    Habit
    Perennial. Rhizomes elongated; leptomorph. Culms erect; 800-1000 cm long; 30-40 mm diam.; woody. Culm-internodes terete; thin-walled; mid-green, or purple. Lateral branches dendroid. Branch complement three, or several; in a horizontal line. Culm-sheaths coriaceous; glabrous, or pilose; with dark brown hairs; truncate at apex; without auricles; glabrous on shoulders. Culm-sheath ligule 1 mm high; ciliolate. Culm-sheath blade lanceolate; acuminate. Leaves cauline; 3-5 per branch. Leaf-sheaths glabrous on surface, or puberulous. Leaf-sheath oral hairs setose. Ligule a ciliolate membrane; 1-2 mm long; truncate. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate, or elliptic; 15-25 cm long; 25-35 mm wide. Leaf-blade surface puberulous; densely hairy; hairy abaxially. Leaf-blade apex acuminate.
    Inflorescences
    Synflorescence bractiferous; fasciculate; with spathaceous subtending bracts; bracts 25-40 mm long; without axillary buds at base of spikelet; with ultimate bract subtending a compact bracteolate fascicle of spikelets; prophyllate below lateral spikelets. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 50-60 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 8 mm long; sparsely hairy.
    Fertile
    Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 50-60 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 8 mm long; sparsely hairy.
    Glume
    Glumes one the lower absent or obscure; persistent; shorter than spikelet. Upper glume lanceolate; 20-22 mm long; chartaceous; without keels. Upper glume apex acute.
    Florets
    Fertile lemma oblong; 13-25 mm long; chartaceous; without keel; 11-13 -veined. Lemma lateral veins with cross-veins. Lemma surface scabrous. Lemma apex acuminate. Palea 12-16 mm long; coriaceous; 11-13 -veined. Palea keels ciliolate. Palea surface pubescent; hairy on back. Palea apex with excurrent keel veins. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 3; lanceolate; 6 mm long; veined; ciliate. Anthers 3; 9 mm long. Stigmas 3.
    Fruits
    Caryopsis with adherent pericarp.
