Plants cespitose. Basal rosettes well-differentiated; blades 2-6 cm long, about 1 cm wide, ovate, the uppermost leaves often resembling the lower cauline blades. Culms 15-50 cm, few together, decumbent or ascending, light green, glabrous, slightly fleshy or thickened; fall phase branching mostly near the bases, with sparse branching; nodes appressed-pubescent or glabrous. Cauline leaves 3-4(6); sheaths sometimes overlapping near the bases, glabrous, margins ciliate; ligules almost obsolete, or of 0.2-0.8 mm hairs from a tiny membranous base; blades 1.5-10 cm long, 5-14 mm wide, thick, light green, faintly veined, bases cordate, with papillose-based cilia, margins white, cartilaginous. Primary panicles 4-14 cm, more than 1/2 as wide as long, usually long-exserted. Spikelets 1.4-1.8 mm, broadly obovoid-spherical, usually puberulent, sometimes glabrous. Lower glumes 0.4-0.8 mm, acute to obtuse, upper florets 1.1-1.5 mm, broadly ellipsoid, blunt. 2n = 18.
