|discussion=<p>Plants with branchlets densely villous with white, gray, or, sometimes, ferruginous hairs have been named var. yukonensis. This hairy variant occurs scattered throughout populations in both North America and Russia and does not seem to warrant taxonomic recognition. The closely related Salix planifolia shows similar variation.</p><!--
--><p>Hybrids:</p><!--
--><p>Salix pulchra forms natural hybrids with S. planifolia and S. scouleriana.</p><!--
--><p>Salix pulchra × S. scouleriana is known from Alaska. It resembles S. pulchra in its long, linear stipules, general leaf shape, and relatively long styles; and S. scouleriana in its juvenile leaves with abundant ferruginous hairs, petioles densely villous to velvety, and relatively short stigmas.</p>
