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.

1. Plant an erect herb with flat linear to narrowly elliptic leaves that expose the stem; style (if any) shorter than the ovary.

2. Petals 5, yellow, showy but readily falling (or absent in cleistogamous flowers); stigma on a distinct style; leaves with stellate hairs.


2. Petals 3, reddish, seldom expanded, mostly concealed by the sepals (cleistogamous flowers none); stigmas sessile or nearly so; leaves glabrate or with simple hairs.
