Panicum commutatum of Michigan Flora.

Sandy open or somewhat forested ground, apparently not common; all recent records are from SW Michigan 

Our few collections are almost all the somewhat more northern subsp. ashei  (G. Pearson ex Ashe) Freckmann & Lelong, which differs most obviously in having narrower leaves mostly 715 mm wide and 615 times as long as wide. A single collection, by W. S. Martinus in 2016, from Berrien Co., is the typical subsp. commutatum with the widest leaf blades 13−23 mm wide, and only 4−6 times as long as wide.
