Lower leaves oblong-cuneate and often toothed or lobed, upper ones linear and entire, sometimes all under 1/4 inch., sometimes those in the middle of the stems 1/2 in. long.

Achenes muricate. Pappus of 1 to 4 rigid barbed awns about 1 line long and 1 or more very short ones, all hirsute at the base, the total number varying from 4 to 8" (Bentham, 1866; p. 504).
