Dichanthelium depauperatum A. A. Reznicek

Panicum depauperatum of Michigan Flora.

Dry usually sandy or rocky open ground (rarely in moist places); jack pine, aspen, and oak forests; pine-covered dunes.

This species, D. linearifolium, and D. perlongum are not always easy to separate. It is likely that there is a small incidence of hybridization. A few collections have ± beaked spikelets, as in D. depauperatum, but (although slightly immature) they are nearly as small as in D. linearifolium. Sheaths may be pilose to glabrous or nearly so. The spikelets may be glabrous or pubescent.
