Perennial. Stems ascending to erect, usually branched, glabrous or with a few sparse hairs below, 4-60-(150) cm tall. Lvs all basal, oblanceolate to linear-oblanceolate, usually shallowly to deeply pinnatifid, rarely simple and toothed, (2)-4-20-(40) × (0.5)-0.8-4-(9) cm, with moderately dense pale strigose hairs. Stem bracts few, minute. Capitula turbinate to campanulate. Involucral bracts linear-lanceolate with narrowly acute apex, 6-15 mm long at flowering, up to 20 mm long at fruiting, glabrous except for a row of strigose hairs on midrib (the distal hairs dark), herbaceous or with narrow scarious border. Florets yellow, c. 11/2× length of involucre. Achenes dark brown, scabrid, fusiform, beaked, 8-16 mm long, sometimes the outer achenes not or shortly beaked and then shorter.
