Morphology General Habit
Perennial; caespitose; clumped loosely. Rhizomes elongated. Butt sheaths light brown; pubescent; persistent and investing base of culm. Culms 20-70 cm long. Ligule an eciliate membrane; 1-1.5 mm long; obtuse. Leaf-blades flat, or conduplicate; 10-15 cm long; 3-5 mm wide. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Inflorescence a panicle. Panicle spiciform; linear, or oblong; 1-3 cm long; 0.6-1 cm wide. Panicle axis with rounded ribs. Spikelets solitary. Fertile spikelets pedicelled. Pedicels oblong.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 5-5.5 mm long; falling entire.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; laterally compressed; 5-5.5 mm long; falling entire.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes connate along margins below; 0.9 of their length connate; similar; exceeding apex of florets; recurved at apex. Lower glume oblong; 5-5.5 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein ciliate. Lower glume lateral veins absent. Lower glume margins eciliate, or ciliate. Lower glume apex acuminate. Upper glume oblong; 5-5.5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein ciliate. Upper glume lateral veins absent. Upper glume margins eciliate, or ciliate. Upper glume apex acuminate.
Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 4.5-5 mm long; membranous; keeled; 3 -veined. Lemma apex attenuate; awned; 1 -awned. Principal lemma awn dorsal; arising 0.5 way up back of lemma; curved; 2.5 mm long overall; not or scarcely exserted from spikelet. Palea 2-2.5 mm long; 0.5 length of lemma; 1 -veined.
Morphology Reproductive morphology Flowers
Lodicules absent. Anthers 3. Stigmas protogynous; terminally exserted; pubescent. Ovary glabrous.
