Descriptions

Morphology General Habit
Perennial; caespitose. Rhizomes short; pachymorph. Culms erect; 800-1300 cm long; 30-60 mm diam.; woody; with root thorns from the nodes. Culm-internodes terete; thick-walled; mid-green and purple; mottled; distally glabrous. Lateral branches dendroid. Branch complement several. Culm-sheaths deciduous; glabrous; convex at apex; auriculate; with unequal auricles; ciliate on shoulders. Culm-sheath ligule 2-3 mm high; dentate. Culm-sheath blade triangular; erect. Leaves cauline. Ligule an eciliate membrane. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades lanceolate; 5-15 cm long; 8-12 mm wide. Leaf-blade surface pubescent; sparsely hairy; hairy abaxially. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence bractiferous; clustered at the nodes; in untidy tufts; with glumaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 25-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.
Fertile
Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 25-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.
