Plants 20–90 cm. Corms globose, sometimes depressed or elongate. Stems minutely puberulent-hirtellous (hairs spreading to slightly deflexed) or glabrous. Leaves: basal and proximal cauline 1-nerved, narrowly oblanceolate to linear-oblanceolate, 40–120 × 2–7 mm, gradually or abruptly reduced distally (continuing as linear, mostly 10–40 mm bracts), hispidulous-hirtellous or glabrous, weakly, if at all, gland-dotted (glandular hairs not evident, proximal margins sometimes ciliate). Heads in dense, racemiform to spiciform (strongly secund) arrays. Peduncles 0 or (ascending) 1–8 mm. Involucres cylindric, 11–15 × 4–7 mm. Phyllaries in 3–4 series, mostly oblong to oblong-oblanceolate, unequal, essentially glabrous, margins with hyaline borders, apices acute (sometimes with mucros or apicula). Florets 3–6; corolla tubes pilose inside. Cypselae 3–4.5 mm; pappi: lengths ± equaling corollas, bristles barbellate.
