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.

B. S. Walters
Fens, openings in tamarack and cedar (also sometimes spruce) swamps, peaty streamside thickets, interdunal swales, sedge marshes and mat, sometimes in wet, open deciduous forests, rocky openings and outcrops; generally a calciphile and a good indicator of fens.
The leaf blades are of similar proportions to those of R. cathartica, but are more acute, may average a little larger, and have more pairs of lateral veins. These are strongly ascending and curve along the margins, much as in leaves of Cornus (which, however, are strictly entire).
