    Habit
    Perennial; caespitose. Rhizomes short; pachymorph. Culms arching; 300-1000 cm long; 20-30 mm diam.; woody; without nodal roots. Culm-internodes terete; thick-walled; distally glabrous, or hispid. Culm-nodes glabrous. Lateral branches dendroid; intravaginal. Branch complement several, or many; in a clump; with subequal branches; thinner than stem. Culm-sheaths hispid; hairy throughout; without auricles. Culm-sheath ligule 2 mm high; ciliate. Culm-sheath blade triangular; erect; 5.5 cm long; pubescent. Leaf-sheaths keeled; outer margin glabrous, or hairy. Leaf-sheath auricles erect. Ligule an eciliate membrane; 10-70 mm long; acuminate. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades deciduous at the ligule; lanceolate; 12-28 cm long; 8-23 mm wide; dark green. Leaf-blade midrib prominent beneath. Leaf-blade margins cartilaginous; scaberulous.
    Inflorescences
    Inflorescence a panicle. Panicle open; linear; 25-50 cm long; 1 cm wide. Primary panicle branches ascending; 5-11 cm long. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels scabrous.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; curved; subterete; 6-7.7 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 lanceolate; curved; subterete; 6-7.7 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.3-0.7 mm long; 0.33-0.5 length of upper glume; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume ovate; 0.9-1.2 mm long; 0.1-0.2 length of adjacent fertile lemma; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. 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; 3 mm long; chartaceous; 3 -veined; acuminate. Lemma of upper sterile floret ovate; 3.7-4.8 mm long; chartaceous; acuminate. Fertile lemma ovate; 5.7-6.4 mm long; coriaceous; without keel; 5-7 -veined. Lemma margins involute; covering most of palea. Lemma apex acute. Palea tightly convolute around flower; 1 length of lemma. Palea keels contiguous above a sulcus. Palea apex with excurrent keel veins.
    Flowers
    Lodicules 3; membranous; veined; ciliate. Anthers 3; 3.5-4.1 mm long; yellow. Stigmas 2.
    Fruits
    Caryopsis with adherent pericarp; apex unappendaged.
