Morphology General Habit
Perennial; caespitose. Basal innovations extravaginal. Culms geniculately ascending, or decumbent; 90-120 cm long; 3-5 -noded. Culm-internodes distally glabrous. Culm-nodes glabrous. Leaf-sheaths longer than adjacent culm internode; glabrous on surface. Ligule an eciliate membrane; 0.5-1 mm long. Collar glabrous. Leaf-blades filiform, or linear; 15-30 cm long; 0.5-2.5 mm wide; aromatic. Leaf-blade surface glabrous.
Morphology Reproductive morphology Inflorescences
Synflorescence compound; scanty; 17-25 cm long. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; enclosed. Spatheole elliptic; 2-4 cm long; glabrous. Peduncle 0.8-1.1 cm long; pilose above. Racemes 2; paired; erect; 2-2.5 cm long; bearing 3-5 fertile spikelets on each. Rhachis fragile at the nodes; semiterete; villous on surface; villous on margins. Rhachis hairs 4-7 mm long. Rhachis internodes linear; 2-2.5 mm long. Rhachis internode tip transverse; cupuliform. Raceme-bases flattened; subequal. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels linear; semiterete; 2-2.5 mm long; villous; with 4-7 mm long hairs.
Sterile
Basal sterile spikelets absent. Companion sterile spikelets well-developed; comprising 2 subequal glumes without lemmas; linear; 2 mm long; shorter than fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; acute; muticous.
Morphology Reproductive morphology Inflorescences Spikelets

Spikelets elliptic; dorsally compressed; 4.5-5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pilose; base obtuse; inserted. Spikelet callus hairs 0.6-1.2 mm long. Basal sterile spikelets absent. Companion sterile spikelets well-developed; comprising 2 subequal glumes without lemmas; linear; 2 mm long; shorter than fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; acute; muticous.
Fertile
