    Habit
    Perennial; caespitose. Rhizomes short; pachymorph. Culms scandent; slender; woody. Culm-internodes terete; thick-walled; smooth; distally glabrous. Lateral branches fastigiate. Bud complement 1. Branch complement many; in a clump; subtended by a bare patch above the node; with subequal branches. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades deciduous at the ligule; lanceolate; 10-15 cm long; 8-10 mm wide; stiff. Leaf-blade surface glabrous.
    Inflorescences
    Inflorescence composed of racemes; terminal and axillary. Racemes 1; single; straight; bilateral; 7-20 cm long. Spikelet packing distant. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 2 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 10-15 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 1 basal sterile florets; 2 fertile florets; with diminished florets at the apex. Spikelets linear; laterally compressed; 10-15 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 1.5-3 mm long; chartaceous; without keels. Lower glume apex acuminate. Upper glume lanceolate; 3-4 mm long; chartaceous; without keels. Upper glume apex acuminate.
    Florets
    Basal sterile florets barren; without significant palea; persisting on inflorescence. Lemma of lower sterile floret similar to fertile lemma; lanceolate; 6 mm long; chartaceous; acuminate. Fertile lemma lanceolate; 7 mm long; chartaceous; without keel; 7 -veined. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 1 mm long overall. Palea 1 length of lemma. Apical sterile florets resembling fertile though underdeveloped.
