|discussion=<p>Plants of Anemone piperi from southeastern Washington and northeastern Oregon (i.e., the westernmost limits of the species) are sometimes intermediate between A. piperi and A. oregana. Although they possess vertical rhizomes characteristic of A. piperi, they have the bluish or pinkish sepals of A. oregana. These plants are best referred to A. piperi, pending detailed biosystematic analysis.</p>
