Morphology General Habit
Perennial. Culms erect; straight, or zigzag; 60-100 cm long; wiry. Culm-internodes elliptical in section. Lateral branches ample. Leaf-sheaths keeled. Ligule an eciliate membrane; 1-1.5 mm long; erose. Leaf-blades 10-20 cm long; 4-8 mm wide. Leaf-blade surface scabrous; rough abaxially; pilose; hairy adaxially; with tubercle-based hairs. Leaf-blade margins scabrous; ciliate; hairy at base. Leaf-blade apex acuminate; filiform.
Morphology Reproductive morphology Inflorescences
Synflorescence compound; paniculate; lax. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; enclosed. Spatheole lanceolate; 2.5-3 cm long; scarious; without tubercles; glabrous. Racemes 1; single; cuneate; bearing few fertile spikelets; bearing 2 fertile spikelets on each. Rhachis fragile at the nodes. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels oblong; 0.5 mm long; tip oblique.
Sterile
Basal sterile spikelets well-developed; 4 in number; forming an involucre about the fertile; with normal internodes; subsessile; lanceolate; 11-12 mm long; larger than fertile. Basal sterile spikelet glumes tuberculate; pilose; lower glume muticous. Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; 11-12 mm long; longer than fertile; separately deciduous. Companion sterile spikelet callus linear; 1.5 mm long; truncate. Companion sterile spikelet glumes glabrous. Companion sterile spikelet lemmas 2; enclosed by glumes.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; subterete; 5.5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus oblong; 1 mm long; pilose; base acute; attached obliquely. Basal sterile spikelets well-developed; 4 in number; forming an involucre about the fertile; with normal internodes; subsessile; lanceolate; 11-12 mm long; larger than fertile.

Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma; shiny. Lower glume oblong; 1 length of spikelet; chartaceous; without keels; 11 -veined. Lower glume surface scabrous; rough above; glabrous. Lower glume apex truncate. Upper glume oblong; chartaceous; 3 -veined. Upper glume apex truncate.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 4.5 mm long; hyaline; 0 -veined; without midvein; without lateral veins; ciliolate on margins. Fertile lemma linear; hyaline; without keel; 1 -veined. Lemma apex entire; awned; 1 -awned. Principal lemma awn apical; geniculate; 20-25 mm long overall; with twisted column. Column of lemma awn hispidulous. Palea absent or minute.
