Plants 20–45+ cm. Stems proximally usually piloso-hirsute (or lanate, hairs 5–8+ mm, usually curled and tangled), sometimes nearly glabrous, distally piloso-hirsute (hairs 1–2+ mm) and stellate-pubescent. Leaves: basal (2–) 3–8+, cauline (0–) 3+; blades elliptic or spatulate to oblanceolate, lanceolate, or lance-linear, (35–) 50–120 (–200+) × 10–25 (–40+) mm, lengths 2–5 (–10+) times widths, bases ± cuneate, margins usually entire, rarely toothed, apices obtuse to acute, faces (proximal leaves) piloso-hirsute (to lanate, hairs 1–3+ mm; distal leaves often ± glabrate). Heads 3–12 (–20+) in corymbiform arrays. Peduncles usually stellate-pubescent and stipitate-glandular. Calyculi: bractlets 3–5+. Involucres campanulate, (7–) 8–9 mm. Phyllaries 12–15+, apices rounded to acute, abaxial faces stellate-pubescent and/or stipitate-glandular. Florets 12–15+; corollas yellow, 7–9 mm. Cypselae columnar, 2.2–4 mm; pappi of (40–) 60–80, white or stramineous bristles in 2+ series, 4–5+ mm.
