Discussion

Mat-saltbush is known to form intermediates with both Atriplex confertifolia and A. gardneri var. cuneata. This saltbush is a valuable browse plant on the sparsely vegetated clays and silts of eastern Utah, especially on the Mancos Shale exposures, where it is often the only woody vegetation present.
