- Morphology General Habit
- Perennial; caespitose; clumped loosely. Rhizomes short. Culms erect; 50-120 cm long. Culm-internodes smooth. Leaf-sheaths smooth, or scaberulous; glabrous on surface. Ligule an eciliate membrane; 4-8 mm long. Leaf-blades flat; 8-15 cm long; 6-14 mm wide. Leaf-blade surface smooth, or scaberulous; rough adaxially; glabrous.
- Morphology Reproductive morphology Inflorescences
- Inflorescence a panicle. Panicle open; lanceolate; 12-22 cm long; 2-6 cm wide. Panicle branches smooth. Spikelets solitary. Fertile spikelets pedicelled.
- Morphology Reproductive morphology Inflorescences Spikelets
- Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 4-6 mm long; breaking up at maturity; disarticulating below each fertile floret.
- Fertile
- Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 4-6 mm long; breaking up at maturity; disarticulating below each fertile floret.
- Morphology Reproductive morphology Inflorescences Bracts Glume
- Glumes persistent; similar; shorter than spikelet, or reaching apex of florets; thinner than fertile lemma; shiny. Lower glume lanceolate; 2-4 mm long; 0.5-0.7 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface smooth; glabrous. Lower glume apex obtuse, or acute. Upper glume lanceolate; 3-6 mm long; membranous; 1-keeled; 3 -veined. Upper glume primary vein smooth. Upper glume surface glabrous. Upper glume apex obtuse, or acute.
- Morphology Reproductive morphology Flowers Florets
- Basal sterile florets similar; male; with palea; attached to and deciduous with the fertile. Lemma of lower sterile floret lanceolate; 4-6 mm long; chartaceous; 1-keeled; 5 -veined; scabrous; ciliolate on margins; emarginate. Lemma of upper sterile floret lanceolate; 4-6 mm long; chartaceous; scabrous; ciliate on margins; emarginate; awned. Awn of upper sterile floret 2-4 mm long. Fertile lemma lanceolate; 3 mm long; cartilaginous; shiny; without keel. Lemma surface scaberulous; rough above. Lemma margins convolute; covering most of palea. Lemma apex obtuse. Palea 1 -veined; without keels.
