    Fertile
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 1 length of upper glume; coriaceous; much thinner on margins; without keels; 3-5 -veined. Lower glume surface smooth, or scabrous. Lower glume apex entire, or with a unilateral tooth; setaceously attenuate. Upper glume lanceolate; 0.75 length of adjacent fertile lemma; coriaceous; with membranous margins; without keels; 3-5 -veined. Upper glume surface smooth, or scabrous. Upper glume apex entire, or with a unilateral tooth; setaceously attenuate.
    Florets
    Fertile lemma lanceolate; coriaceous; 5 -veined. Lemma surface puberulous. Lemma apex acute; awned; 1 -awned. Principal lemma awn 5-12 mm long overall; 1 length of lemma. Palea keels scabrous; with 15-30 enations per keel. Apical sterile florets resembling fertile though underdeveloped.
