|discussion=<p><i>Crataegus populnea</i> occurs from Wisconsin to New York, to Ohio, and Virginia; it is common at least from southern Ontario to Pennsylvania. Dubious specimens from Georgia and South Carolina have small leaves and are only differentiated from <i>C. iracunda</i> (ser. Tenuifoliae) by their more coriaceous nature. Being out of range for <i>C. populnea</i>, they may represent an odd form of <i>C. iracunda</i>.</p><!--
--><p><i>Crataegus</i> compta is a variant with more or less pyriform-oblong pomes. <i>Crataegus populnea</i> might be mistaken for <i>C. macrosperma</i> but it has more coriaceous leaves, usually significantly larger in the area of sympatry, and a harder fruit.</p>
