    Inflorescences
    Inflorescence composed of racemes. Racemes numerous; borne along a central axis; closely spaced; paucilateral; 3-15 cm long. Central inflorescence axis 20-50 cm long. Spikelet packing broadside to rhachis; crowded; irregular. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 2-6 basal sterile florets; 12-20 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; compressed strongly; 15-35 mm long; falling entire. Rhachilla internodes obscured by lemmas.
    Fertile
    Spikelets comprising 2-6 basal sterile florets; 12-20 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; compressed strongly; 15-35 mm long; falling entire. Rhachilla internodes obscured by lemmas.
    Glume
    Glumes similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 1 length of upper glume; chartaceous; 1-keeled; 3 -veined. Lower glume primary vein scabrous. Lower glume apex acute; muticous, or mucronate. Upper glume lanceolate; 0.66-1 length of adjacent fertile lemma; chartaceous; 1-keeled; 5 -veined. Upper glume primary vein scabrous. Upper glume apex acute; muticous, or mucronate.
    Florets
    Basal sterile florets similar; barren; without significant palea. Lemma of lower sterile floret similar to fertile lemma; ovate; 7-11 mm long; coriaceous; 1-keeled; 3-9 -veined; acute. Fertile lemma ovate; 7-11 mm long; coriaceous; keeled; 3-9 -veined. Lemma midvein scabrous. Lemma margins eciliate, or ciliolate. Lemma apex acute; muticous, or mucronate. Palea 1 length of lemma; 2 -veined. Palea keels winged; scabrous. Apical sterile florets resembling fertile though underdeveloped.
