Descriptions

Morphology General Habit
Perennial; culms solitary, or caespitose; clumped loosely. Basal innovations intravaginal. Culms erect; 15-35 cm long. Culm-internodes glaucous. Leaf-sheaths open for most of their length. Ligule an eciliate membrane; 2-3.5 mm long. Leaf-blades involute; 3-9 cm long; 0.5-2 mm wide; glaucous. Leaf-blade surface scaberulous; rough adaxially. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle contracted; elliptic; 5-10 cm long; 2 cm wide. Primary panicle branches 3-6 -nate; 2-3.5 cm long. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 5-6 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. Floret callus pubescent.
Fertile
Spikelets comprising 5-6 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. Floret callus pubescent.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; dissimilar; shorter than spikelet. Lower glume lanceolate, or ovate; 1.3-1.6 mm long; 0.6-0.8 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume lanceolate, or ovate; 1.6-2.5 mm long; 0.75-1 length of adjacent fertile lemma; membranous; without keels; 1-3 -veined. Upper glume lateral veins absent, or obscure. Upper glume margins ciliolate. Upper glume apex erose; obtuse.
Morphology Reproductive morphology Flowers Florets
Fertile lemma oblong, or ovate; 2-2.5 mm long; membranous; much thinner above; purple and yellow; bordered with last colour and tipped with last colour; without keel; 5 -veined. Lemma lateral veins obscure; stopping well short of apex. Lemma surface pubescent; hairy below. Lemma apex obtuse; muticous, or mucronate. Palea 1 length of lemma; 2 -veined. Palea keels scabrous; adorned above; with 0.33 of their length adorned. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Anthers 3; 1.3-1.5 mm long. Ovary glabrous.
