Leaf-sheath auricles erect. Ligule an eciliate membrane; 3-4 mm long. Leaf-blades 50-100 cm long; 2-5 mm wide. Leaf-blade margins scabrous. Leaf-blade apex attenuate; filiform.
    Inflorescences
    Inflorescence a panicle with branches tipped by a raceme. Peduncle glabrous. Panicle open; linear, or lanceolate; 18-25 cm long. Primary panicle branches sparsely divided. Racemes 2-6 cm long. Rhachis fragile at the nodes; subterete; villous on margins. Rhachis internodes filiform; 6-7 mm long. Spikelets in pairs. Fertile spikelets sessile and pedicelled; 2 in the cluster; subequal. Pedicels filiform; 3 mm long; villous.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or oblong; dorsally compressed; 6 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus pilose; base truncate. Spikelet callus hairs white; 1-1.5 mm long; 0.15-0.33 length of spikelet.

Spikelet callus hairs white; 1-1.5 mm long; 0.15-0.33 length of spikelet.
    Glume
    Glumes reaching apex of florets; firmer than fertile lemma. Lower glume elliptic, or oblong; 1 length of spikelet; cartilaginous; 2-keeled. Lower glume surface flat; villous. Lower glume hairs dark brown (3-4mm long). Lower glume apex emarginate. Upper glume elliptic; 1 length of spikelet; membranous; 1-keeled; keeled above; 3 -veined. Upper glume surface pilose; hairy above. Upper glume apex acute; awned; 1 -awned. Upper glume awn 0.5-3 mm long.
