Polygonum punctatum of Michigan Flora.

Marshes, edges of lakes and rivers, shores, and mucky hollows, often in very wet places (even cold spring-fed areas) and seems frequently to grow in somewhat more shaded places than other smartweeds.

The inflorescences tend to be straight, while in P. hydropiper they tend to nod.
