Basal leaves (relatively leathery) sessile; blades linear, 10–15+ × 1–2 mm, margins entire (revolute). Cauline leaves abruptly reduced (linear, bractlike). Heads 1(–2). Peduncles bracteate, tomentose or glabrate. Calyculi conspicuous. Phyllaries 13, purple to deep reddish purple, 6–9+ mm, hairy or glabrescent. Ray florets 0 or 5–8; corolla laminae 4–7 mm. Disc florets 30–40+; corolla tubes 2.5–3.5 mm, limbs 3.5–4 mm. Cypselae 3–3.5 mm, hirtellous; pappi 5–6 mm.
Phenology: Flowering mid Apr–mid May.
