Descriptions

Morphology General Habit
Perennial; caespitose; clumped densely. Culms geniculately ascending; 30-60 cm long. Culm-internodes distally glabrous. Leaf-sheaths open for most of their length; smooth. Ligule an eciliate membrane; 1 mm long; scaberulous on abaxial surface; obtuse. Leaf-blades convolute; 4-8.5 cm long; 2-3 mm wide; glaucous. Leaf-blade surface ribbed; grooved adaxially; scabrous; rough adaxially. Leaf-blade margins scaberulous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; ovate; effuse; 8-17.5 cm long; 7-13 cm wide. Primary panicle branches reflexed; 1-4 -nate; 3-7 cm long. Panicle branches scabrous; rough distally. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 5-6 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 5-6 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; 0.7-1.4 mm long; 0.5-0.66 length of upper glume; membranous; purple; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume margins ciliolate. Lower glume apex acute. Upper glume elliptic; 1.5-2.2 mm long; 0.66 length of adjacent fertile lemma; membranous; purple; without keels; 5 -veined. Upper glume surface smooth, or asperulous; rough on veins. Upper glume margins ciliolate. Upper glume apex obtuse, or acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma elliptic; 2.5-3 mm long; membranous; much thinner above; without keel; 5 -veined. Lemma lateral veins obscure; stopping well short of apex. Lemma surface smooth, or scaberulous; rough above and on veins; puberulous; hairy below; hairy on veins. Lemma margins ciliolate; hairy above. Lemma apex obtuse. Palea 1 length of lemma; 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Anthers 3; 1.4-1.8 mm long. Ovary glabrous.

Caryopsis with adherent pericarp. Hilum punctiform.
