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.

Wet areas: swamps, stream margins, swamps, seepy shores and banks, cedar swamps, rocky to sandy shores, often in somewhat disturbed areas, such as ditches or trails in moist forests, rarely in dry ground.
Although the stems are often described as pubescent, at least on plants not growing in water, the great majority of our specimens have glabrous stems. Small plants in drier places are not always easily distinguished from C. parviflora. A very few specimens of C. pensylvanica have been seen with sparsely ciliate petioles on the cauline leaves, but the plants are so tall and the leaf segments so broad that they can be readily separated from C. flexuosa or C. hirsuta.
