, rays yel- 
low; disk-flowers 30 to 35; achenes glabrous.

An herbaceous perennial, at first lightly floecose-tomentu- 
lose throughout, later more or less glabrate; stems erect, 3 
to 7.5 dm. high, simple or branched, striate; basal and lower 
stem-leaves long-petiolate, ovate to obovate or oblong-ob- 
lanceolate, including the petiole 4 to 18 cm. long, 1 to 3 em. 
broad, rounded to obtuse at the apex, erenate-dentate to rather 
sharply serrate, narrowed below into the petiole which usually 
much exeeeds the blade, rather thickish in texture, lightly floe- 
eose-tomentulose on both surfaces in the early stages but soon 
more or less glabrate especially on the upper surface; upper- 
most stem-leaves sessile, oblanceolate to lanceolate, dentate 
to laciniate-pinnatifid, often semiamplexicaul by an expanded 
coarsely toothed base; inflorescence a terminal several to 
many-headed corymbose cyme; heads 8 to 10 mm. high, radi- 
ate; involucre campanulate, calyculate, floccose-tomentulose, 
especially at the base, to essentially glabrous; ray-flowers 10 
to 13, rays yellow; disk-flowers rather numerous, 50 to 75; 
achenes glabrous. |
