Leaves mostly cauline (basal abruptly withering); proximal cauline blades usually linear-oblong, rarely oblanceolate to obovate, 4–10(–20) × 2–6 mm, reduced distally, margins entire, faces hispid, minutely glandular. Heads 1(–3) per main branch, (–20–30 in later season on wiry, brittle branches). Involucres 4–5 × 6–8 mm. Phyllaries in (2–)3–4 series, glabrous or outer sparsely hispid, minutely glandular. Ray florets 20–40(–50); corollas white to pink or purplish, without abaxial midstripe, 5–9 mm, laminae not coiling or reflexing. Disc corollas 3.5–4 mm (throats slightly white-indurate and inflated).
