(Saline Atriplex)

The Flora of North America states "The species [Atriplex dioica] forms a mirror-image set of specimens with the remarkably similar Atriplex prostrata, from which it may be distinguished in most cases by the thickened, merely ovate to lanceolate leaf blades, and less commonly but in some localities exclusively triangular-hastate to lanceolate, mostly scurfy and prominently 3-veined leaf blades". I believe this specimen (Plant A) is part of the first (bolded) group.

However, two species are so close that the Flora of North America goes on to say  "There does not seem to be any consistent feature or combination of features by which all specimens can be assigned to one or the other of the two taxa. Whether there are intermediates between diploid (2n = 18) A. prostrata and tetraploid or hexaploid (2n = 36, 54) A. dioica is not known".
