|discussion=<p><i>Crataegus magniflora</i> ranges through the southern Great Lakes area from Illinois and Wisconsin to Pennsylvania and Massachusetts. Two forms occur, one with a more nearly truncate leaf base, which is more common in Ontario, and a more fulleriana-like form, which is most common westward.</p><!--
--><p>The leaf of <i>Crataegus magniflora</i> is most similar to that of <i>C. coccinea </i>var.<i> coccinea</i> but differs in usually being a little larger, often relatively wider (length/width sometimes equal to 1.1), and in the base being more truncate to more or less cordate than is usual in <i></i>var.<i> coccinea</i>. <i>Crataegus magniflora</i> was often identified as C. corusca Sargent before it was recognized that the latter represented a putative interserial hybrid of ser. Coccineae × ser. Molles origin.</p>
