Plants 22–50 cm. Corms globose to subglobose. Stems glabrous. Leaves: basal and proximal cauline 3–5-nerved (parallel veins evident, not persistent), elliptic-lanceolate, 80–150(–180) × 3–10(–12) mm (largest toward midstem), gradually or slightly reduced distally, glabrous, weakly gland-dotted. Heads borne singly or (2–5) in loose, racemiform to spiciform arrays. Peduncles 3–25 mm (each head subtended by broad, foliaceous bracts longer than involucres). Involucres cylindro-campanulate, 12–17 × 8–14 mm. Phyllaries (loose to spreading) in 5–7 series, narrowly lanceolate (outer, usually longer than inner, foliaceous) to broadly oblong or narrowly oblong-lanceolate, usually glabrous, sometimes sparsely puberulent, margins without hyaline borders, apices acuminate to acute or cuspidate. Florets 18–25; corolla tubes glabrous inside (lobes adaxially hispid). Cypselae 5.5–8 mm; pappi: lengths ± equaling corollas, bristles plumose.
