Culms ca. 2 m or more, ca. 1 cm in diam.; internodes lower 1/2 flattened above branches, green, ca. 30 cm, initially with a white powdery ring below nodes; supra-nodal ridge weakly elevated; sheath scar flat, initially pubescent. Culm sheaths light green, glabrous except at base; auricles absent or small; oral setae 2 or 3, short; ligule ca. 1 mm, initially ciliolate; blade usually reflexed, lanceolate or linear-lanceolate.

Racemes initially terminating leafy branches, peduncle and base of inflorescence enclosed by leaf sheaths; axis and pedicels glabrous or scabrid along angles. Spikelets linear, 4–7 × ca. 0.5 cm; florets 5–11, lower 2 or 3 sometimes sterile. Glumes 2 or 3, thinner than lemma, initially pubescent, 1st small, 5–7-veined, 2nd and 3rd larger, 9–11-veined; lemma 11–14 × ca. 3 mm, scabrid, initially pubescent, transverse veins distinct, apex acuminate or mucronate; lodicules membranous, thickened at base, 5–7-veined.
