Discussion
Crataegus ashei occurs from Louisiana to Alabama and is apparently scarce.
Crataegus ashei has often been confused with both C. triflora (ser. Triflorae) and C. harbisonii; it differs from C. triflora in its different growth habit with branching more or less layered and leaves smallish, flowers smaller, stamens 20–24, and leaves usually more coriaceous and shiny with lobes absent. Crataegus ashei is more similar to C. harbisonii, mainly differing in being smaller in its vegetative parts, invariably lacking reproductive side shoots of the season, and by having entire leaves.
