Ligule 1–2 mm. long, truncate, erose. Leaf laminae 3–12 × 0.1–0.5 cm., linear, flat, scaberulous on both surfaces, with a few bulbous based bristles on the superior surface, near the base, scaberulous along the margin. Inflorescence composed of (2)4–8 racemes, (3)6–12 cm. long, erect, (2)3–4(5) in a inferior whorl, sometimes a second, superior whorl of 2–3 racemes. Rhachis triquetrous, broadly winged, up to 0.7 mm. wide, smooth to scaberulous with scabrous margins. Pedicels 2-nate, 0.3–3 mm. long, triangular, scabrous, scarcely widened at the apex. Spikelets (1.8)2.1–2.8 mm. long, ovate-oblong. Inferior glume short, triangular, sometimes truncate or even slightly bifid. Superior glume 1/3–2/3 of the spikelet, ovate to oblong triangular, 3-nerved, appressed hairy, hairs fine, smooth, acute. Inferior lemma as long as the spikelet, ovate-oblong, 7-nerved, nerves scabrous, especially the subcentral and submarginal nerves, central zone often broad, appressed hairy.
