A loosely caespitose perennial on a short branched rhizome, base surrounded by a few cataphylls. Culms 40–70 cm., creeping to ascending, glabrous, nodes dark and glabrous. Leaf sheaths smooth to scaberulous, loosely to densely hairy with bulbous based bristles. Ligule 1–2 mm. long, truncate, erose. Leaf laminae 4–20 × 0.5–1.5 cm., lanceolate to linear, flat, scaberulous, loosely hairy on both surfaces, scabrous along the margin. Inflorescence composed of 7–20 racemes, 4–12 cm. long, patent, often branched, solitary along a well developed common axis. Rhachis triquetrous, scarcely winged, smooth to minutely scaberulous with scabrous margins. Pedicels 2(3)-nate, 0.5–2.5 mm. long, triangular, scabrous, scarcely broadened at the apex, spikeletgroups scattered along the rhachis, often patent. Spikelets 1.8–2.5 mm. long, lanceolate. Inferior glume small, ovate to triangular, sometimes truncate to bifid. Superior glume 1/2–3/4 of the spikelet, oblong triangular, 3-nerved, appressed hairy, hairs fine, hyaline, smooth, acute. Inferior lemma as long as the spikelet, lanceolate, 7-nerved, nerves equidistant, smooth, appressed hairy. Superior lemma somewhat smaller than the spikelet, lanceolate, acute, pale yellow to pale brown, sometimes dark brown or purplish tinged.
