Discussion

I have seen no specimens of this species and therefore it is not mapped. H. M. Hall and F. E. Clements (1923) in discussion of the related Atriplex lindleyi (as A. halimoides) noted that it has “been grown in American gardens with the thought of using them as forage plants, but…has [not] been found suitable for general planting. P. G. Wilson (1984) indicated that the species is relatively widespread in Australia, mainly in southern parts, where it grows “often on flood-plains or sandy flats.”
