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.

Senecio congestus of Michigan Flora.
A boreal circumpolar species, ranging south in the Great Lakes region sporadically to Minnesota, northern Wisconsin, and Michigan, where it has been collected only once: on the shore of Lake Michigan northwest of Harbor Springs, Emmet Co., in 1934.
This is a stout-stemmed species perhaps loosely resembling Erechtites hieraciifolius, but with at least the upper leaves ± clasping and the heads radiate (with light yellow rays).
