Perennial, usually densely caespitose. Culms swollen and bulb-like at base, suberect, 15–45 cm tall. Leaves mostly basal, somewhat glaucous; blade setaceous, flat or folded; sheaths all smooth, glabrous; blades never hairy; ligule of cauline leaves long (usually c. 3 mm), acute. Panicle oblong-ovoid, rather lax, often suffused purple. Spikelets 4–6 mm, 3- or 4-flowered; glumes and lemmas acute.
