Descriptions

Morphology General Habit
Perennial; caespitose. Culms erect; 20-25 cm long. Ligule an eciliate membrane. Leaf-blades 3-9 cm long; 1 mm wide. Leaf-blade apex acute.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear; interrupted; 3-3.5 cm long. Panicle axis pubescent. Panicle branches pubescent. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 2 fertile florets; with a barren rhachilla extension, or with diminished florets at the apex. Spikelets obovate; laterally compressed; 3.5-4.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
Fertile
Spikelets comprising 2 fertile florets; with a barren rhachilla extension, or with diminished florets at the apex. Spikelets obovate; laterally compressed; 3.5-4.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; similar; shorter than spikelet; similar to fertile lemma in texture; shiny; gaping. Lower glume lanceolate; 2.5-3.5 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume lanceolate; 2.5-3.5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate; 2.5-3.5 mm long; membranous; much thinner on margins; shiny; keeled. Lemma apex dentate; 2 -fid; obtuse; muticous. Palea gaping. Apical sterile florets resembling fertile though underdeveloped.
