Discussion

Crataegus levis ranges from the southern Great Lakes area to southern New England, to Ohio, Pennsylvania, and in mountains to North Carolina.

Crataegus levis is often confused with the C. compta form of C. populnea; that taxon usually has slightly larger, more coriaceous leaves, with less acute lobes than C. levis. Crataegus levis is possibly a hybrid of C. macrosperma × C. pruinosa.
