Plants perennial; cespitose, usually not dense, hard, or knotty, without rhizomes or stolons. Culms 15-65 cm, erect, geniculate, or decumbent, sometimes rooting at the lower nodes, usually branching from the aerial nodes. Sheaths glabrous or pubescent; ligules 0.2-0.3 mm, membranous, ciliate; blades 5-20 cm long, 1-5 mm wide, bases with papillose-based hairs on the margins, both surfaces glabrous or pubescent. Panicles 4-14 cm, with (3)7-12 branches; branches 10-20 mm, with 2-8 spikelets, extending 4-6 mm beyond the base of the terminal spikelets, apices entire; disarticulation at the base of the branches. Spikelets appressed, all alike, with 1 bisexual and 1 staminate (rarely rudimentary) floret. Glumes glabrous, veins scabrous or strigose; lower glumes 4-7 mm; upper glumes 4-9 mm, mostly glabrous, sometimes scabrous or strigose over the veins, apices acute, unawned or awn-tipped, awns about 1 mm; lowest lemmas 4.5-8 mm, usually glabrous, rarely pubescent basally, 3-awned, awns wide basally, central awns slightly longer than the lateral awns, often flanked by 2 membranous 0.5-1.5 mm lobes; lowest paleas 6-8 mm, bilobed, often shortly 2-awned; anthers 3-5.5 mm, usually orange or yellow, occasionally red or purple; second lemmas 5.5-7 mm, glabrous, 3-awned, central awns 4-10 mm, often flanked by membranous lobes, lateral awns 2-10 mm; second paleas 4-7 mm; anthers smaller than those of the lowest florets; rachillas prolonged beyond the second florets as a short bristle. Caryopses 3-4 mm. 2n = 20, 40, 60.
