    Perennial. Culms arching, or leaning; pendulous at the tip; 400-1500 cm long; 13-55 mm diam.; woody; without nodal roots. Culm-internodes terete; solid; 25-42 cm long; distally glabrous. Culm-nodes with distinct supra-nodal ridge. Lateral branches dendroid; infravaginal. Branch complement many; in a clump; thinner than stem. Culm-sheaths persistent; 20.5-46.5 cm long; retrorsely scabrous; hairy on margins. Culm-sheath ligule 1-2.5 mm high; ciliate. Culm-sheath blade lanceolate; erect; 9.7-21 cm long; scabrid (below); acuminate. Leaves 4-7 per branch. Leaf-sheaths keeled; striately veined; glabrous on surface; outer margin hairy. Ligule an eciliate membrane; 0.5-1.2 mm long; pubescent on abaxial surface; obtuse. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.2-0.3 cm long. Leaf-blades linear; 17-27 cm long; 3-7 mm wide. Leaf-blade midrib prominent beneath. Leaf-blade venation without cross veins. Leaf-blade surface scabrous; rough adaxially; glabrous. Leaf-blade margins cartilaginous; serrulate. Leaf-blade apex attenuate; filiform.
    Inflorescences
    Inflorescence a panicle; subtended by bracts (1.5-2mm). Peduncle 1.5-9 cm long. Panicle open; linear; 13-19 cm long. Primary panicle branches appressed. Panicle axis angular; scabrous. Panicle branches angular; scabrous. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 7.9-11 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; 7.9-11 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.5-0.7 mm long; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume ovate; 0.5-0.7 mm long; 0.1 length of adjacent fertile lemma; membranous; without keels. 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; 5.3-6.2 mm long; 0.5-0.66 length of fertile lemma; chartaceous; 7 -veined; scabrous; rough above; setaceously attenuate. Lemma of upper sterile floret ovate; 6.2-7.1 mm long; chartaceous; scabrous; setaceously attenuate. Fertile lemma ovate; 7.6-7.9 mm long; coriaceous; without keel; 9 -veined. Lemma surface scabrous; rough above and between veins. Lemma apex acute. Palea 7.3-7.6 mm long; 6 -veined.
    Flowers
    Lodicules 3; 0.9-1.1 mm long; membranous; ciliate. Anthers 3. Stigmas 2.
