Summary
DescriptionAgropyron (Pascopyrum) smithii.jpg
English: Although seldom encountered in the natural vegetation of this region, western wheatgrass was locally common along roadsides, indicating its abundance in this region was due to roadside plantings rather than naturally occurring. For example, western wheatgrass was not found in the sagebrush steppe and other grassy vegetation in the Nine Mile Prairie area. The long glumes (as long or longer than adjacent lemma) with narrowly attenuating sharp tips, which give the entire spike a very rigid feel, are diagnostic of western wheatgrass and very different from the shorter less rigid glumes of thickspike wheatgrass.
