Plants 20–100 cm. Corms subglobose (often knotty, densely fibrous-rooted). Stems sparsely to densely puberulent, puberulent-villous, or strigoso-puberulent. Leaves: basal and proximal cauline 1-nerved, narrowly oblanceolate to spatulate-lanceolate, 90–150 (–220) × 4–17 (–24) mm, gradually reduced distally to near midstem, then abruptly reduced, linear or narrowly lanceolate, ascending to nearly erect, bractlike, sparsely to densely puberulent, ± glanddotted. Heads (4–21) in open, racemiform arrays (terminal heads sometimes maturing first and larger). Peduncles usually (5–) 8–15 (–30) mm. Involucres campanulate to turbinate-campanulate, 10–15 × 13–18 mm. Phyllaries in (3–) 4–5 series, oblong-obovate to oblong-spatulate, strongly unequal, essentially glabrous, margins with (purple) hyaline borders, erose to lacerate or irregular, apices broadly rounded to truncate. Florets 30–70; corolla-tubes glabrous inside. Cypselae 5–7 mm; pappi: lengths ± equaling corollas, bristles barbellate. 2n = 20.
