|discussion=<p>Presence of <i>Salix amygdaloides</i> in Massachusetts, New Hampshire, and Vermont has not been verified; its occurrence in those New England states was reported by H. A. Gleason and A. Cronquist (1991), and by M. L. Fernald (1950).</p><!--
--><p>Hybrids:</p><!--
--><p><i>Salix amygdaloides</i> forms natural hybrids with <i>S. gooddingii</i> and <i>S. nigra</i>. Hybrids with <i>S. caroliniana</i> (N. M. Glatfelter 1898) and <i>S. eriocephala</i> (M. L. Fernald 1950) have been reported; no convincing specimens have been seen. Controlled pollination between <i>S. amygdaloides</i> and <i>S. eriocephala</i>, <i>S. interior</i>, and <i>S. petiolaris</i> set no seed; controlled pollination with <i>S. lucida</i> produced a few seeds; some seedlings suffered necrosis in the cotyledon stage (A. Mosseler 1990).</p><!--
--><p><i>Salix amygdaloides</i> × <i>S. gooddingii</i> (S. ×wrightii Andersson): This hybrid occurs throughout the Rio Grande Valley, Texas, and New Mexico (C. K. Schneider 1919; C. R. Ball 1961), and at Happy and Rio Frio, Texas, and Virgil Run, Arizona. The leaves are somewhat glaucous abaxially, as in <i>S. amygdaloides</i>, but they are linear to narrowly elliptic and branchlets are sparsely pubescent as in <i>S. gooddingii</i>.</p><!--
--><p><i>Salix amygdaloides</i> × <i>S. nigra</i> (S. ×glatfelteri C. K. Schneider) resembles <i>S. amygdaloides</i> in leaves somewhat glaucous abaxially, but usually linear or narrowly elliptic, as in <i>S. nigra</i>. The stipules are not as prominent as in <i>S. nigra</i> but are foliaceous on late leaves; it should be expected wherever the ranges of the two species overlap. The hybrid is common in Missouri, where N. M. Glatfelter (1894) estimated that ca. 40% of the populations were hybrids, and in Illinois (R. H. Mohlenbrock 1980; G. Wilhelm, pers. comm.). Putative hybrids occur also in Ontario. Narrow leaves are typical of juvenile plants of <i>S. amygdaloides</i> but even at that stage they tend to be broadest at the midpoint or toward the base rather than in a midzone as in <i>S. nigra</i>.</p>
