    Fertile
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 6-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume linear, or lanceolate; 7-10 mm long; 1 length of upper glume; coriaceous; without keels; 3-5 -veined. Lower glume lateral veins ribbed. Lower glume surface scabrous; rough on veins. Lower glume apex acute; mucronate, or awned; 1 -awned. Lower glume awn 0.2-2 mm long. Upper glume lanceolate, or oblong; 7-10 mm long; 0.7-0.8 length of adjacent fertile lemma; coriaceous; without keels; 3-5 -veined. Upper glume lateral veins ribbed. Upper glume surface scabrous; rough on veins. Upper glume apex acute; mucronate, or awned; 1 -awned. Upper glume awn 0.2-2 mm long.
    Florets
    Fertile lemma lanceolate; 9-12 mm long; coriaceous; keeled; keeled above; 5 -veined. Lemma surface scaberulous; rough generally. Lemma apex acute; awned; 1 -awned. Principal lemma awn 2-4 mm long overall. Palea 0.8-0.9 length of lemma. Apical sterile florets resembling fertile though underdeveloped.
