Morphology General Habit
Perennial; caespitose. Butt sheaths glabrous. Culms erect; 100-165 cm long. Culm-internodes distally glabrous. Culm-nodes glabrous. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 5-6 mm long. Leaf-blades 40-75 cm long; 10-12 mm wide; aromatic. Leaf-blade surface scabrous; rough on both sides; glabrous.
Morphology Reproductive morphology Inflorescences
Synflorescence compound; linear; 30-90 cm long; dense, or lax. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; enclosed. Spatheole elliptic; 1.1-1.2 cm long. Peduncle 0.5-0.6 cm long; glabrous. Racemes 2; paired; deflexed; 1-1.2 cm long. Rhachis fragile at the nodes; semiterete; glabrous on surface; ciliate on margins. Rhachis internodes linear. Rhachis internode tip transverse; cupuliform. Raceme-bases flattened; unequal (the longer measured). Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels linear; semiterete; ciliate.
Morphology Reproductive morphology Inflorescences Spikelets
Basal sterile spikelets well-developed; 2 in number (lower raceme); 0 in upper raceme; with normal internodes; sessile and pedicelled. Basal sterile spikelet pedicels free; linear. Basal sterile spikelets male; equalling fertile. Basal sterile spikelet lower glume muticous. Companion sterile spikelets well-developed; male; lanceolate; 4 mm long; as long as fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; 7 -veined; acute; muticous. Companion sterile spikelet lemmas 2; enclosed by glumes. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 3.5-4.5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus base obtuse; inserted.

Lower glume lanceolate; 1 length of spikelet; chartaceous; 2-keeled; keeled all along; keeled laterally; winged on keel; winged narrowly. Lower glume intercarinal veins absent, or obscure; 0-2 in number. Lower glume surface concave; impressed below. Upper glume lanceolate; 1-keeled; keeled above. Upper glume apex acute.
