Leaf laminae 4–13 × 0.3–0.8 mm., linear, flat, scaberulous on both sides, with a few bulbous based bristles near the base, scabrous along the margin. Inlforescence composed of 2–9 racemes, 6–12 cm. long, in 1 or 2-more superposed whorls, sometimes a few solitary along the short common axis. Rhachis triquetrous, winged, up to 1.0 mm. broad, smooth with scabrous margins. Pedicels 2-nate, 0.5–2.5 mm. long, triangular, scabrous, scarcely broadened at the apex. Spikelets 2.7–3.4 mm. long, oblonglanceolate. Inferior glume c. 0.5 mm. long, ovate to oblong triangular, often somewhat truncate. Superior glume 2/3–3/4 of the spikelet, oblong triangular, 3-nerved, appressed hairy, hairs very fine, smooth, acute. Inferior lemma as long as the spikelet, oblong-lanceolate, 7-nerved, nerves smooth or nearly smooth, central zone often very broad, appressed hairy, sometimes also with bristle-hairs, rarely glabrous.
