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.

Deciduous forest understories and edges; forming dense mats. First collected in Michigan in 2011 in Lenawee Co.
This is a dangerous pest, very recently discovered in Michigan, and hopefully, it will be possible to contain its spread. To the south, it has densely invaded forest understories, and seriously altered them. The decumbent bases of this annual, with its stilt-like roots will allow easy identification, especially contrasted with the perennial rhizomes of the somewhat similar forest understory species Leersia virginica. Spikelets can be either awned or awnless; both variants have been collected in Michigan.
