Culm-nodes with distinct supra-nodal ridge. Lateral branches dendroid; infravaginal. Bud complement 20-25. Branch complement many; in a clump; with subequal branches, or 1 branch dominant; thinner than stem. Culm-sheaths 4.5-11 cm long; glaucous. Culm-sheath ligule 3-4 mm high; ciliolate. Culm-sheath blade triangular; cordate; demarcated but persistent; erect; 4-9 cm long. Leaves 8-12 per branch. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs scanty. Ligule an eciliate membrane; 1-1.5 mm long; truncate, or obtuse. Collar with external ligule. Leaf-blade base broadly rounded; with a brief petiole-like connection to sheath; petiole 0.1 cm long; petiole glabrous. Leaf-blades lanceolate; 4.6-8 cm long; 8-12 mm wide. Leaf-blade venation without cross veins, or with obscure cross veins. Leaf-blade surface glabrous.
    Inflorescences
    Inflorescence a panicle; subtended by a spatheole (two); embraced at base by subtending leaf. Spatheole lanceolate; 2.4-3.2 cm long. Panicle contracted; elliptic; secund; 2-4 cm long. Primary panicle branches spreading; 1-1.5 cm long. Panicle axis angular; scabrous. Panicle branches angular; pubescent; with prominent pulvini. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 1-2 mm long; scabrous.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 8.8-10.3 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; 8.8-10.3 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.1-0.7 mm long; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 0.2-1.3 mm long; membranous; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 3-4.6 mm long; chartaceous; 3 -veined; acute; mucronate. Lemma of upper sterile floret ovate; 3.5-5.1 mm long; chartaceous; acute; mucronate. Fertile lemma ovate; 7.8-9.4 mm long; coriaceous; without keel; 7-9 -veined. Lemma margins ciliolate; hairy above. Lemma apex acute; mucronate. Palea 8.2-9.6 mm long; 4-6 -veined. Palea keels contiguous above a sulcus. Palea surface pubescent; hairy on back; hairy above. Palea apex with excurrent keel veins.
    Flowers
    Lodicules 3; 1.5-2 mm long; membranous; ciliate. Anthers 3; 4.6-5.2 mm long. Stigmas 2.
    Fruits
    Caryopsis with adherent pericarp; apex unappendaged.
