--><p>Variety acutifolia forms natural hybrids with <i>Salix arctica</i> and <i>S. niphoclada</i>.</p><!--
--><p>Variety acutifolia × <i>Salix niphoclada</i>, known from Alaska and Yukon, is intermediate between the parents. It combines the petioles, the narrowly elliptic-oblanceolate leaves with acute-attenuate apices, the stipules, and the narrow, loosely flowered catkins of <i>S. niphoclada</i>, and the relatively long petioles, the larger oblanceolate leaves, the larger stipules, and the densely flowered and broadly cylindrical catkins of <i>S. glauca</i> (G. W. Argus 1965).</p>
