Plants 15–55 cm. Corms globose (sometimes knotty). Stems glabrous. Leaves: basal and proximal cauline 1-nerved, spatulate-oblanceolate to narrowly lanceolate or oblanceolate-linear, (50–)60–100(–220) × 3–8(–15) mm (usually reaching at least level of heads), quickly to gradually reduced distal to midstems, essentially glabrous or sparsely pilose (abaxially), weakly, if at all, gland-dotted. Heads in dense to loose, spiciform arrays. Peduncles 0. Involucres turbinate-campanulate, 7–10 × 6–8(–10) mm. Phyllaries in 3–4(–5) series, oblong, unequal, glabrous, margins with hyaline borders (0.2–0.4 mm wide), ciliolate, apices rounded. Florets 7–13(–17); corolla tubes sparsely pilose inside. Cypselae (2.5–)3.5–5 mm; pappi: lengths 1/3–2/3 or equaling corollas, bristles barbellate. 2n = 20.
