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.

Poa arida spikelet B. S. Walters spikelet

Medians and verges of highways heavily salted in winter, introduced from farther west. Patches of this plant are a conspicuous pale silvery green in spring and easily seen. First collected in 1978, in Wayne Co. (Reznicek, 1980) and doubtless more common than the few collections suggest, since one has to risk life and limb to collect it. Michigan plants appear to match the northern Great Plains entity sometimes segregated as P. glaucifolia Scribn. & T. A. Williams.
