    Inflorescences
    Inflorescence a panicle. Panicle spiciform; linear, or oblong; loose; 2-10 cm long; 0.6-0.8 cm wide. Primary panicle branches accrescent to a central axis; with lateral stumps on axis. Panicle axis with rounded ribs, or angular; scaberulous; glabrous; bearing deciduous spikelet clusters. Spikelets subtended by an involucre. Fertile spikelets sessile; 1 in the cluster. Involucre composed of bristles; oblong; 4-10 mm long; base obtuse. Involucral bristles deciduous with the fertile spikelets; numerous; 16-35 in principal whorl; with longest bristle scarcely emergent; 4-10 mm long; terete; flexible; antrorsely scaberulous; glabrous.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3.5-4.5 mm long; falling entire; deciduous with accessory branch structures.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3.5-4.5 mm long; falling entire; deciduous with accessory branch structures.
    Glume
    Glumes dissimilar; reaching apex of florets; thinner than fertile lemma. Lower glume ovate; 1-2 mm long; 0.33-0.5 length of spikelet; membranous; without keels; 1-3 -veined. Lower glume apex obtuse, or acute. Upper glume ovate, or oblate; 3.5-4.5 mm long; 1 length of spikelet; membranous; without keels; 5-7 -veined. Upper glume apex acute.
    Florets
    Basal sterile florets male, or barren; with palea, or without significant palea. Lemma of lower sterile floret elliptic; 1 length of spikelet; membranous; 5 -veined; acute. Fertile lemma ovate; 3.5-4.5 mm long; membranous; without keel; 5 -veined. Lemma margins flat. Lemma apex acute. Palea membranous.
    Flowers
    Lodicules absent. Anthers 3; 2 mm long; anther tip smooth. Styles connate below.
