    [GB]
    Habit
    Perennial. Culms erect; 50-100 cm long; 3-5 mm diam.; woody; without nodal roots. Culm-internodes terete; thick-walled; 1.5-13.5 cm long; distally pruinose and pubescent. Culm-nodes swollen; without obvious supra-nodal ridge. Lateral branches dendroid; extravaginal; spreading. Bud complement 30-60. Branch complement many; in a clump (triangle of 5-6 rows). Culm-sheaths persistent; 3.4-9.4 cm long; glabrous; glabrous on margins; without auricles. Culm-sheath ligule 0.5 mm high. Culm-sheath blade triangular; demarcated but persistent; erect; 0.9-2.5 cm long. Leaves 4-7 per branch. Leaf-sheaths tight; pubescent. Ligule an eciliate membrane; 0.2-0.5 mm long; truncate. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.02-0.05 cm long. Leaf-blades linear; 0.85-2 cm long; 1-2 mm wide; coriaceous; stiff. Leaf-blade venation without cross veins. Leaf-blade surface glabrous.
    Inflorescences
    Inflorescence a panicle; embraced at base by subtending leaf. Panicle contracted; linear; 1-1.5 cm long. Primary panicle branches appressed. Panicle axis pubescent. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1-3 mm long; pubescent.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; subterete, or dorsally compressed; compressed slightly; 4.7-5.5 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 ovate; subterete, or dorsally compressed; compressed slightly; 4.7-5.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume oblong; 0.4-0.8 mm long; 0.75 length of upper glume; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume surface pubescent. Lower glume apex obtuse. Upper glume oblong; 0.6-1.2 mm long; 0.15 length of adjacent fertile lemma; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume surface pubescent. Upper glume apex obtuse.
    Florets
    Basal sterile florets similar; barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 2.9-4 mm long; 0.5-0.66 length of fertile lemma; chartaceous; 1-5 -veined; without lateral veins, or distinctly veined; pubescent; hairy above; acute. Lemma of upper sterile floret ovate; 2.9-4 mm long; 1.2-1.5 length of lower sterile floret; chartaceous; pubescent; acute. Fertile lemma ovate; 4.5-5.5 mm long; coriaceous; without keel; 5-7 -veined. Lemma surface pubescent; hairy above. Lemma apex acute; mucronate. Palea 4.5-5.3 mm long; 1 length of lemma; 4 -veined.
    Flowers
    Lodicules 3; membranous. Anthers 3; 2.5-2.7 mm long. Stigmas 2.
    Fruits
    Caryopsis with adherent pericarp; apex unappendaged.
