Culm-internodes terete; thin-walled; 10-70 cm long; mid-green; distally glabrous. Culm-nodes swollen. Lateral branches dendroid. Bud complement 1. Branch complement several; in a clump; thinner than stem. Culm-sheaths deciduous; hispid; with dark brown hairs; auriculate; setose on shoulders. Culm-sheath blade triangular. Leaves 5-13 per branch. Leaf-sheaths 4-8 cm long; glabrous on surface. Leaf-sheath oral hairs setose. Leaf-sheath auricles falcate. Ligule an eciliate membrane; truncate, or obtuse. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.2 cm long. Leaf-blades deciduous at the ligule; linear, or lanceolate; 8-20 cm long; 15-25 mm wide. Leaf-blade venation with 10-16 secondary veins. Leaf-blade surface pubescent; densely hairy; hairy abaxially. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence bractiferous; clustered at the nodes; in untidy tufts; with spathaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets; leafless between clusters.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 30-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.
Fertile
Spikelets comprising 4-5 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 30-40 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.
