Plants 25–85 cm. Corms globose. Stems glabrous. Leaves: basal and proximal cauline 1-nerved, lance-linear to linear, 50–150 × 2–5 mm, gradually or abruptly reduced distally, essentially glabrous (proximal margins sparsely ciliate). Heads in dense, racemiform to spiciform arrays (sometimes strongly to weakly secund, especially if branches reclining, internodes 1–5 mm). Peduncles 0 or (ascending) 1–6(–10) mm. Involucres cylindro-turbinate, (7–)8–9 × 3.5–4 mm. Phyllaries in 3–4 series, ovate-oblong, oblong, or oblong-lanceolate (inner 7.5–10 × 1–1.8 mm), strongly unequal, essentially glabrous, margins with hyaline borders (lacking at apices), ciliolate, apices (inner and middle, sometimes outer) rounded to blunt, involute-cuspidate to short-acuminate.
