    Habit
    Perennial. Rhizomes short; pachymorph. Culms erect; 200-1000 cm long; 10-25 mm diam.; woody. Culm-internodes terete. Lateral branches dendroid. Branch complement three; with subequal branches. Culm-sheaths yellow, or green, or purple; pilose; hairy above; with appressed hairs; setose on shoulders; shoulders with 3 mm long hairs. Culm-sheath blade linear; as wide as sheath at base; 6-15 cm long; 2-5 mm wide; glabrous on surface, or pubescent. Leaves 4-7 per branch. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs scanty; deciduous; 0.5-3 mm long. Ligule an eciliate membrane; 0.3-0.6 mm long; truncate. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades deciduous at the ligule; lanceolate; 6-15 cm long; 5-11 mm wide. Leaf-blade surface glabrous; hairless throughout, or except near base.
    Inflorescences
    Inflorescence a panicle. Panicle open; 5-10 cm long. Spikelets solitary. Fertile spikelets pedicelled. Pedicels smooth.
    Spikelets
    Spikelets comprising 3-7 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 30-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes zig-zag; 4-6 mm long; eventually visible between lemmas.
    Fertile
    Spikelets comprising 3-7 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 30-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes zig-zag; 4-6 mm long; eventually visible between lemmas.
    Glume
    Glumes persistent; similar; shorter than spikelet; similar to fertile lemma in texture. Lower glume ovate; 3.5-6.5 mm long; herbaceous; without keels; 5 -veined. Lower glume apex setaceously attenuate. Upper glume ovate; 4-9 mm long; herbaceous; without keels; 2-7 -veined. Upper glume apex setaceously attenuate.
    Florets
    Fertile lemma ovate; 11-15 mm long; herbaceous; without keel; 9-11 -veined. Lemma surface scabrous. Lemma apex awned; 1 -awned. Principal lemma awn 3-6 mm long overall. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 3; membranous. Anthers 3; 5-6.5 mm long. Stigmas 3. Ovary glabrous.
    Fruits
    Caryopsis with adherent pericarp; 6-8.5 mm long.
