Herbarium specimens of Persicaria hydropiperoides sometimes are misidentified as P. maculosa, especially when the roots are missing. The former species may be distinguished reliably by its achenes all trigonous (trigonous and biconvex achenes are mixed in the inflorescences of P. maculosa) and bristles on the margins of the ocreae that average longer. M. L. Fernald (1922c) reported hybrids with P. robustior from Nova Scotia.

Persicaria hydropiperoides is a New World species of flowering plant in the buckwheat family known by the common names swamp smartweed and false waterpepper. It is widespread across much of North America and South America.[3][4][5][6][7] It grows in moist and wet habitats, and is sometimes semi-aquatic.
Persicaria hydropiperoides is quite variable and is sometimes divided into several varieties, some of which may be better treated as species in their own right.[2]
In general, Persicaria hydropiperoides is a rhizomatous perennial herb growing upright or erect and approaching a maximum height of one meter (40 inches). Roots may emerge from nodes on the lower stem. The bristly lance-shaped leaves are around 10 centimeters (4 inches) long. The leaves have sheathing stipules known as ochrea. The spikelike inflorescence produces many pinkish flowers each about 3 millimeters wide.[2]
