蔷薇科（学名：Rosaceae）约有124属3300余种，广布与全球，以温带居多；中国约有55属1000余种。

Rosaceae (the rose family) is a medium-sized family of flowering plants, including about 2830 species in 95 genera.

The name is derived from the type genus Rosa. Among the most species-rich genera are Alchemilla (270), Sorbus (260), Crataegus (260), Cotoneaster (260), Rubus (250), and Prunus (plums, cherries, peaches, apricots, and almonds) with about 200 species. However, all of these numbers should be seen as estimates – much taxonomic work remains.
