|discussion=<p><i>Salix vestita</i> is an ancient amphiberingian species. Its distribution includes a series of isolated, disjunct populations in Central Siberia, the northern Rocky Mountains, the west coast of Hudson Bay, and the northeastern arctic and subarctic. Occurrence in Nunavut is on Akpatok Island in Ungava Bay and on the Belcher Islands in Hudson Bay. It may be extirpated in Washington.</p><!--
--><p>The flowering and vegetative branchlets sometimes have relatively short internodes. In subsequent years, branches have the appearance of short shoots similar to those in <i>Alnus</i>. Short shoots do not appear on all branches or in all years. The formation of short shoots may be related to adverse growing conditions.</p>
