Rosaceae (the rose family) is a medium-sized family of flowering plants, including about 2830 species in 95 genera.〔(【引用サイトリンク】title=Angiosperm Phylogeny Website )〕 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. The Rosaceae family includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range, but are most diverse in the Northern Hemisphere. Several economically important products come from the Rosaceae, including many edible fruits (such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, loquats, and strawberries), almonds, and ornamental trees and shrubs (such as roses, meadowsweets, photinias, firethorns, rowans, and hawthorns).〔 ==Distribution== The Rosaceae have a cosmopolitan distribution (found nearly everywhere except for Antarctica), but are primarily concentrated in the Northern Hemisphere in regions that are not desert or tropical rainforest.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rosaceae」の詳細全文を読む スポンサード リンク
