Grand Hawthorn (Crataegus grandis Ashe)

POWO considers this species to be a hybrid Crataegus √ógrandis Ashe and furthermore considers it a synonym of Crataegus √ódisperma Ashe and reports a range neither containing nor contained within the range reported by BONAP. We have not yet investigated this situation; for now we have stuck with BONAP's scheme.
