The main range of Crataegus mira is the Florida panhandle to central Georgia, but it extends to the Carolinas and Alabama; the species is locally common.

Crataegus mira is most similar to C. aprica, C. sororia, and especially C. leonensis, but differs from them in its wider and often larger leaves, thinner inflorescence indumentum (than C. sororia), and larger flower size. The illustration depicts an unusually formed sessile-glandular bracteole.
