Culm-internodes terete; thin-walled; 40-60 cm long; distally glabrous, or hispid (black hairs). Lateral branches dendroid. Bud complement 1. Branch complement several to many; apparently arising below the node; with 1 branch dominant.

Culm-sheath ligule 1 mm high; entire. Culm-sheath blade ovate, or triangular; erect, or reflexed; 7-18 cm long; 25-60 mm wide; hispid; acuminate, or attenuate. Leaf-sheath oral hairs setose; curly. Leaf-sheath auricles falcate; 3 mm long. Ligule an eciliate membrane; 1 mm long; membranous. Leaf-blade base symmetrical; with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 9-26 cm long; 15-40 mm wide. Leaf-blade surface glabrous; hairless except near base. Leaf-blade apex attenuate; filiform.
    Inflorescences

    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 20-22 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 20-22 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes several; 2-4 empty glumes; similar; shorter than spikelet. Lower glume ovate; 3 mm long; 7 -veined. Lower glume apex setaceously attenuate. Upper glume elliptic; 7-11 mm long; 11-13 -veined. Upper glume surface glabrous, or pubescent. Upper glume hairs black. Upper glume apex setaceously attenuate.
    Florets
    Basal sterile florets barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret similar to fertile lemma. Fertile lemma lanceolate; 12-13 mm long; 13-15 -veined. Lemma surface glabrous, or pilose; hairy above. Lemma hairs black. Lemma apex attenuate. Palea tightly convolute around flower; 17-20 mm long; 14-16 -veined. Palea surface pilose; hairy above. Palea apex dentate. Rhachilla extension 1 mm long; pubescent.
