Plants erect to spreading or decumbent, 0.5–3 × 0.1–6 dm, villous. Leaves basal or nearly so; petiole 1–4(–7) cm; blade oblanceolate, 1.5–5 × 0.2–0.7(–1) cm, villous. Inflorescences with secondary branches not suppressed except in terminal clusters of involucres, green to reddish; bracts 2, similar to proximal leaf blades only reduced, short-petiolate, becoming linear and aciculate at distal nodes, acerose, 1–5 cm × 2–5(–7) mm, awns absent. Involucres 1, greenish, cylindric, not ventricose, 2.5–4 mm, with white to pinkish, thin scarious margins restricted to basal portion of teeth, not corrugate, thinly pubescent abaxially; teeth spreading, equal, 0.3–0.8(–1) mm; awns uncinate with longer ones 0.7–1.3 mm and anterior one mostly 1–1.3 mm, these alternating with shorter (0.3–0.7 mm) ones. Flowers slightly exserted; perianth bicolored with floral tube white and tepals white to rose, cylindric, 2.5–4 mm, pubescent abaxially; tepals connate 1/4 their length, monomorphic, oblanceolate to narrowly oblong, usually truncate to rounded and erose or denticulate apically, occasionally distinctly cuspidate; stamens 9, included; filaments distinct, 2–3.5 mm, glabrous; anthers pink to red or maroon, oblong, 0.6–0.8 mm. Achenes light brown, globose-lenticular, 3.5–4 mm.
