Plants 40–60 (–80) cm (rhizomatous). Leaves mostly cauline (not notably reduced distally); proximal petiolate; blades strongly 3-nerved, ovate, 4–10 cm × 11–30 mm. Heads 1–5, 20–33 mm diam. Peduncles 5–15+ cm. Phyllaries 8–12 × 1.5–3 mm, apices acute. Paleae ± linear, apices acute. Corollas pink, lobes 3.5–7.5 × 0.5–1 mm. Pappi: scale margins serrulate. 2n = 18.


Phenology: Flowering May–Jun.
