Crataegus sororia occurs around Rome, Georgia, where it is common, in adjacent areas of Alabama, and in Aiken County, South Carolina.
Most similar to Crataegus aprica, C. sororia differs in leaf shape (proportionately wider), stamen number, and anther color. Beadle said that C. sororia is found south to Florida; no specimen from there was seen. The more or less tomentose inflorescence is a good recognition character.
