Reverchon's Hawthorn (Crataegus reverchonii Sarg.)

For reasons unclear to us, BONAP has merged this species into cockspur hawthorn (Crataegus crus-galli). We could not find any authorities recognizing these as a single species. FNA and POWO list this species as occurring farther east, to Georgia and Tennessee, with POWO listing it as occurring in Delaware as well. This may reflect differences in which populations are considered part of the taxon referred to by this name. The Crataegus genus is messy and subject to much uncertainty and frequent reclassifications, and we have yet to make sense of these discrepancies.
