|discussion=<p><i>Amelanchier humilis</i> is distinctive in its strongly rhizomatous or suckering habit, erect inflorescences, leaf margins with three to six teeth on distal cm, and preference for basic or neutral soils. <i>Amelanchier humilis</i> was considered to be conspecific with <i>A. spicata</i> by G. N. Jones (1946). Occurrence of <i>A. humilis</i> in Saskatchewan, Kansas, and Nebraska is questionable, as no specimens were seen to confirm its presence there.</p><!--
--><p>M. L. Fernald (1950) reported hybrids between <i>Amelanchier humilis</i> and <i>A. arborea</i>, <i>A. bartramiana</i>, and <i>A. spicata</i>. The authors have observed putative hybrids with <i>A. amabilis</i>.</p>
