With over 2,500 species in more than 90 genera, the rose family (Rosaceae) is one of the major angiosperm families. While its taxonomy is somewhat contentious, the family is usually divided into four subfamilies based primarily on fruit type: Amygdaloideae, with drupes (fleshy stone fruits); Maloideae, with pomes (fruits in which the floral hypanthium becomes fleshy); Rosoideae, with achenes (dry fruits that do not open) or drupelets (small, aggregated drupes); and Spiraeoideae, with follicles (dry fruits that open on one side). The following is a list of some of the major genera and species in Rosaceae, arranged by subfamily.
