Plants perennial; rhizomatous, rhizomes elongate, scaly, scales not imbricate. Culms 35-150 cm tall, 1-3 mm thick, branching, decumbent, sprawling, rooting at the nodes, terminal portions erect. Sheaths scabrous; ligules 0.5-1 mm; blades 7-30 cm long, 5-15 mm wide, spreading to slightly ascending, both surfaces usually scabrous. Panicles 10-30 cm, terminal, also axillary, exserted or enclosed at maturity, spreading on exserted panicles, usually 2 or more branches at the lowest nodes, 1 at the upper nodes; branches 4-10 cm, the lower 1/3 naked, spikelets imbricate. Spikelets (4)4.2-6.5 mm long, 1.3-1.7 mm wide, elliptic. Lemmas and paleas usually ciliate on the keels and margins, glabrous or puberulent elsewhere; anthers 3, 1.5-2(3) mm in chasmogamous spikelets, 0.4-0.7 mm in cleistogamous spikelets. Caryopses 2-3.5 mm, asymmetrically pyriform to obovoid, whitish to dark brown. 2n = 48.
