Leaves basal (withering) and cauline, (1–)2–6 cm; largest blades linear or ± elliptic, ± plane or terete, ± succulent, 0–1-pinnately lobed; lobes 1–2(–5) pairs, remote, ± terete. Heads mostly 1–5(–7) per stem. Peduncles 1–5(–8) cm, glabrous (and ± expanded) distally. Involucres broadly obconic to campanulate. Phyllaries: longest 10–18 mm (surpassed by florets); outer distally tomentulose-puberulent in fruit (proximally glabrous, not stipitate-glandular), apices ± squarrose, blunt, pliant. Florets: corollas (diurnal) dirty-whitish to pinkish, 6–10 mm (± equal to cypsela lengths, anthers exserted); peripheral corollas erect to ascending, actinomorphic, scarcely enlarged. Cypselae 5–9 mm; pappi of 8 scales in 2, abruptly unequal series, longest scales 5–9 mm. 2n = 14.
