Morphology General Habit
Perennial; caespitose. Culms 20-40 cm long. Lateral branches lacking. Leaf-sheaths pilose. Ligule an eciliate membrane; 0.5-1 mm long; obtuse. Leaf-blades involute; 2-3 cm long; 1-3 mm wide. Leaf-blade surface pilose.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; dense; 3-5 cm long; bearing few spikelets. Primary panicle branches sparsely divided. Panicle axis pubescent. Panicle branches pubescent. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 4-8 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 13-15 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 4-8 fertile florets; with diminished florets at the apex. Spikelets ovate; laterally compressed; 13-15 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume lanceolate; 6 mm long; 0.9 length of upper glume; membranous; purple; without keels; 3 -veined. Lower glume surface pubescent. Lower glume apex acute. Upper glume lanceolate; 8 mm long; 0.75-1 length of adjacent fertile lemma; membranous; purple; without keels; 3 -veined. Upper glume surface pubescent. Upper glume apex acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma lanceolate; 8-10 mm long; chartaceous; without keel; 5-7 -veined. Lemma surface pubescent; hairy all along. Lemma apex awned; 1 -awned. Principal lemma awn subapical; 4 mm long overall. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Lodicules 2; membranous. Anthers 3. Ovary with a fleshy appendage above style insertion; pubescent on apex.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp; hairy at apex; apex fleshy. Hilum linear.
