|discussion=<p>Hybrids:</p><!--
--><p>Variety exigua forms natural hybrids with <i></i>var.<i> hindsiana</i>, <i>Salix columbiana</i>, <i>S. interior</i>, and <i>S. melanopsis</i>.</p><!--
--><p>Variety exigua × <i></i>var.<i> hindsiana</i> was reported by R. D. Dorn (1998). Inasmuch as the two varieties are subtly distinct, hybrids are difficult to recognize.</p><!--
--><p>Variety exigua × <i>Salix interior</i> probably occurs throughout their area of overlap; it is known to me from Alberta and Nebraska, where there are plants with leaves indistinctly toothed and more silky than in <i>S. interior</i>. R. D. Dorn (1998) reported it from Alberta, British Columbia, Colorado, Montana, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming.</p><!--
--><p>Variety exigua × <i>Salix melanopsis</i> is intermediate, with juvenile leaves densely hairy proximally, truncate floral bracts, and prominent stipules (R. D. Dorn 1998).</p>
