Plants perennial; not rhizomatous, not stoloniferous, densely tufted. Basal branching intravaginal. Culms 2-60 cm, terete, bases bulbous. Sheaths closed for about 1/4 their length, lowest sheaths with swollen bases; ligules 1-6 mm, smooth or scabrous, obtuse to acute; blades (0.5)1-2.5 mm wide, flat, thin, lax, soon withering. Panicles (0.8)2-10 cm, ovoid, loosely contracted; nodes with 2-5 branches; branches usually ascending, infrequently spreading, terete, usually smooth or sparsely scabrous, rarely moderately scabrous. Spikelets 3-7 mm, laterally compressed, some or all bulbiferous; florets (2)3-7, forming a bulblet, sometimes the basal 1-2 florets normal. Glumes shorter than the adjacent lemmas, distinctly keeled, keels scabrous; lower glumes 3-veined; calluses terete or slightly laterally compressed, glabrous or dorsally webbed, hairs wrinkled; lemmas normal or leaflike, normal lemmas 2-4 mm, distinctly keeled, glabrous throughout or the keels and marginal veins villous, intercostal regions glabrous or puberulent, leaflike lemmas thickened at the base, bladelike distally; paleas scabrous, keels often softly puberulent at midlength; anthers 3, (0.6)1.2-2 mm, sometimes aborted late in development, sometimes not developed.
