    Inflorescences
    Inflorescence a panicle; bearing juvenile spikelets at emergence. Panicle open; oblong; dense; 30-50 cm long; 10-20 cm wide. Primary panicle branches profusely divided; naked below. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 3-11 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 7-16 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 0.5-1 mm long; bearded; obtuse. Floret callus hairs 0.5 length of lemma.
    Fertile
    Spikelets comprising 1 basal sterile florets; 3-11 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 7-16 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 0.5-1 mm long; bearded; obtuse. Floret callus hairs 0.5 length of lemma.
    Glume
    Glumes persistent; similar; shorter than spikelet; similar to fertile lemma in texture; gaping. Lower glume lanceolate to ovate; 0.7-1 length of upper glume; membranous; without keels; 3-5 -veined. Lower glume apex cuspidate. Upper glume lanceolate to ovate; 3-5 mm long; 0.4-0.6 length of adjacent fertile lemma; membranous; without keels; 3-5 -veined. Upper glume apex cuspidate.
    Florets
    Basal sterile florets male, or barren; with palea; persisting on inflorescence. Lemma of lower sterile floret similar to fertile lemma; elliptic; 7-8 mm long; 1 length of fertile lemma; membranous; 3-7 -veined; acuminate. Fertile lemma lanceolate; 8-9 mm long; membranous; without keel; 1-3 -veined. Lemma apex acuminate. Palea 0.66 length of lemma; 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
