    Habit
    Perennial. Rhizomes elongated; leptomorph. Culms 140 cm long; 8.5 mm diam.; woody. Culm-internodes terete; thin-walled; distally glabrous, or pilose. Culm-nodes with distinct supra-nodal ridge; pubescent. Lateral branches dendroid. Branch complement three; with subequal branches. Culm-sheaths glabrous, or pilose; with appressed hairs; glabrous on margins, or hairy on margins; without auricles; glabrous on shoulders, or ciliate on shoulders. Culm-sheath ligule ciliolate. Culm-sheath blade ovate; deciduous; erect, or spreading; scabrid. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs scanty, or lacking. Leaf-sheath auricles absent. Ligule a ciliolate membrane; pubescent on abaxial surface. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 10-20 cm long; 14-26 mm wide. Leaf-blade venation with obscure cross veins. Leaf-blade surface glabrous. Leaf-blade apex attenuate.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; 11-15 cm long; bearing few fertile spikelets; bearing 3-4 fertile spikelets on each. Spikelets ascending, or pendulous; solitary. Fertile spikelets pedicelled. Pedicels 10-30 mm long; puberulous.
    Spikelets
    Spikelets with diminished florets at the apex. Spikelets lanceolate; laterally compressed; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 6 mm long; scaberulous; pubescent; hairy at tip.
    Fertile
    Spikelets with diminished florets at the apex. Spikelets lanceolate; laterally compressed; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 6 mm long; scaberulous; pubescent; hairy at tip.
    Glume
    Glumes two; persistent; similar; shorter than spikelet. Lower glume ovate; 4-6 mm long; chartaceous; 1-keeled; keeled above. Lower glume surface smooth, or scabrous; rough above. Lower glume apex acute. Upper glume lanceolate, or ovate; 5-8 mm long; chartaceous; 1-keeled; keeled above. Upper glume surface smooth, or scabrous; rough above. Upper glume apex acute.
    Florets
    Fertile lemma oblong, or ovate; 13 mm long; chartaceous; without keel. Lemma lateral veins with cross-veins. Lemma surface hispidulous. Lemma margins ciliolate; hairy above. Lemma apex acute, or acuminate. Palea 1 length of lemma. Palea keels approximate; ciliolate; adorned above. Palea surface puberulous; hairy on margins. Palea apex obtuse. Apical sterile florets resembling fertile though underdeveloped.
