Plants (12–) 25–48 (–55) cm. Corms subglobose to depressed hemispheric. Stems glabrous. Leaves: basal scalelike (usually withering before flowering), cauline 1-nerved, mostly linear, 12–20 (–230) × 1.2–3 (–4.5) mm, gradually reduced beyond midstem, essentially glabrous (margins ciliate). Heads borne singly or (2–10) in subcorymbiform arrays. Peduncles (5–) 12–40 mm. Involucres campanulate-turbinate, 10–19 (–23) × (8–) 10–17 (–21) mm. Phyllaries in ± 3–4 series, (green or purple) lanceolate to linear-oblong, unequal, essentially glabrous or sparsely pilose, margins with or without hyaline borders, ciliate, apices long to short-acuminate. Florets (11–) 14–21 (–25); corolla-tubes glabrous inside. Cypselae (3.5–) 5–7 mm (glabrous); pappi: lengths ± 1/2–2/3 corollas, bristles barbellate.


Phenology: Flowering Jun–Jul(–Aug).
Habitat: Open, grassy areas of dolomitic glades
Elevation: 50–200 m
