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