Spikelets 0.8–1.4 mm long, reddish-brown; inferior glume 2/5–3/5 the length of the spikelet, lanceolate, nerveless, glabrous, acute to acuminate at the apex; superior glume as long as the spikelet, ovate to ovate-elliptic, 1-nerved, smooth or hispidulous, acute at the apex; lemma a little shorter than the spikelet, ovate; anthers 3, 0.2–0.5 mm long.

Panicle 4.5–16 cm long, narrowly elliptic; branches in a succession of whorls, smooth, with elongated viscid glandular patches, the spikelets 6–30 per branch, evenly distributed in the distal part.
