Culm-nodes swollen; with distinct supra-nodal ridge. Lateral branches dendroid; intravaginal. Bud complement 1, or 3. Branch complement several; in a clump; thinner than stem. Culm-sheaths persistent; 4-5 cm long; 4-5 times as long as wide; chartaceous; glabrous. Culm-sheath ligule 0.5 mm high; entire. Culm-sheath blade lanceolate; deciduous; erect; 2.5-3.3 cm long; glabrous on surface. Leaves 3-9 per branch. Leaf-sheaths keeled; striately veined; glabrous on surface; outer margin hairy. Ligule an eciliate membrane; 0.2-0.5 mm long; truncate. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.1-0.15 cm long. Leaf-blades erect; linear; 3-8 cm long; 2-2.5 mm wide; stiff. Leaf-blade midrib keeled beneath. Leaf-blade venation prominent; with 2-4 secondary veins; without cross veins. Leaf-blade surface glabrous. Leaf-blade margins cartilaginous; scabrous.
    Inflorescences
    Inflorescence a panicle. Panicle open; linear; secund; 4-11 cm long. Primary panicle branches appressed; 1-2 cm long. Panicle branches angular; glabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 2-8 mm long; glabrous.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 5.7-6.4 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 5.7-6.4 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.3-0.8 mm long; membranous; without keels; 0-1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume ovate; 0.4-1.2 mm long; without keels; 0-1 -veined. Upper glume primary vein absent, or obscure. Upper glume lateral veins absent. Upper glume apex obtuse.
    Florets
    Basal sterile florets barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 2.7-3.6 mm long; chartaceous; 3 -veined; pubescent; hairy at apex; ciliate on margins; fringed above; acute. Lemma of upper sterile floret ovate; 3-4 mm long; chartaceous; pubescent (at apex); ciliate on margins; fringed above; acute. Fertile lemma ovate; 5.3-5.4 mm long; coriaceous; without keel; 5-9 -veined. Lemma surface pubescent; hairy above. Lemma margins ciliate; hairy above. Lemma apex acute. Palea 4.9-5.4 mm long; 4 -veined. Palea surface pubescent; hairy above.
    Flowers
    Lodicules 3; 0.8-1.4 mm long; membranous; veined; ciliate. Anthers 3; 2.7-3.4 mm long. Stigmas 2. Ovary glabrous.
    Fruits
