Morphology General Habit
Perennial; caespitose. Culms erect; 60-70 cm long. Culm-internodes distally glabrous. Culm-nodes glabrous. Leaves mostly basal. Leaf-sheaths striately veined; smooth; glabrous on surface. Ligule a ciliolate membrane. Leaf-blades 10-15 cm long; 2-3 mm wide. Leaf-blade midrib prominent beneath. Leaf-blade venation distinct; with 8 secondary veins. Leaf-blade surface smooth; glabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence compound; scanty. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole. Spatheole linear, or lanceolate; 3-5 cm long. Peduncle 6-9 cm long; hirsute above. Racemes 2; paired; 1.5-2 cm long. Rhachis fragile at the nodes; villous on margins. Rhachis hairs 4-5 mm long. Rhachis internodes filiform; 3-4 mm long. Rhachis internode tip transverse; cupuliform; with lobed rim. Spikelets ascending; in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels filiform; 3.5-4.5 mm long; villous; with 4-5 mm long hairs.
Morphology Reproductive morphology Inflorescences Spikelets
Companion sterile spikelets represented by single glumes; linear; 2-3 mm long. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets linear, or lanceolate; dorsally compressed; 4-5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pilose; base obtuse; inserted.
Sterile
Companion sterile spikelets represented by single glumes; linear; 2-3 mm long.
Fertile
Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets linear, or lanceolate; dorsally compressed; 4-5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pilose; base obtuse; inserted.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume linear, or lanceolate; 1 length of spikelet; membranous; 2-keeled; keeled laterally. Lower glume intercarinal veins absent. Lower glume surface concave. Lower glume apex dentate; 2 -fid. Upper glume linear; membranous; 1-keeled. Upper glume apex acute; muticous.
Morphology Reproductive morphology Flowers Florets
Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 3.5-4.5 mm long; hyaline; 2 -veined; ciliolate on margins. Fertile lemma oblong; 1.5-1.8 mm long; hyaline; without keel. Lemma margins ciliolate. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 8-10 mm long overall; with twisted column. Column of lemma awn glabrous.
