Leaves glabrous or sparsely hairy (basal withered by flowering); proximal and mid blades lanceolate to narrowly elliptic, entire, serrate, or irregularly toothed or lobed; distal blades lanceolate to linear, entire. Heads 20–200+ per plant, in paniculiform arrays. Peduncles 2–14 cm, moderately to densely hairy. Involucres globoid, 5–11 × 5–12(–13) mm. Phyllaries (connate proximally) moderately to densely hairy.
