    Habit
    Perennial. Culms erect; robust; 120-200 cm long. Culm-internodes distally glabrous. Lateral branches lacking. Leaves mostly basal. Leaf-sheaths as wide as blade at the collar; pubescent; outer margin hairy. Ligule a fringe of hairs. Leaf-blades 80 cm long; 10 mm wide; firm. Leaf-blade midrib widened. Leaf-blade surface glabrous; hairless throughout, or except near base. Leaf-blade margins cartilaginous; scabrous. Leaf-blade apex attenuate.
    Inflorescences
    Inflorescence a panicle with branches tipped by a raceme. Panicle 20-25 cm long. Primary panicle branches 3-6 cm long. Rhachis fragile at the nodes; subterete; ciliate on margins. Rhachis internodes filiform; 0.5 length of fertile spikelet. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels filiform; 0.75 length of fertile spikelet; ciliate.
    Sterile
    Companion sterile spikelets well-developed; male; lanceolate; 4.5-5 mm long; as long as fertile. Companion sterile spikelet glumes 7 -veined. Companion sterile spikelet lemmas 1-awned.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4.5-5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus bearded; base truncate. Companion sterile spikelets well-developed; male; lanceolate; 4.5-5 mm long; as long as fertile. Companion sterile spikelet glumes 7 -veined. Companion sterile spikelet lemmas 1-awned.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4.5-5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus bearded; base truncate.
    Glume
    Glumes reaching apex of florets; firmer than fertile lemma; shiny. Lower glume lanceolate; 1 length of spikelet; chartaceous; yellow; 2-keeled; 1-5 -veined. Lower glume lateral veins absent, or distinct. Lower glume surface glabrous, or pubescent. Lower glume apex emarginate, or obtuse. Upper glume lanceolate; 1 length of spikelet; chartaceous; 1-keeled; keeled above. Upper glume margins scaberulous. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; 4.3-4.8 mm long; hyaline; ciliate on margins; acute. Fertile lemma oblong; 1.5 mm long; hyaline. Lemma margins ciliolate; hairy above. Lemma apex lobed; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 9-10 mm long overall; with twisted column.
