|discussion=<p><i>Amelanchier intermedia</i> is morphologically closest to <i>A. laevis</i>. In a study of morphologic variation involving <i>A. canadensis</i>, <i>A. intermedia</i>, <i>A. laevis</i>, and other species of <i>Amelanchier</i>, A. C. Dibble et al. (1998) found that the only two species that overlap are <i>A. intermedia</i> and <i>A. laevis</i>. P. Landry (1975) considered <i>A. intermedia</i> to be the hybrid of <i>A. arborea</i> (including <i>A. laevis</i>) and <i>A. canadensis</i>, and the authors have data that suggest <i>A. intermedia</i> is a hybrid of <i>A. canadensis</i> and <i>A. laevis</i>.</p><!--
--><p><i>Amelanchier intermedia</i> hybridizes with <i>A. bartramiana</i>, <i>A. humilis</i>, and <i>A. spicata</i> (L. Cinq-Mars 1971).</p><!--
--><p>A. C. Dibble et al. (1998) reported that two individuals of <i>Amelanchier intermedia</i>, both tetraploids, were apomictic.</p>
