Panicle axis angular; glabrous. Spikelets solitary, or subtended by an involucre (a few spikelets at base of spike). Fertile spikelets sessile. Involucre composed of bristles; 2-10 mm long. Involucral bristles deciduous with the fertile spikelets; few; 1 in principal whorl; terete; flexible; antrorsely scaberulous; glabrous.
    Spikelets

    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4.5-5 mm long; falling entire; deciduous from the base, or with accessory branch structures.
    Glume
    Glumes shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.25-0.33 length of spikelet; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume ovate; 0.5 length of spikelet; membranous; without keels; 3 -veined. Upper glume apex entire, or dentate; 3 -fid; obtuse.
    Florets
    Basal sterile florets male, or barren; with palea. Lemma of lower sterile floret oblong; 1 length of spikelet; membranous; 5-7 -veined; pubescent; entire, or dentate; 3 -fid; obtuse. Fertile lemma lanceolate; 4.5-5 mm long; chartaceous; without keel; 5 -veined. Lemma margins flat. Lemma apex obtuse. Palea 1 length of lemma; chartaceous.
