Plants perennial; cespitose, usually stoloniferous. Culms 5-35 cm, erect; nodes villous. Sheaths striate, glabrous; ligules 1-3 mm, often lacerate; blades 3-15 cm long, 1-3.5 mm wide, adaxial surfaces sparsely pilose, hairs papillose-based, margins sparsely pilose basally, with similar hairs. Panicles 2-4 cm; fascicles 5-8 mm. Lateral spikelets with 2(3) staminate florets, or 1 sterile floret; glumes unequal, thick, indurate, and conspicuously fused basally, thinner distally, asymmetrically lobed, scabrous, pale to purplish, bases sometimes spotted with a few dark glands, margins wide, hyaline, awns 1 or more, attached below midlength, equaling or exceeding the central spikelets, antrorsely scabrous; lower glumes wider, more deeply lobed, with longer awn(s) than the upper glumes; anthers 3, 3-3.7 mm. Central spikelets as long as or longer than the lateral spikelets, with 1 pistillate floret; glumes terminating in 1 or more antrorsely scabrous awns. 2n = 36, 72, 74.
