Echinochloa walteri A. A. Reznicek

Banks of rivers and ponds, ditches, marshes and wet shores, locally common in the marshes at the western end of Lake Erie.

The awn on the second glume is sometimes much shorter than the one on the sterile lemma; but often it is as long, and the spikes have a very dense, bristly look compared to the other species. The sheaths are very rarely smooth [f. laevigata Wiegand].
