Both species are effective sand binders and dune stabilizers. They are sometimes mistaken for Leymus arenarius and L. mollis, which grow in the same habitats and have a similar habit, but species of Leymus have more than 1 floret per spikelet.</p> |tables= |references={{Treatment/Reference |id=cope1994a |text=Cope, E.A. 1994.
