Morphology General Habit
Perennial; caespitose. Rhizomes short; pachymorph. Culms leaning; pendulous at the tip; 2000-3000 cm long; 90 mm diam.; woody; with aerial roots from the nodes. Culm-internodes terete; dark green. Lateral branches dendroid. Culm-sheaths deciduous; 15-25 cm long; olive green; pubescent; auriculate; with 3-4 mm high auricles; setose on shoulders; shoulders with 15-20 mm long hairs. Culm-sheath ligule 5-10 mm high; dentate. Culm-sheath blade ovate; narrower than sheath; erect, or spreading; 25 cm long; 80 mm wide; glabrous on surface; acuminate. Leaf-sheath oral hairs lacking, or setose; 5-10 mm long. Ligule an eciliate membrane. Leaf-blade base truncate, or broadly rounded; with a brief petiole-like connection to sheath; petiole 0.2-0.6 cm long. Leaf-blades lanceolate; 15-30 cm long; 20-30 mm wide. Leaf-blade surface glabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence bractiferous; clustered at the nodes; in globose clusters; dense; with glumaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 10 mm long; breaking up at maturity; disarticulating below each fertile floret.
Fertile
Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 10 mm long; breaking up at maturity; disarticulating below each fertile floret.
Morphology Reproductive morphology Inflorescences Bracts Glume

Morphology Reproductive morphology Flowers Florets
Fertile lemma ovate; 8-9 mm long; chartaceous; without keel; 12 -veined. Lemma apex acuminate. Palea chartaceous; 4 -veined; without keels.
Morphology Reproductive morphology Flowers
