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.

Corynephorus canescens Inflorescence B. S. Walters Inflorescence

Dry, sandy, sunny, disturbed habitats along trails and roadsides.

This densely tufted grass is a relatively recent introduction from Europe, first collected by A. A. Reznicek in Berrien Co. in 1982 (Gereau & Rabeler, 1984). It is now very locally frequent in the "sand country" of southwesterm Michigan and is probably increasing.

It somewhat resembles Koeleria, but has the filiform-involute leaf blades finely and densely scabrous, and differs in its unique, jointed awn. Koeleria has the blades smooth or sometimes sparsely pilose and the lemma awnless.
