    Inflorescences
    Inflorescence a panicle. Panicle contracted; oblong; 3-6 cm long; 1.5-2 cm wide. Primary panicle branches bearing 1-3 fertile spikelets on each lower branch. Panicle axis pubescent. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets

    Fertile
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 6-8 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume

Lower glume lateral veins absent. Lower glume apex obtuse, or acute. Upper glume ovate; 2.5-3 mm long; 0.33 length of adjacent fertile lemma; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex obtuse, or acute.
    Florets

Lemma of lower sterile floret ovate; 0.66 length of fertile lemma; chartaceous; purple; 3 -veined; pubescent; hairy above; acuminate; muticous, or mucronate. Lemma of upper sterile floret ovate; 6-8.5 mm long; 1.5 length of lower sterile floret; chartaceous; pubescent; acuminate; muticous, or mucronate. Fertile lemma ovate; 6-8 mm long; coriaceous; purple; without keel; 9-10 -veined. Lemma lateral veins with cross-veins. Lemma surface pubescent. Lemma apex obtuse; muticous, or mucronate.
    Flowers
