Descriptions

Morphology General Habit
Perennial; caespitose; clumped loosely. Cataphylls inconspicuous. Culms 30-50 cm long; 1-2 mm diam. Leaf-sheaths open for most of their length. Ligule an eciliate membrane; 1-2 mm long. Leaf-blades flat, or convolute; 1.2-3 mm wide. Leaf-blade surface scaberulous.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle open; elliptic; 10-25 cm long. Primary panicle branches 7-13 cm long. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed slightly; 4-5 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed slightly; 4-5 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes persistent; shorter than spikelet. Lower glume ovate; 1 mm long; 0.75 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex obtuse. Upper glume ovate; 1.5 mm long; 1 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume apex obtuse.
Morphology Reproductive morphology Flowers Florets

Lemma apex obtuse. Palea 2 -veined. Palea keels scabrous; ciliolate. Apical sterile florets resembling fertile though underdeveloped.
