Leaf sheaths longer than internodes, overlapping, glabrous or pilose, outer margin ciliate; leaf blades lanceolate, regularly distichous, 5–11 × 0.8–1.4 cm, abaxial surface glabrous to densely pubescent, adaxial surface glabrous or puberulous, margins strongly thickened, base rounded to cordate, apex acuminate; ligule ca. 2 mm. Panicle open, finally ovate, 8–20 cm, glandular; lower primary branches in groups of 2 or 3, upper single, long naked below, scaberulous; pedicels 2 to several times longer than spikelets. Spikelets obovate or subglobose, (1.8–)2–2.2 mm, green or brownish; florets similar; glumes subequal or lower slightly shorter, very broadly ovate, 9–11-veined, glabrous or upper or both pubescent, apex subtruncate but margins incurving; lemmas subleathery, smooth, pilose toward apex especially on margins, and also at base of floret, otherwise glabrous.
