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.

Like the other members of the genus, inhabits roadsides and railroads, fields, fencerows, clearings, disturbed places, and shores. Our earliest collections are from Kent and Van Buren Cos. in 1880, but other counties in the 1880’s include Mecosta, Ingham, and Ionia, so the species must have been well established by then.

The achenes are smallest in this species, running at maturity ca. 1.8–2.5 cm long (excluding pappus).
