Plants 25–75 cm. Corms globose. Stems glabrous. Leaves: basal and proximal cauline 1-nerved, linear, 40–100 × 1–2 mm, even-sized or gradually reduced distally, essentially glabrous, gland-dotted (proximal margins sparsely ciliate). Heads (widely spaced, stems evident) in loose, spiciform arrays. Peduncles 0. Involucres turbinate-cylindric, (11–)12–15 × 5–7 mm. Phyllaries in 5–6(–7) series, broadly oblong to lanceolate-oblong, strongly unequal, glabrous, margins without hyaline borders, finely ciliolate, apices obtuse, rounded, or truncate, sharply involute-apiculate.
