Dioecious. Plants 3–14 cm (bases woody). Stolons none. Basal leaves absent at flowering. Cauline leaves linear-lanceolate to cuneate-oblanceolate, 11–35 × 2–6 mm, acute, not flagged (apices acute), faces gray-pubescent. Heads 3–25 in corymbiform to paniculiform arrays. Involucres: staminate 6–8 mm; pistillate 6–8 mm. Phyllaries distally red to pink, light-brown, or white. Corollas: staminate 3–4.5 mm; pistillate 5–6 mm. Cypselae 2–2.5 mm, pubescent and papillate; pappi: staminate 6–7 mm (capillary); pistillate 6–7 mm. 2n = 28.
