--><p><i>Crataegus jesupii</i> ranges from Wisconsin to Connecticut, Ohio, and Pennsylvania.</p><!--
--><p>In Michigan, <i>Crataegus jesupii</i> is notable for its stipitate-glandular bracteoles. Forms with wider leaves, about as wide as long, are represented by C. filipes. An otherwise identical Ontario specimen has 20 stamens and would key out to <i>C. beata</i>.</p>
