HABIT Perennial. Butt sheaths persistent and investing base of culm; with fibrous dead sheaths. Culms erect; 100 cm long; 4 mm diam.; 3 -noded. Leaf-sheaths longer than adjacent culm internode; glabrous on surface. Ligule an eciliate membrane; 0.5 mm long; scarious; erose; truncate. Leaf-blades 15–30(–45) cm long; 3–4 mm wide; stiff. Leaf-blade surface scaberulous; rough abaxially; pilose; sparsely hairy; hairy adaxially.
INFLORESCENCE Inflorescence composed of racemes. Peduncle pilose above.
Racemes numerous; borne along a central axis; 4–7 cm long. Central inflorescence axis 5 cm long. Rhachis fragile at the nodes; subterete; villous on margins. Rhachis internodes linear; 2–3 mm long.
Spikelets in pairs. Fertile spikelets sessile and pedicelled; 2 in the cluster. Pedicels linear; angular; 2–3 mm long; villous.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus square; 0.3 mm long; bearded; base obtuse; attached obliquely. Spikelet callus hairs 1–2 mm long; 0.25–0.5 length of spikelet.
GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate, or oblong; 1 length of spikelet; chartaceous; 2-keeled. Lower glume intercarinal veins absent. Lower glume surface flat; villous; hairy below. Lower glume hairs 4 mm long. Lower glume apex acute. Upper glume lanceolate; chartaceous; with hyaline margins; 1-keeled. Upper glume primary vein eciliate, or ciliate. Upper glume surface pilose. Upper glume muticous.
FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate, or ovate; 3 mm long; hyaline; ciliolate on margins; fringed above. Fertile lemma elliptic; hyaline; without keel. Lemma apex entire; awned; 1 -awned. Principal lemma awn geniculate; 5–8 mm long overall; with twisted column. Column of lemma awn glabrous.
FLOWER Anthers 3; 2 mm long; yellow. Stigmas purple.
