Inflorescence an ovate open panicle 6–12 cm. long, the branches sometimes simple and reduced to racemes.. Spikelets 5–10-flowered, broadly elliptic, 5.4–6.8 mm. long; glumes slightly unequal, rounded on the back, subacute and sometimes mucronulate, shorter than or slightly exceeding the lowermost lemmas, the lower 3-nerved, lanceolate to elliptic-oblong, 2.8–5 mm. long, the upper 3–4-nerved, elliptic-oblong, 3.6–5.7 mm. long; lemmas prominently 3-nerved with the lateral nerves as long as the lemma, broadly elliptic, 3–4.3 mm. long, membranous, densely asperulous, the tip broadly rounded to truncate and often mucronulate; palea densely asperulous like the lemma..
