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.

with floating leaves
Streams, rivers, ditches, lakes, and streams; usually in shallow water or on wet shores.
Plants of this species often produce floating leaves on the surface of the water and, when submersed, long ribbon-like phyllodial leaves. These somewhat resemble leaves of Vallisneria or submersed forms of Sparganium, but differ in venation and in not being so definitely parallel-sided. The floating leaves are arrow-shaped (or some only lanceolate to narrowly ovate or elliptic); the other species in the genus apparently do not produce floating leaves.
