    Inflorescences
    Inflorescence composed of racemes; embraced at base by subtending leaf. Racemes 1; single; bilateral; 6-15 cm long; bearing few fertile spikelets; bearing 2-3 fertile spikelets on each. Rhachis flattened; pubescent on surface (sparsely); scabrous on margins. Spikelet packing broadside to rhachis. Rhachis internodes oblong; 10-15 mm long. Spikelets solitary. Fertile spikelets pedicelled, or sessile. Pedicels oblong; 0-1.5 mm long.
    Spikelets
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 20-25 mm long; breaking up at maturity; disarticulating below each fertile floret. Spikelet callus glabrous; base truncate. Rhachilla internodes definite; 2-3 mm long.
    Fertile
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 20-25 mm long; breaking up at maturity; disarticulating below each fertile floret. Spikelet callus glabrous; base truncate. Rhachilla internodes definite; 2-3 mm long.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume elliptic; 4-6 mm long; 0.6-0.8 length of upper glume; coriaceous; without keels; 3-5 -veined. Lower glume primary vein scabrous. Lower glume lateral veins ribbed. Lower glume surface scabrous. Lower glume apex acuminate; muticous, or awned; 1 -awned. Lower glume awn 0-4 mm long. Upper glume elliptic; 6-8 mm long; 0.6-0.8 length of adjacent fertile lemma; coriaceous; without keels; 5-7 -veined. Upper glume lateral veins ribbed. Upper glume surface scabrous.
