    Fertile
    Spikelets comprising 4-7 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; compressed slightly; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent; hairy on the margins.
    Glume
    Glumes similar; shorter than spikelet. Lower glume lanceolate; 7-11 mm long; 1 length of upper glume; coriaceous; without keels; 3-7 -veined. Lower glume lateral veins ribbed. Lower glume surface scabrous; rough on veins. Lower glume apex acuminate; muticous, or awned; 1 -awned. Lower glume awn 0.5-1 mm long. Upper glume lanceolate; 7-11 mm long; 0.8-1 length of adjacent fertile lemma; coriaceous; without keels; 3-7 -veined. Upper glume lateral veins ribbed. Upper glume surface scabrous; rough on veins.
