    Fertile
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 10.5-12 mm long; breaking up at maturity; disarticulating below each fertile floret.

Lower glume surface scabrous; rough on veins. Lower glume apex acute, or acuminate. Upper glume lanceolate; 5-6.5 mm long; 0.5 length of adjacent fertile lemma; coriaceous; with membranous margins; without keels; 3-5 -veined. Upper glume surface scabrous; rough above. Upper glume apex acute, or acuminate.
    Florets
    Fertile lemma lanceolate; 9-10.5 mm long; coriaceous; 5 -veined. Lemma surface puberulous. Lemma apex acute; awned; 1 -awned. Principal lemma awn straight, or curved; 5-10 mm long overall.
