Morphology General Habit
Perennial. Rhizomes elongated; scaly. Culms erect; 90-150 cm long; 2-4 mm diam.; 5-7 -noded. Leaves cauline. Ligule a ciliolate membrane; 2-3 mm long. Leaf-blades linear to lanceolate; (7-)15-35 cm long; 8-20 mm wide. Leaf-blade surface pilose; hairy on both sides. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle with branches tipped by a raceme. Panicle open; lanceolate; nodding; 12-20 cm long; 2-4 cm wide. Primary panicle branches whorled at most nodes; 2-6 cm long. Panicle branches glabrous in axils, or bearded in axils. Racemes 2-3.5 cm long; bearing few fertile spikelets; bearing 7-11 fertile spikelets on each. Rhachis fragile at the nodes; subterete. Rhachis internodes cuneate; 2-3 mm long. Spikelets in pairs. Fertile spikelets sessile and pedicelled; 2 in the cluster. Pedicels cuneate; tip cupuliform.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 4.5-5.5 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus bearded; base obtuse; inserted. Spikelet callus hairs white; 0.25 length of spikelet.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 4.5-5.5 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus bearded; base obtuse; inserted. Spikelet callus hairs white; 0.25 length of spikelet.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume ovate; 1 length of spikelet; chartaceous; pallid; without keels; 5-9 -veined. Lower glume lateral veins ribbed. Lower glume surface pilose. Lower glume apex acute, or acuminate. Upper glume ovate; chartaceous; pallid; without keels; 3-7 -veined. Upper glume lateral veins ribbed. Upper glume surface pilose. Upper glume margins ciliate. Upper glume apex acute, or acuminate; mucronate.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets male; with palea. Lemma of lower sterile floret ovate; 4.5-5.5 mm long; 1 length of spikelet; hyaline; pilose; hairy above; acute. Fertile lemma linear; 4 mm long; hyaline. Lemma apex lobed; 2 -fid; with linear lobes; incised 0.66 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 7-12 mm long overall; with twisted column. Palea lanceolate; 0.8 length of lemma; hyaline; 0 -veined; without keels. Palea apex dentate; 2 -fid.
