Descriptions

Morphology General Habit
Perennial; caespitose. Butt sheaths withering. Culms geniculately ascending; 15-30 cm long. Leaf-sheaths open for most of their length. Ligule an eciliate membrane. Leaf-blades convolute; 1-2 mm wide. Leaf-blade surface smooth; glabrous. Leaf-blade margins scabrous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; lanceolate; 4-6 cm long. Primary panicle branches appressed. Panicle branches smooth, or scaberulous. 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; compressed slightly; 5-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous.
Fertile
Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed slightly; 5-6 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus glabrous.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume lanceolate; 1.2-1.5 mm long; 0.66-0.75 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse, or acute. Upper glume lanceolate; 1.8-2 mm long; 0.66 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex obtuse, or acute.
Morphology Reproductive morphology Flowers Florets
Fertile lemma obovate; 3-3.2 mm long; membranous; much thinner above; without keel; 5 -veined. Lemma lateral veins obscure; stopping well short of apex. Lemma margins ciliate. Lemma apex acute. Palea 1 length of lemma; 2 -veined. Palea keels smooth. Apical sterile florets resembling fertile though underdeveloped.
Morphology Reproductive morphology Flowers
Anthers 3; 1.5-1.8 mm long. Ovary glabrous.
Morphology Reproductive morphology Fruits
Caryopsis with adherent pericarp. Hilum punctiform.
