    Habit
    Perennial. Culms arching; 100-150 cm long; 3-5 mm diam.; woody. Culm-internodes terete; 5-9 cm long; smooth, or scaberulous. Culm-nodes without obvious supra-nodal ridge. Lateral branches dendroid; extravaginal. Bud complement 20. Branch complement many; in a clump; with subequal branches, or 1 branch dominant; thinner than stem. Culm-sheaths persistent; 4.3-7 cm long; antrorsely scabrous; glabrous on margins. Culm-sheath ligule 0.5 mm high; ciliolate. Culm-sheath blade linear; indistinctly demarcated from sheath; erect; 0.2-0.5 cm long; pubescent; mucronate. Leaves 4-8 per branch. Leaf-sheaths keeled; glabrous on surface; outer margin hairy. Ligule an eciliate membrane. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 4.4-12.2 cm long; 3-8 mm wide. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence a panicle; bracteate at branch bases. Panicle open; linear; 4.5-6.5 cm long. Primary panicle branches appressed; 1-3 cm long. Panicle axis angular, or flat; glabrous. Panicle branches angular; scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1-5 mm long.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 4.8-5.5 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; 4.8-5.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.5-0.7 mm long; 0.1 length of spikelet; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 0.8-1.3 mm long; 0.2 length of adjacent fertile lemma; membranous; without keels; 0-1 -veined. Upper glume primary vein absent, or obscure. Upper glume lateral veins absent. Upper glume apex obtuse.
    Florets
    Basal sterile florets barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret elliptic; 2.6-3.1 mm long; 0.66 length of fertile lemma; chartaceous; 1 -veined; without lateral veins; pubescent; hairy above; hairy on veins; acute; mucronate. Lemma of upper sterile floret elliptic; 2.8-3.3 mm long; chartaceous; pubescent on midvein; acute; mucronate. Fertile lemma ovate; 3.6-4.8 mm long; coriaceous; without keel; 7 -veined. Lemma lateral veins prominent. Lemma surface pubescent; hairy above. Lemma apex acute; mucronate. Palea 3.5-4.8 mm long; 2-4 -veined. Palea surface scabrous. Palea apex with excurrent keel veins.
    Flowers
    Lodicules 3; 0.6-1.4 mm long; membranous; ciliate. Anthers 3. Stigmas 2.
    Fruits
    Caryopsis with adherent pericarp; 3.5 mm long; apex unappendaged. Hilum linear; 1 length of caryopsis.
