Culms 30-100 cm, slender, erect or geniculate; fall phase freely branching from all nodes, reclining from masses of branchlets and numerous reduced, ciliate blades and secondary panicles; nodes conspicuously bearded with retrorse hairs. Sheaths usually glabrous, lowermost sheaths sometimes sparsely pubescent, occasionally with whitish spots between the veins, ciliate along the margins; blades 5-14 cm long, 5-14 mm wide, thin, spreading to reflexed, glabrous on both surfaces, bases with few to many papillose-based cilia. Panicles 5-12 cm, well-exserted, dense. Spikelets 1.5-1.8 mm, usually glabrous, rarely slightly pubescent. Lower glumes usually less than 14 as long as the spikelets; upper glumes usually shorter than the lower lemmas; upper florets 1.3-1.6 mm long, 0.6-0.8 mm wide, subacute. 2n = 18.
