    Inflorescences
    Inflorescence a panicle. Peduncle tipped by a glumaceous appendage (treated as sterile spikelets). Panicle capitate; oblong, or ovate; 1-3 cm long; 0.5-1 cm wide. Primary panicle branches accrescent to a central axis; with evident branchlets on axis, or with lateral stumps on axis. Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong.
    Spikelets
    Basal sterile spikelets represented by a single scale; 2 in number; ovate; 1.5-3 mm long. Basal sterile spikelet glumes membranous. Spikelets comprising 2-3 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 4.5-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Sterile
    Basal sterile spikelets represented by a single scale; 2 in number; ovate; 1.5-3 mm long. Basal sterile spikelet glumes membranous.
    Fertile
    Spikelets comprising 2-3 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 4.5-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; reaching apex of florets, or shorter than spikelet. Lower glume ovate; 3-6 mm long; 0.9-1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume ovate; 3-6 mm long; 0.8-1.2 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume apex acuminate.
    Florets
    Fertile lemma elliptic, or oblong; 4-5 mm long; membranous; without keel; rounded except near apex; 3-5 -veined. Lemma surface puberulous. Lemma apex dentate; 3-5 -fid; awned; 1 -awned (with mucronate lobes). Principal lemma awn 0.5-1 mm long overall. Palea 1 length of lemma; 2 -veined. Palea keels pubescent. Palea apex dentate; 2 -fid.
    Flowers
    Anthers 3; 2-2.5 mm long. Stigmas 2; terminally exserted; pubescent. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp; ovoid; 2 mm long; hairy at apex. Hilum elliptic.
