Plants 40–200 cm; caudices short, stout. Stems 1–10(–20+), erect or ascending, glabrous throughout or hairy in arrays. Leaves: rosettes present at flowering; basal and proximal cauline tapering to long, winged petioles sheathing stems or nearly so, blades narrowly ovate to oblanceolate, 100–400 × 10–60 mm, thick or fleshy, entire, acute, glabrous; mid to distal cauline usually numerous, sessile, blades lanceolate, 40–60 × 5–10 mm, reduced distally, thick or fleshy, bases sometimes subclasping, margins entire. Heads 20–500, secund, in paniculiform arrays, secund-pyramidal to broadly club-shaped, sometimes leafy proximally, at least proximal branches spreading-recurved, branches and peduncles bracteolate, bracteoles reduced distally. Peduncles 2–3 mm, glabrous or sparsely hairy. Involucres 3–7 mm. Phyllaries in 3–4 series, unequal, lanceolate, margins ciliate, apices acute. Ray florets 8–17; laminae 5–6.2 × 0.4–0.6 mm. Disc florets 10–22; corollas 3–3.2 mm, lobes 0.5–1.2 mm. Cypselae (obconic) 1.1–1.5 mm, moderately strigose; pappi 3.8–4 mm (slightly clavate).
