Discussion | Varieties 3 (3 in the flora). Although placed within the Atriplex argentea species complex by P. C. Standley (1916), this taxon appears more nearly allied to A. cordulata, differing mainly in leaf shape, round-ovate or deltoid-ovate to elliptic or lanceolate (not ovate to cordate-ovate), and markedly tuberculate faces of the fruiting bracteoles.
