Avenella flexuosa A. A. Reznicek

Deschampsia flexuosa of Michigan Flora.

Open generally dry sandy or rocky shores, dunes, and plains, usually associated with pine, oak, and aspen; particularly characteristic of jack pine plains and of the lumbered and burned-over sand ridges with Cladonia lichens and scattered pines along Lake Superior from Whitefish Bay west to the Pictured Rocks. Chiapella (2007) shows that Avenella is a distinct lineage from Deschampsia in the strict sense.
