|discussion=<p>Variety monogyna differs from var. lasiocarpa (Lange) K. I. Christensen in the absence of villous abaxial leaf surfaces and inflorescences. Variety monogyna is distributed throughout the area of the species; var. lasiocarpa primarily occurs in the Balkan, Iranian, and Mediterranean areas, and is most common in Greece.</p><!--
--><p>Variety monogyna is locally common in the Pacific Northwest and adjacent Canada, as well as from the Great Lakes to the Atlantic. The variety hybridizes in North America with the diploid species <i>Crataegus</i> suksdorfii and rarely with <i>C. punctata</i>. The hybrid with <i>C. laevigata</i>, C. ×media Bechstein, is well known in the wild in Europe; only its cultivars are seen in North America.</p>
