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

The lemmas appear distinctly pointed in this species, and exceed their paleas – often by as much as 0.5 mm or slightly more. In G. grandis and G. striata, the lemmas are about the same length as their paleas or exceed them slightly with broad scarious tips. Glyceria canadensis apparently does not produce the aquatic leaf form of G. borealis.
