Notes: The treatment here does not follow the taxonomy in FNA Rosaceae. The extensive overlap in morphology among putative Amelanchier taxa makes writing a diagnostic key among them untenable. At the species level, differences in ploidy level have been documented, however finding morphological traits that reliable distinguish among these species appears inconclusive at this time.
