|discussion=<p>Variety longistylis differs from <i></i>var.<i> alaxensis</i> mainly in its glaucous and less densely hairy branchlets. Some specimens of <i></i>var.<i> alaxensis</i>, in which the indumentum has been partially removed by wind erosion, show that they, too, have glaucous branchlets. The only fundamental difference between the two may be density of branchlet indumentum. Other differences, which appear in varietal descriptions, may represent inadequate sampling. These taxa sometimes intergrade and <i></i>var.<i> longistylis</i> may not be worthy of taxonomic recognition. It is included here only because of very conspicuous differences between the extremes.</p><!--
--><p>Hybrids:</p><!--
--><p>Variety longistylis forms natural hybrids with <i>Salix sitchensis</i>.</p><!--
--><p>Variety longistylis × <i>Salix sitchensis</i> grows with both parents at the mouth of the Twentyfour Mile River, south-central Alaska. The plants resemble <i></i>var.<i> longistylis</i> in having relatively long styles and stigmas, oblong nectaries, and sparsely hairy branchlets, and <i>S. sitchensis</i> in having brittle branches, weakly glaucous branchlets, hairs sparse and crinkled, and ovaries with straight hairs. Fruits were set but no seed developed.</p>
