Bogs, marshy ground, moist sandy to mucky shores and interdunal hollows.
The broadly elliptic-rounded, nearly clasping leaves of this species may suggest a small version of Triadenum. Submersed stems may exhibit long internodes and small 3-nerved (but not punctate) rounded leaves [f. callitrichoides Fassett]; identification can usually be confirmed by association with fertile plants on an adjacent shore.
