|discussion=<p><i>Crataegus ursopedensis</i> is restricted to and locally common in the Bear's Paw Mountains (Montana) and the Cypress Hills (Alberta and Saskatchewan).</p><!--
--><p><i>Crataegus ursopedensis</i> can have strikingly large, deeply incised and sharply lobed, short-shoot leaves; they are often smaller and may then be difficult to differentiate from those of <i>C. rubribracteolata</i>. Compared to the latter, the thorns are often longer, the inflorescences more open, the petioles proportionately longer, the bracteoles paler and, significantly, the pyrene sides more nearly plane. <i>Crataegus ursopedensis</i> is strikingly distinct within ser. Rotundifoliae and perhaps does not belong there.</p>
