Leaves progressively reduced distally (basal usually withering before flowering); petiolate (petioles winged); blades oblanceolate to spatulate, 4–7 × 1.5–3 cm, bases tapered, margins incised (distal leaves sessile, bractlike). Heads 6–10(–20) in cymiform arrays. Calyculi of 1–5+ linear to subulate bractlets (to 4 mm). Phyllaries ± 13, 6–7 mm, tips green. Ray florets ± 8 (± 13?); corolla laminae 5–6 mm. Cypselae usually hairy (especially on angles), sometimes glabrous. 2n = 40.
