Lateral branches dendroid; intravaginal. Bud complement 6-12. Branch complement several to many; in a clump; thinner than stem. Culm-sheaths 10.6-18 cm long; glabrous. Culm-sheath ligule 1-2 mm high; ciliolate. Culm-sheath blade triangular; indistinctly demarcated from sheath; erect; 1.6-6.5 cm long; scabrid. Leaves 6-11 per branch. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 1-2.5 mm long; truncate, or obtuse. Collar with external ligule; glabrous. Leaf-blade base broadly rounded; with a brief petiole-like connection to sheath; petiole 0.2-0.4 cm long. Leaf-blades linear, or lanceolate; 13-29 cm long; 10-18 mm wide. Leaf-blade venation with distinct cross veins. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence a panicle; exserted, or embraced at base by subtending leaf. Panicle open; lanceolate; 11-29 cm long; contracted about primary branches. Primary panicle branches 3-9 cm long; bearing spikelets almost to the base. Panicle axis smooth, or scaberulous. Panicle branches angular; scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 1.5-4 mm long; scabrous.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 5.6-7.5 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 elliptic; laterally compressed; 5.6-7.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.6-1 mm long; membranous; without keels; 0-1 -veined. Lower glume lateral veins absent. Lower glume surface scabrous. Lower glume apex acute. Upper glume ovate; 0.9-1.6 mm long; without keels; 1 -veined. Upper glume surface scabrous. 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; 4.2-5 mm long; chartaceous; 3-5 -veined; pubescent; hairy above; acute. Lemma of upper sterile floret ovate; 5.3-6.3 mm long; chartaceous; pubescent (above); acute. Fertile lemma ovate; 6-7.1 mm long; coriaceous; without keel; 7-9 -veined. Lemma surface pubescent; hairy above. Lemma apex acute. Palea 5.6-6.2 mm long; 4 -veined. Palea surface pubescent; hairy on back.
    Flowers
    Lodicules 3; membranous; ciliate. Anthers 3. Stigmas 2.
    Fruits
    Caryopsis with adherent pericarp; sulcate on hilar side; apex unappendaged.
