Discussion

Variety coccinea is found throughout the range of the species except for southern Quebec; it is the only variety found in the Appalachians south of Pennsylvania. An old report for Minnesota has not been confirmed. Crataegus albicans is a variant with particularly broad leaves and nearly glabrous inflorescences. Crataegus aulica Sargent perhaps belongs here. According to J. A. Macklin and J. B. Phipps (2002), much of the material named C. ellwangeriana Sargent [C. pedicellata var. ellwangeriana (Sargent) Eggleston] belongs to C. pennsylvanica Ashe.
