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.

Another halophytic grass with similar wiry stems and leaves, Distichlis spicata (L.) Greene, is known elsewhere in the Great Lakes region, and may be found in Michigan. It has inflorescences with short-pediceled spikelets in narrow panicles.
