    Perennial. Culms arching, or scandent; 150-300 cm long; 10-15 mm diam.; woody; without nodal roots. Culm-internodes terete; smooth, or scaberulous; distally glabrous. Lateral branches dendroid; infravaginal. Bud complement 30-60. Branch complement many; in a clump; thinner than stem. Culm-sheaths deciduous; 17-80 cm long; hairy on margins. Culm-sheath ligule 0.5 mm high; ciliolate. Culm-sheath blade triangular; indistinctly demarcated from sheath; erect; 1.2-2.7 cm long; pubescent. Leaves 3-4 per branch. Leaf-sheaths glabrous on surface; outer margin hairy. Leaf-sheath oral hairs ciliate; 1 mm long. Ligule an eciliate membrane; 0.5-0.6 mm long; pubescent on abaxial surface; truncate. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.15-0.2 cm long; petiole pubescent. Leaf-blades linear; 7.8-20 cm long; 4-8.5 mm wide. Leaf-blade venation without cross veins, or with obscure cross veins. Leaf-blade surface glabrous. Leaf-blade apex attenuate; filiform.
    Inflorescences
    Inflorescence a panicle; exserted, or embraced at base by subtending leaf. Peduncle tipped by a glumaceous appendage. Panicle open; linear; 7-16 cm long. Primary panicle branches appressed, or ascending; 2-3 cm long. Panicle axis angular; scabrous; glabrous. Panicle branches angular; scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 1-4 mm long; smooth, or scaberulous.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; curved; laterally compressed; 5.1-6.5 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 ovate; curved; laterally compressed; 5.1-6.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.4-0.9 mm long; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface pubescent; hairy above. Lower glume apex obtuse. Upper glume ovate; 1-1.8 mm long; without keels; 1-3 -veined. Upper glume lateral veins absent, or obscure. Upper glume surface pubescent; hairy above. 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; 1.6-2.9 mm long; 0.5 length of fertile lemma; chartaceous; 3 -veined; acute; mucronate. Lemma of upper sterile floret ovate; 2.7-4 mm long; chartaceous; acute; mucronate. Fertile lemma ovate; 4.3-5.7 mm long; coriaceous; without keel; 5-7 -veined. Lemma apex acute; mucronate. Palea 4.2-5.3 mm long; 4 -veined. Palea surface scabrous. Palea apex with excurrent keel veins.
    Flowers
    Lodicules 3; 1.8-2.1 mm long; membranous; ciliate. Anthers 3; 2.7 mm long. Stigmas 2.
    Fruits
    Caryopsis with adherent pericarp; apex unappendaged.
