Discussion
A series of at least partially stabilized introgressants between Atriplex gardneri var. cuneata and var. utahensis in Carbon County form the basis of A. cuneata subsp. introgressa C. A. Hanson (type from Wellington, Hanson 346, 1961, holotype BRY!). The hybrids between var. cuneata and A. confertifolia have been described as A. neomexicana Standley; they occur where the ranges of the taxa overlap. The Castle Valley saltbush also forms apparent hybrids with A. canescens.
