Morphology General Habit
Perennial; caespitose. Butt sheaths glabrous; persistent and investing base of culm; with compacted dead sheaths, or curly dead sheaths. Culms erect, or geniculately ascending; 30-150 cm long. Ligule an eciliate membrane; 0.5-4 mm long. Leaf-blades 15-30 cm long; 3-5 mm wide; aromatic. Leaf-blade apex attenuate; filiform.
Morphology Reproductive morphology Inflorescences
Synflorescence compound; linear; 15-40 cm long; dense. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; enclosed. Spatheole lanceolate, or elliptic; 1.5-2.5 cm long; red. Racemes 2; paired; deflexed; 1.3-2.2 cm long. Rhachis fragile at the nodes; semiterete; pilose on surface; 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 surface and margins.
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; 6 mm long; as long as fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; distinctly veined; 3-7 -veined; 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 lanceolate; dorsally compressed; 4.5-5.5 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; 6 mm long; as long as fertile; deciduous with the fertile. Companion sterile spikelet glumes chartaceous; distinctly veined; 3-7 -veined; acute; muticous. Companion sterile spikelet lemmas 2; enclosed by glumes.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4.5-5.5 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 lanceolate; 1 length of spikelet; chartaceous; 2-keeled; keeled all along; keeled laterally. Lower glume intercarinal veins absent, or obscure; 0-2 in number. 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; incised 0.5 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 7-10 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.
