    Habit
    Perennial. Culms erect; 100-150 cm long; wiry. Culm-nodes glabrous. Lateral branches ample. Leaf-sheaths glabrous on surface. Leaf-sheath auricles erect. Ligule a ciliolate membrane; 4-6 mm long; acute. Leaf-blades 20-40 cm long; 4-6 mm wide; stiff; glaucous. Leaf-blade midrib widened. Leaf-blade surface ribbed; scabrous; rough on both sides; glabrous. Leaf-blade margins scabrous.
    Inflorescences
    Synflorescence compound; linear; 20-35 cm long. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; embraced at base by subtending leaf. Spatheole linear. Racemes 1; single; 2.5-3 cm long. Rhachis fragile at the nodes; subterete; ciliate on margins. Rhachis internodes filiform. Rhachis internode tip flat. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels filiform; without a translucent median line; ciliate.
    Sterile
    Companion sterile spikelets well-developed; male; lanceolate; 5 mm long; as long as fertile. Companion sterile spikelet glumes tuberculate. Companion sterile spikelet lemmas enclosed by glumes; muticous.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pubescent; base obtuse; attached obliquely. Companion sterile spikelets well-developed; male; lanceolate; 5 mm long; as long as fertile. Companion sterile spikelet glumes tuberculate. Companion sterile spikelet lemmas enclosed by glumes; muticous.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pubescent; base obtuse; attached obliquely.
    Glume
    Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume elliptic; 1 length of spikelet; chartaceous; without keels; 5-7 -veined. Lower glume surface flat; tuberculate; rough on veins. Lower glume apex obtuse. Upper glume lanceolate; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret hyaline; 0 -veined; without midvein; without lateral veins. Fertile lemma linear; hyaline; without keel; 1 -veined. Lemma apex entire; awned; 1 -awned. Principal lemma awn apical; geniculate; 16-18 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.
