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