HABIT Perennial. Culms erect; 80–100 cm long; 4–8 mm diam. Culm-internodes alternately elongated and bunched; solid; 5–7 cm long (when long); distally pilose. Lateral branches lacking. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs bearded. Ligule a ciliate membrane. Leaf-blades linear, or lanceolate; 40–70 cm long; 10 mm wide; stiff; glaucous. Leaf-blade venation distinct. Leaf-blade surface glabrous; hairless except near base. Leaf-blade apex attenuate; filiform.

INFLORESCENCE Inflorescence a panicle.

Panicle open; linear, or oblong; dense; 10–20 cm long; 2–3 cm wide. Primary panicle branches 1 -nate; profusely divided. Panicle axis pubescent. Panicle branches pilose.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; obtuse; 4 mm long; falling entire.

GLUMES Glumes reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 0.5 length of spikelet; membranous; without keels; 3 -veined. Lower glume apex acute. Upper glume lanceolate, or oblong; 1 length of spikelet; membranous; without keels; 5 -veined. Upper glume lateral veins obscure. Upper glume apex obtuse, or acute.

FLORETS Basal sterile florets male; with palea. Lemma of lower sterile floret similar to upper glume; lanceolate, or ovate; 1 length of spikelet; membranous; 5 -veined; obscurely veined; obtuse, or acute. Fertile lemma elliptic; dorsally compressed; 3.5 mm long; indurate; pallid; shiny; without keel. Lemma margins involute. Lemma apex acute. Palea involute; indurate.

FRUIT Caryopsis with adherent pericarp.
