Perennial. Culms erect; 100-150 cm long. Culm-internodes solid. Leaf-sheaths keeled; glabrous on surface, or pubescent. Ligule a ciliolate membrane. Leaf-blades 30-60 cm long; 3-6 mm wide. Leaf-blade surface scabrous; rough adaxially; glabrous. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence compound; linear; 30-60 cm long; lax. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; enclosed. Spatheole linear, or lanceolate; 4-4.5 cm long; scarious; without tubercles; glabrous. Racemes 1; single; cuneate; bearing few fertile spikelets; bearing 1-2 fertile spikelets on each. Rhachis fragile at the nodes. Spikelets in pairs, or in threes. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster, or 2 in the cluster. Pedicels oblong; 1 mm long; tip oblique.
Morphology Reproductive morphology Inflorescences Spikelets
Basal sterile spikelets well-developed; 4 in number; forming an involucre about the fertile; with normal internodes; subsessile; 12-20 mm long; larger than fertile. Basal sterile spikelet glumes scarious; pilose; with red hairs; lower glume muticous. Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; 10-15 mm long; as long as fertile, or longer than fertile; separately deciduous. Companion sterile spikelet callus linear; 2-2.5 mm long; truncate. Companion sterile spikelet glumes tuberculate; villous; with red hairs. Companion sterile spikelet lemmas 2; enclosed by glumes. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; subterete; 10 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus cuneate; 2 mm long; pubescent; base pungent; attached obliquely. Spikelet callus hairs red.

Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; coriaceous; without keels. Lower glume surface pubescent. Lower glume hairs red. Upper glume oblong; coriaceous; 3 -veined. Upper glume surface pubescent. Upper glume hairs red.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; hyaline. Fertile lemma linear; hyaline; without keel; 1 -veined. Lemma apex entire; awned; 1 -awned. Principal lemma awn apical; geniculate; 35-70 mm long overall; with twisted column. Column of lemma awn hispidulous. Palea absent or minute.
