Subshrubs or herbs, much-branched and matted, not scapose, (1–)5–15 × 2–8 dm, glabrous, rarely floccose. Stems spreading to erect, with persistent leaf bases, up to 1/4 height of plant; caudex stems matted; aerial flowering stems erect to spreading, usually stout, solid or hollow, occasionally fistulose, (0.8–)2–6 dm, glabrous, rarely floccose. Leaves basal or sheathing up stems 0.5–3 dm; petiole 5–20 cm, floccose; blade oblong to oblong-ovate, (1.5–)3–10 × (1–)2–6 cm, densely white-tomentose abaxially, tomentose to floccose to subglabrous and greenish adaxially, margins plane, occasionally crisped. Inflorescences subcapitate to cymose, (5–)20–100 × 4–50 cm; branches usually dichotomous, glabrous, rarely floccose; bracts 3–8 or more, leaflike, oblong to oblong-ovate, and 5–20 × 5–10 mm proximally, scalelike, triangular, and 2–6 mm distally. Peduncles absent. Involucres 1–3 per cluster, turbinate-campanulate to campanulate, (4–)5–7 × 3–6 mm, floccose to subglabrous; teeth 5–8, erect, 0.3–0.6 mm. Flowers 2.5–3.5 mm; perianth white to pink, rose, or red, glabrous; tepals connate proximal 1/4, monomorphic, oblong-obovate; stamens exserted, 3–6 mm; filaments pilose proximally. Achenes brown, 2.5–3 mm, glabrous.
