Perennial; caespitose; clumped densely. Rhizomes short; pachymorph. Culms scandent; 800-1200 cm long; 10-45 mm diam.; woody; with root thorns from the nodes. Culm-internodes semiterete; thin-walled, or thick-walled; scaberulous. Lateral branches dendroid. Bud complement 1. Culm-sheaths 4.5-5 times as long as wide; glabrous. Culm-sheath ligule 1 mm high. Culm-sheath blade triangular; demarcated but persistent; erect; 6 cm long; 20 mm wide. Leaves 5-13 per branch. Leaf-sheaths glabrous on surface; outer margin hairy. Leaf-sheath oral hairs ciliate; 2-3 mm long. Ligule an eciliate membrane; 1-1.2 mm long. Collar with external ligule. Leaf-blade base truncate, or cordate; with a brief petiole-like connection to sheath; petiole 0.3-0.6 cm long; petiole glabrous. Leaf-blades lanceolate; 12-16 cm long; 22-32 mm wide. Leaf-blade venation without cross veins. Leaf-blade surface glabrous. Leaf-blade margins scabrous. Leaf-blade apex acuminate.
Morphology Reproductive morphology Inflorescences
Synflorescence bractiferous; globose; axis 0.2-0.7 cm long; dense; with glumaceous subtending bracts; with axillary buds at base of spikelet; prophyllate below lateral spikelets. Spikelets ascending, or spreading, or deflexed. Fertile spikelets sessile.
Morphology Reproductive morphology Inflorescences Spikelets
