Culm-internodes terete; solid; smooth; distally glabrous. Lateral branches lacking. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs ciliate. Ligule a ciliolate membrane; 0.5-1 mm long. Leaf-blades tapering towards tip and sheath; 35-90 cm long; 3-6 mm wide; coriaceous. Leaf-blade surface smooth, or scaberulous; glabrous; hairless except near base. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence a panicle with branches tipped by a raceme. Peduncle pilose above. Panicle open; ovate; dense; 12-15 cm long; 6-9 cm wide. Panicle axis with lower internodes 4-7 cm long. Racemes flexuous; 6-13 cm long. Rhachis fragile at the nodes; subterete; hirsute on surface. Rhachis hairs 5-6 mm long. Rhachis internodes linear; 2.5-3 mm long. Spikelets in pairs. Fertile spikelets sessile and pedicelled; 2 in the cluster; subequal. Pedicels linear; 2.5-3 mm long; villous.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3-4 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus bearded; base truncate. Spikelet callus hairs 3 mm long; 0.75 length of spikelet.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3-4 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus bearded; base truncate. Spikelet callus hairs 3 mm long; 0.75 length of spikelet.
    Glume
    Glumes similar; firmer than fertile lemma. Lower glume lanceolate; 1 length of spikelet; coriaceous; much thinner above; 2-keeled; 4 -veined. Lower glume surface flat; hirsute. Lower glume apex dentate; 2 -fid. Upper glume lanceolate; 1 length of spikelet; coriaceous; much thinner above; without keels; 3 -veined. Upper glume surface glabrous (sessile), or hirsute (pedicelled). Upper glume margins ciliate. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; 3-4 mm long; hyaline; pilose; hairy at apex; obtuse. Fertile lemma linear, or lanceolate; hyaline; 1 -veined. Lemma margins ciliate; hairy above. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 8-10 mm long overall; with twisted column. Palea lanceolate; 1 mm long; hyaline. Palea surface pilose; hairy on margins; hairy above.
