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.

floating leaves
In similar waters as the other species of Lemna, but in tangled masses beneath the water, not floating on the surface, and hence not easily seen. Very variable in size, the largest and most luxuriant plants found in cold spring-fed streams.
The margins of the plant bodies are ± dentate or erose, and fragmentary specimens or the very rare floating plants with shorter segments are thus distinguishable from L. minor or L. turionifera.
