Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, michiganflora.net will point to this new site.

The new site offers several benefits over the existing website, including real coordinate mapping, giving a clearer view of the density of documentation as well as more precision about plant distributions and their link to landforms. We will also have the ability to update species pages more regularly, both in terms of new collections and as more existing Michigan specimens are georeferenced. In addition, we have a better photo display, and offer indented keys.

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 develop into an aquatic form, and 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.
