Descriptions

Morphology General Habit
Perennial; caespitose; clumped densely. Culms erect; 40-80 cm long. Leaves mostly basal. Leaf-sheaths outer margin glabrous, or hairy. Ligule a ciliolate membrane; obtuse. Leaf-blades 5-20 cm long; 0.7-1.2 mm wide. Leaf-blade surface pubescent; hairy adaxially. Leaf-blade margins ciliate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; oblong; interrupted; 6.5-7 cm long; 0.7-1.2 cm wide. Panicle axis puberulous. Panicle branches puberulous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising (2-)3 fertile florets; with diminished florets at the apex. Spikelets oblong, or cuneate; laterally compressed; 6.5-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising (2-)3 fertile florets; with diminished florets at the apex. Spikelets oblong, or cuneate; laterally compressed; 6.5-7 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; reaching apex of florets; similar to fertile lemma in texture; shiny. Lower glume oblong; 4-4.5 mm long; 0.66 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume oblong; 6-7 mm long; 1.25 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume primary vein scabrous. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate, or ovate; 4.8-5.5 mm long; membranous; shiny; keeled; 3 -veined. Lemma midvein scabrous. Lemma surface glabrous. Lemma apex acute; muticous. Palea gaping; elliptic; 4-5.5 mm long. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; oblong; 0.6-0.7 mm long; membranous; 2-toothed. Anthers 3; 2-2.3 mm long.
