    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; erect, or drooping; bilateral; 10-20 cm long. Rhachis flattened; scabrous on margins. Spikelet packing broadside to rhachis. Rhachis internodes linear. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
    Fertile
    Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 11-16 mm long; 1 length of upper glume; coriaceous; much thinner on margins; without keels; 5-7 -veined. Lower glume surface scabrous. Lower glume apex entire, or with a unilateral tooth; acuminate. Upper glume lanceolate; 11-16 mm long; 1.2 length of adjacent fertile lemma; coriaceous; with scarious margins; without keels; 5-7 -veined. Upper glume surface scabrous. Upper glume apex entire, or with a unilateral tooth; acuminate.
    Florets
    Fertile lemma lanceolate; 9-13 mm long; coriaceous; 5 -veined. Lemma surface pubescent. Lemma apex acute; awned; 1 -awned. Principal lemma awn ascending, or spreading; 3-22 mm long overall. Palea 8-10 mm long. Apical sterile florets resembling fertile though underdeveloped.
