Discussion
Crataegus sargentii is mainly from Alabama, extending west to central Mississippi, eastwards with scattered records from Georgia, and south to the panhandle of Florida; it is locally common. Anthesis is three weeks later in the Alabama canyonlands than on the Gulf Coast. The species is most similar to C. gilva; the latter has narrower leaves and smaller pomes. Occasional more deeply incised forms may resemble other species to some extent; they will usually retain the characteristic overall leaf shape of the species.
