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.

M. R. Penskar
Sandy shores of lakes and ponds, and sandy swales, with fluctuating water levels. First collected in Michigan by J. A. Churchill in Muskegon Co. (see Churchill, 1976).
This is a tiny annual, like Eleocharis geniculata in having shiny black achenes, but even smaller. Though occurring in the same habitats in Michigan as our coastal plain disjuncts, this is a species (in North America) of the south and southwest.
