Panicle open (1), or contracted (1).

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets, or 2 fertile florets (1); with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 2.5–2.75–3 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.7 length of upper glume; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface without pits. Lower glume apex acute. Upper glume ovate; 0.3–0.4–0.5 length of adjacent fertile lemma; 1-keeled; 1–3 -veined. Upper glume apex acute.

FLORETS Fertile lemma ovate; chartaceous; keeled; wingless; 3 -veined. Lemma surface smooth (1), or scaberulous (1); unwrinkled; without grooves; glabrous (1), or pubescent (1). Lemma apex acute; muticous (1), or mucronate. Palea 1 length of lemma; 1–2 -veined; 1-keeled. Palea surface glabrous (1), or pubescent (1).
