FERTILE SPIKELETS Spikelets comprising 5–9 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 14–22 mm long; 4–7 mm wide; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; similar. Lower glume lanceolate; 1.5–3 mm long; coriaceous; without keels; 3 -veined. Lower glume surface scabrous. Lower glume apex acuminate. Upper glume lanceolate; 3–4.5 mm long; coriaceous; without keels; 3–4 -veined. Upper glume surface scabrous. Upper glume apex acute, or acuminate.

FLORETS Fertile lemma lanceolate; 9–10 mm long; coriaceous; 5 -veined. Lemma surface asperulous, or scaberulous. Lemma apex acuminate; awned; 1 -awned.
