Descriptions
- Morphology General Habit
- Perennial; caespitose; clumped loosely. Rhizomes short. Culms 60-80 cm long; 1-2 -noded. Leaf-sheaths glabrous on surface. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 0.3-0.5 mm long. Leaf-blades 6-13 cm long; 2.5-4 mm wide. Leaf-blade venation comprising 15-17 vascular bundles; with sclerenchyma strands below veins and above all veins. Leaf-blade margins smooth.
- Morphology Reproductive morphology Inflorescences
- Inflorescence a panicle. Panicle open; ovate; loose; 8-20 cm long. Primary panicle branches 2 -nate; 3-9 cm long. Panicle branches flexuous. Spikelets solitary. Fertile spikelets pedicelled.
- Morphology Reproductive morphology Inflorescences Spikelets
- Spikelets comprising 3-8 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 10-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.8-2.2 mm long; smooth.
- Fertile
- Spikelets comprising 3-8 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 10-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.8-2.2 mm long; smooth.
- Morphology Reproductive morphology Inflorescences Bracts Glume
- Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 4-6 mm long; 0.66-0.85 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface smooth. Lower glume apex obtuse. Upper glume lanceolate; 6-7 mm long; 0.75 length of adjacent fertile lemma; chartaceous; without keels. Upper glume surface smooth. Upper glume apex obtuse.
- Morphology Reproductive morphology Flowers Florets
- Fertile lemma ovate; 7.5-9 mm long; chartaceous; without keel; 5 -veined. Lemma surface scaberulous, or punctate. Lemma apex emarginate, or obtuse; mucronate, or awned; 1 -awned. Principal lemma awn 4.5-13 mm long overall. Palea 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
