Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, 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.

Wolffiella gladiata B. S. Slaughter

Shallow, quiet waters near shores of lakes and ponds, often with other duckweeds and their relatives.

Like our species of Wolffia, this is a free-floating, rootless, aquatic, but with a totally different shape of plant body. This is a southern species, but known sparingly as far north as northern Ohio and Northern Indiana. It was first discovered in Michigan in Berrien Co., in 2017 by B. S. Slaughter.
