Leaves: Basal leaves oblanceolate, densely stiff-hairy, toothed or pinnately cut, 3-35 cm long, 5-70 mm wide; stem leaves mostly lacking, represented by minute bracts.
Flowers: Heads with strap-shaped flowers, several in a terminal, flat-topped inflorescence; involucres 10-15 mm tall, at flowering, up to 25 mm in fruit, 2-4 cm wide; involucral bracts graduated, bristly-hairy or glabrous; ray flowers yellow.
Fruits: Achenes nerved on the beak with minute projections, 4-7 mm long, inner ones with a well-developed beak shorter or longer than the body; pappus double, the inner ones of feathery bristles, the outer ones shorter and usually merely finely-barbed.

A very shade-intolerant, submontane to montane, European forb introduced to Pacific, Cordilleran, and Atlantic North America.
