Leaf-blades 10-25 cm long; 1-2.5 mm wide. Leaf-blade midrib conspicuous. Leaf-blade surface glabrous; hairless except near base. Leaf-blade margins scabrous; tuberculate-ciliate; hairy at base.
    Inflorescences
    Synflorescence compound; dense. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; embraced at base by subtending leaf. Spatheole lanceolate. Peduncle pubescent above. Racemes 2-5; paired, or digitate; 2-3 cm long. Rhachis fragile at the nodes; pubescent on surface; ciliate on margins. Rhachis internodes filiform. Rhachis internode tip transverse; cupuliform; with simple rim. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels filiform; 1.7-2.2 mm long; ciliate; with 1-1.5 mm long hairs.

    Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; 3-4.7 mm long; shorter than fertile; separately deciduous.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4-4.8 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pilose; base obtuse; inserted. Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; 3-4.7 mm long; shorter than fertile; separately deciduous.
    Fertile

    Glume
    Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate; 1 length of spikelet; membranous; 2-keeled; keeled laterally. Lower glume intercarinal veins absent. Lower glume surface flat. Upper glume lanceolate; membranous; 1-keeled; 3 -veined. Upper glume lateral veins obscure. Upper glume muticous.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; hyaline. Fertile lemma lanceolate; 2 mm long; hyaline; without keel; 0 -veined. Lemma apex entire; muticous. Palea absent or minute.
