Culm-nodes without obvious supra-nodal ridge; pubescent. Lateral branches dendroid; infravaginal. Bud complement 5-8. Branch complement several; in a clump; with 1 branch dominant; thinner than stem. Culm-sheaths persistent; 14-26 cm long; retrorsely scabrous; hairy on margins. Culm-sheath ligule 0.5 mm high. Culm-sheath blade lanceolate; erect; 3-8.5 cm long; scabrid. Leaves 4-8 per branch. Leaf-sheaths glabrous on surface; outer margin glabrous. Ligule an eciliate membrane; 2-4.5 mm long; glabrous on abaxial surface; obtuse. Collar with external ligule. Leaf-blade base asymmetrical; with a brief petiole-like connection to sheath; petiole 0.2-0.8 cm long; petiole glabrous. Leaf-blades oblong; 9-28 cm long; 24-58 mm wide. Leaf-blade midrib evident. Leaf-blade venation with obscure cross veins. Leaf-blade surface glabrous. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence a panicle; bracteate at branch bases; subtended by an unspecialized leaf-sheath, or an inflated leaf-sheath; embraced at base by subtending leaf. Panicle capitate; globose; dense; 2-3 cm long. Panicle axis angular, or flat; glabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 2-4 mm long; glabrous.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 8-9.5 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 oblong; laterally compressed; 8-9.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 3-5 mm long; membranous; without keels; 3-5 -veined. Lower glume surface scabrous; inner surface pubescent. Lower glume apex attenuate; awned; 1 -awned. Lower glume awn 6-10 mm long. Upper glume ovate; 4-5 mm long; 0.5 length of adjacent fertile lemma; membranous; without keels; (3-)5 -veined. Upper glume surface scabrous; inner surface pubescent. Upper glume apex attenuate; awned; 1 -awned. Upper glume awn 6.9-8 mm long.
    Florets
    Basal sterile florets barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 8-9.5 mm long; 1.1 length of fertile lemma; chartaceous; 5-7 -veined; acute; mucronate, or awned. Awn of lower sterile floret 1-1.9 mm long. Lemma of upper sterile floret ovate; 8-9.5 mm long; chartaceous; scabrous (above); acute; mucronate. Fertile lemma ovate; 7.7-8.9 mm long; coriaceous; without keel; 7-9 -veined. Lemma surface scabrous; rough above. Lemma apex acute; mucronate. Palea 7-8.8 mm long; 4 -veined. Palea surface scabrous. Palea apex pubescent; with excurrent keel veins.
    Flowers
    Lodicules 3; 1-2 mm long; membranous. Anthers 3; 4-5 mm long. Stigmas 2.
    Fruits
