Perennials, 3–8 (–12+) cm (usually ± pulvinate). Stems ± erect; internodes 0.1–1 mm, ± scabrellous. Leaves basal and cauline, ± spatulate to oblanceolate, 15–50 (–80) × 2–6 (–11) mm, little, if at all, fleshy, faces ± scabrellous. Heads on scapiform peduncles 30–80 (–120) mm. Involucres ± hemispheric to campanulate, 10–15 mm diam. Phyllaries 14–26 in 2–3+ series, the longer lanceovate to lanceolate, 9–11 mm (l/w = 3–5), apices attenuate, abaxial faces piloso-strigose to strigose. Ray-florets 12–21; corollas white adaxially, laminae 6–12+ mm, glabrous abaxially. Disc-florets 60–80+; corollas 3.5–5 mm. Cypselae 2.5–3.5 mm, faces hairy, hair tips entire; pappi persistent, 16–20+ lanceolate to subulate scales 0.2–0.8 mm (± connate). 2n = 18.
