Herbs, matted, scapose, 0.2–1(–1.3) × 0.5–5 dm, glandular-hairy, greenish. Stems matted, with persistent leaf bases, up to 1/5 height of plant; caudex stems matted; aerial flowering stems scapelike, weakly erect to erect, slender, solid, not fistulose, 0.1–0.9(–1.1) dm, densely glandular-hairy. Leaves basal, fasciculate in terminal tufts; petiole 0.4–2 cm, tomentose, sometimes also glandular; blade oblanceolate or broadly elliptic to oval, 0.4–2.5 × (0.15–)0.25–1.6 cm, densely white-tomentose and glandular on both surfaces or densely white-tomentose abaxially and greenish-tomentose adaxially, margins plane. Inflorescences capitate, 0.6–1.5 cm; branches absent; bracts 3, scalelike, triangular, 1–3.5 mm. Peduncles absent. Involucres 3–6 per cluster, turbinate to campanulate, (2.5–)3–5(–6) × 2.5–4(–6) mm, rigid, glandular and sparsely hairy; teeth 5–8, erect, 0.7–1.4 mm. Flowers 2–4 mm; perianth bright yellow to reddish yellow, occasionally cream, glabrous or glandular; tepals connate proximally, monomorphic, obovate or oblong; stamens exserted, 3–5.5 mm; filaments glabrous or sparsely pilose proximally.
