Maloideae

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 fruits, such as apples and pears, while others are cultivated as ornamentals.

In its traditional circumscription[2] this subfamily consisted exclusively of shrubs and small trees 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.

[4] An earlier intermediate classification[5] expanded Maloideae to include four genera with dry non-pome fruit.

A traditional circumscription of Maloideae includes the following genera:[2] Intergeneric hybrids:[6] Graft chimeras:
