Morphology General Habit
Perennial; caespitose. Culms geniculately ascending; 90-175 cm long; 2-4 mm diam.; wiry. Culm-internodes distally glabrous. Culm-nodes swollen. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane; 5 mm long. Leaf-blade base broadly rounded. Leaf-blades 10-30 cm long; 4-9 mm wide; coriaceous; aromatic. Leaf-blade surface glabrous.
Morphology Reproductive morphology Inflorescences
Synflorescence compound; linear; 12-20 cm long; dense, or lax. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; enclosed. Spatheole elliptic; 1.5-1.9 cm long. Racemes 2; paired; deflexed; 1.8 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.
Sterile
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, or ovate; 3 mm long; as long as fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; 5(-7) -veined; glabrous; acute; muticous. Companion sterile spikelet lemmas 2; enclosed by glumes.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 3-3.2 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus base obtuse; inserted. 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, or ovate; 3 mm long; as long as fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; 5(-7) -veined; glabrous; acute; muticous. Companion sterile spikelet lemmas 2; enclosed by glumes.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 3-3.2 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. Lower glume intercarinal veins absent, or distinct; 0-2 in number. Lower glume surface with V-shaped depression. 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; 2-7 mm long overall; with a straight or slightly twisted column. Column of lemma awn glabrous. Palea absent or minute.
