Formerly placed in the family Malaceae (now part of Rosaceae), e.g. Flora of New South Wales Vol. 1 (1990). A number of subspecies of Crataegus monogyna have been recognized with two of these recorded in Australia, but it is very doubtful that any division of material naturalized in Australia can be sustained. However, material appears closest to subsp. nordica Franco.
