This herb grows in lakes and rivers, forms clumps, and can reach 1-2 m in height. The stem is midair and 1.5-2 cm in across. The leaves are broad linear and fine euralia-like textured. The panicles bear on the stem apices from August to October. The upper spikelets are female and the underneath spikelets are male.
