The Maloideae Claude Weber was the apple subfamily, a grouping used by some taxonomists within the rose family, Rosaceae. Recent molecular phylogenetic evidence has shown that the traditional Spiraeoideae and Amygdaloideae form part of the same clade as the traditional Maloideae, and the correct name for this group is Amygdaloideae. Earlier circumscriptions of Maloideae are more-or-less equivalent to subtribe Malinae or to tribe Maleae. The group includes a number of plants bearing commercially important , such as and , while others are cultivated as ornamentals.
In its traditional circumscriptionG. K. Schulze-Menz 1964. Reihe Rosales. in A. Engler's Syllabus der Pflanzenfamilien mit besonderer Berücksichtigung der Nutzpflanzen nebst einer Übersicht über die Florenreiche und Florengebiete der Erde, Gebrüder Borntraeger, Berlin this subfamily consisted exclusively of and small characterised by a pome, a type of accessory fruit that does not occur in other Rosaceae, and by a basal haploid chromosome count of 17 (instead of 7, 8, or 9 as in the other Rosaceae), involving approximately 28 genera with approximately 1100 species worldwide, with most species occurring in the temperate Northern Hemisphere.
An earlier intermediate classification expanded Maloideae to include four genera with dry non-pome fruit. These are Kageneckia, Lindleya, and Vauquelinia, which have a haploid chromosome count of 15 or 17, and Gillenia, which is Herbaceous plant and has a haploid chromosome count of 9.
A traditional circumscription of Maloideae includes the following genera:
