    Habit
    Perennial; caespitose. Rhizomes short; pachymorph. Culms scandent; pendulous at the tip; 1000 cm long; 7-30 mm diam.; woody. Culm-internodes terete; thin-walled; 20-30 cm long; light green; distally pruinose and glabrous, or pubescent. Culm-nodes flanged. Lateral branches dendroid. Bud complement 1. Branch complement several; in a clump; with 1 branch dominant. Culm-sheaths 15.5 cm long; 4 times as long as wide; purple; glabrous; truncate at apex; auriculate; with obtuse auricles. Culm-sheath ligule 0.2 mm high. Culm-sheath blade lanceolate; demarcated but persistent; erect; 6-13 cm long; 9-15 mm wide; glabrous on surface. Leaves 10-19 per branch. Leaf-sheaths glabrous on surface. Leaf-sheath auricles erect (on one side only); 2-3 mm long. Ligule an eciliate membrane; 0.5-1 mm long. Leaf-blade base truncate; with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 7-30 cm long; 9-32 mm wide. Leaf-blade surface pubescent; hairy abaxially. Leaf-blade apex attenuate.
    Inflorescences
    Synflorescence bractiferous; linear, or clustered at the nodes; in untidy tufts (of 1-3 spikelets); 30-40 cm long; open; with glumaceous subtending bracts; without axillary buds at base of spikelet; prophyllate below lateral spikelets; 3-5 cm long overall. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 7-17 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes elongated below proximal fertile floret. Rhachilla elongation 4 mm long.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 7-17 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes elongated below proximal fertile floret. Rhachilla elongation 4 mm long.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 2 mm long; scarious; without keels. Lower glume apex acute. Upper glume ovate; 3 mm long; scarious; without keels. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; ovate; 7 mm long. Fertile lemma ovate; 7 mm long; coriaceous; without keel. Lemma apex obtuse. Palea 8.5 mm long; coriaceous. Rhachilla extension 8 mm long. Apical sterile florets 1 in number; barren; linear; 4 mm long.
    Flowers
    Lodicules 3; ovate; obtuse, or acute. Anthers 6. Stigmas 3. Ovary umbonate; glabrous.
    Fruits
    Caryopsis with adherent pericarp; oblong; 4-5 mm long.
