Discussion

Crataegus pexa is widely distributed in North Carolina with a few records from South Carolina and Georgia. The similarities of C. colonica to C. pexa have been noted under that species. Crataegus pexa differs in its often slightly incised and more prominently toothed leaf margins, generally lower plant stature, relatively wider leaf blades, suborbicular fruits, longer and abundant thorns, and strongly flexuous twigs.
