Discussion
Crataegus prona ranges from Wisconsin and Indiana through Michigan to New York and Pennsylvania.
Crataegus prona is similar to C. populnea but with proportionately wider leaves and narrow pomes. When better known, it may prove the same as C. populnea. Crataegus gravis is a form with more oblong fruit and smaller leaves with sharper lobes.
