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.

R. W. Smith
A Eurasian species of local occurrence. A lawn weed in Ingham and St. Clair Cos. in the 1880’s, but except for a 1935 collection from Ann Arbor (Washtenaw Co.), not gathered again in the state until 1978; since, apparently spreading (or being discovered) rapidly along roadsides and in lawns, fields, plantations, vacant lots, logged areas, gravel pits, and other disturbed sites.
Good magnification (20–30×) and illumination at the right angle are often necessary to see, on the inside of the phyllaries, the distinctive tiny hairs that will identify this species and C. biennis if achenes are not mature.
