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.

Sisyrinchium strictum inflorescence A. A. Reznicek inflorescence

Gravelly and sandy soil; edge of forests in rocky ground (Baraga Co.); very local and essentially endemic to the Great Lakes region.

This is like Sisyrinchium atlanticum in having narrow stems not darkening on drying and a tendency for the spathes to be geniculate at the base. However, it has the stems minutely denticulate on the margins, not smooth.
