Zusammenfassung:Atriplex minuticarpa, a new annual species from Eastern Utah is described and illustrated. The new species appears to be restricted to the Tununk-Shale Member of Mancos Shale in Emery, Grand and Wayne Counties of Utah. It is morphologically closest to A. powellii but differs in its divaricate-branching habit, densely imbricate, sessile leaves, small fruiting bracts and utricles, and monoecious inflorescenses with staminate and pistillate flowers in mixed glomerules.
