|discussion=<p><i>Atriplex watsonii</i> is a sprawling plant that exhibits much variation in leaf size, as attested in the clearly staminate type collection, Palmer 334, wherein the range in size is from 5–25 × 2.5–11 mm wide. Although typically placed adjacent to <i>A. matamorensis</i>, the other dioecious perennial, the two taxa are probably not closely allied. The broader-leaved phases simulate closely <i>A. leucophylla</i>, with which it is sometimes confused, and perhaps the relationship lies in that direction, but it closely simulates <i>A. californica</i>, with which it is probably most closely allied.</p>
