Plants 30–90 cm. Stems proximally usually glabrous, sometimes piloso-hirsute (hairs 3–8+ mm) and/or stellate-pubescent, distally usually glabrous. Leaves: basal 0 (–2), cauline 6–12+; blades elliptic or oblanceolate to lanceolate, 30–80 (–150) × 6–25 (–35) mm, lengths 3–6+ times widths, bases cuneate, margins usually toothed, sometimes denticulate or entire, apices acute to acuminate, faces glabrous or piloso-hirsute (hairs 1–4+ mm). Heads (6–) 12–50+ in corymbiform to paniculiform arrays. Peduncles usually glabrous, sometimes stipitate-glandular. Calyculi: bractlets 8–13+. Involucres campanulate to cylindric, 6–7 mm. Phyllaries 8–13+, apices acute to acuminate, abaxial faces usually glabrous, sometimes stipitate-glandular. Florets 8–20 (–30); corollas ochroleucous to yellow, 5–8 mm.
