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.
