    Habit
    Perennial; caespitose. Rhizomes short; pachymorph. Culms erect; reed-like; 100-200 cm long; 4 mm diam.; woody. Culm-internodes terete. Lateral branches lacking. Leaves mostly basal. Leaf-sheaths longer than adjacent culm internode; glabrous on surface. Leaf-sheath auricles erect. Ligule a ciliate membrane; 16-25 mm long. Leaf-blade base tapering to the midrib. Leaf-blades erect; deciduous at the ligule; aciculate, or lanceolate; 30-44 cm long; 12-22 mm wide; stiff. Leaf-blade surface glabrous. Leaf-blade apex abruptly acute.
    Inflorescences
    Inflorescence a panicle. Panicle open; ovate; 25-65 cm long; bearing few spikelets. Primary panicle branches spreading; 1 -nate; sparsely divided; 15-35 cm long. Panicle axis glabrous. Panicle branches with prominent pulvini. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 9-10.4 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; laterally compressed; 9-10.4 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume ovate; 0.9-1.6 mm long; coriaceous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex obtuse; awned; 1 -awned. Upper glume ovate; 1.7-2.5 mm long; coriaceous; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex obtuse; awned; 1 -awned.
    Florets
    Basal sterile florets similar; barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 6.1-8.1 mm long; coriaceous; purple; 3-4 -veined; acuminate. Lemma of upper sterile floret ovate; 7.6-9.8 mm long. Fertile lemma ovate; 8-10 mm long; coriaceous; without keel; 3-5 -veined. Lemma surface glabrous. Lemma apex acuminate. Palea 1-1.4 mm long; coriaceous; 2-3 -veined; 1-keeled (at tip).
    Flowers
    Lodicules 3; 1.2-1.4 mm long; veined; glabrous; obtuse. Anthers 3; 3.5-5 mm long. Stigmas 2. Ovary glabrous.
    Fruits
    Caryopsis with adherent pericarp.
