Ligule an eciliate membrane; 0.5-1 mm long. Leaf-blades 10-20 cm long; 2-4 mm wide; aromatic. Leaf-blade surface scaberulous; glabrous.
Morphology Reproductive morphology Inflorescences
Synflorescence compound; linear, or paniculate; 10-20 cm long; dense. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; enclosed. Spatheole elliptic; 2-2.1 cm long; herbaceous; pilose (below). Peduncle 0.6 cm long. Racemes 2; paired; erect; 1-1.5 cm long. Rhachis fragile at the nodes; semiterete; villous on surface. Rhachis hairs 5-7 mm long. 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; villous; with 5-7 mm long hairs.
Sterile
Basal sterile spikelets absent. Companion sterile spikelets well-developed; comprising 2 subequal glumes without lemmas; lanceolate; 3 mm long; shorter than fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; acute; muticous.
Morphology Reproductive morphology Inflorescences Spikelets

Spikelets lanceolate; dorsally compressed; 4.5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus base obtuse; inserted. Basal sterile spikelets absent. Companion sterile spikelets well-developed; comprising 2 subequal glumes without lemmas; lanceolate; 3 mm long; shorter than fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; acute; muticous.
Fertile

Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate; 1 length of spikelet; chartaceous; 2-keeled; keeled all along; keeled laterally. Lower glume intercarinal veins distinct; 3 in number. Lower glume surface flat, or concave. Upper glume lanceolate; 1-keeled. Upper glume apex acute.
