Stems: caudex absent; aerial flowering stems prostrate to erect, solid, not fistulose, 0.1–0.5 dm, glabrous or glandular and short-hispid. Leaves basal and cauline; basal: petiole 0.05–0.3 cm, hispid, blade linear, (0.3–)1–3(–4) × 0.05–0.3 cm, short-hispid, margins plane or revolute, ciliate; cauline sessile, blade linear, 0.3–2.5 × 0.05–0.3 cm, similar to basal blade. Inflorescences cymose, open to diffuse, 4–25 × 5–35 cm; branches sparsely hispid to puberulent, internodes usually glandular; bracts 3–6, semileaflike, 2–10 × 0.5–2 mm. Peduncles erect, straight, filiform, 0.4–1.5 cm, glabrous. Involucres turbinate, 0.5–1 × 0.4–0.8 mm, glabrous; teeth 4, erect, 0.2–0.4 mm. Flowers 1.5–3.5 mm; perianth white with greenish to reddish midribs, becoming pinkish to rose, glabrous or sparsely pubescent; tepals monomorphic, oblong; stamens included, 0.5–2 mm; filaments usually glabrous.
