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.

A. A. Reznicek
A Eurasian species, not as showy as M. scorpioides or M. sylvatica, but locally common along forested trails and roadsides, clearings, shores, lawns, old gardens; more often in weedy places than undisturbed forests. First collected in 1883 in Ingham Co.
Herbarium specimens of M. sylvatica with shriveled or immature corollas are easily misidentified as M. arvensis. One should look for corollas displaying a well-pressed limb to be sure of having this small-flowered species. White-flowered plants may be locally common with blue-flowered ones.
