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.

Included in L. minor in Michigan Flora.
Similar habitats to L. minor; floating on the surface of standing, even stagnant water of lakes, ponds, borders of streams, quiet backwaters, floodings, etc.
This species is said to be unique among our duckweeds in overwintering by producing, in the fall, small rootless dark green turions that sink. See notes under L. minor for further distinctions. Most of our collections have been determined by Landolt (see also Landolt, 1986).
