Plants usually cespitose, sometimes stoloniferous, nodes of the stolons often pilose. Culms 10-75 cm, erect or depressed-decumbent; cauline nodes glabrous or slightly pubescent. Sheaths compressed, mostly glabrous, margins ciliate; ligules 0.2-0.4 mm; blades 4-15 cm long, 1.5-6 mm wide, flat, mostly glabrous, margins with papillose-based cilia. Panicles terminal and axillary, 5-11 cm overall, rachises to 3 cm, with 2-7 branches; branches 2-9(12) cm, spreading or ascending. Spikelets 1.6-2.2(2.8) mm, ovoid or ellipsoid, obtuse to acute. Upper glumes and lower lemmas scarcely extending beyond the upper florets, 2-veined, margins sparsely pilose, apices obtuse to subacute; upper lemmas and paleas 1.6-2.1 mm long, 0.5-0.7 mm wide. Caryopses 1.5-1.8 mm, gray. 2n = 20, 40, 80, 100.
