Morphology General Habit
Perennial; caespitose. Culms erect; 100-120 cm long. Ligule an eciliate membrane. Leaf-blades filiform, or linear; flat, or conduplicate; 15-30 cm long; 2-3 mm wide; aromatic.
Morphology Reproductive morphology Inflorescences
Synflorescence compound; linear; 20-30 cm long; lax. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; enclosed. Racemes 2; paired; deflexed; 2-3 cm long; bearing 5-8 fertile spikelets on each. Rhachis fragile at the nodes; semiterete; ciliate on margins. Rhachis internodes linear. 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; ciliate; hairy on margins.
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 equalling fertile. Companion sterile spikelets well-developed; male; lanceolate; 6 mm long; as long as fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; distinctly veined; acute; muticous. Companion sterile spikelet lemmas 2; enclosed by glumes. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; 6 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus base obtuse; inserted.
Sterile

Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; 6 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus base obtuse; inserted.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; chartaceous; 2-keeled; keeled all along; keeled laterally; winged on keel; winged narrowly; winged above. Lower glume intercarinal veins distinct. Lower glume surface concave. Upper glume lanceolate; 1-keeled. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret hyaline. Fertile lemma lanceolate; hyaline; without keel. Lemma apex lobed; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 10-12 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.
