Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, 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.


Leaves all cauline, more than 10 and usually entire; sepals without a basal auricle; lower petal notched or 2-lobed at apex and slightly saccate (but not spurred) at base.


Leaves all basal or fewer than 8 if cauline, toothed to crenulate; sepals with an appendage or auricle extending beyond their attachment at base of flower; lower petal not at all notched, but with a definite spur projecting backward at the base.
