Rosaceae or the Rose Family includes 91 genera and about 4828 species. Some of the well-known members include Prunus, Cotoneaster, Alchemilla, Sorbus, Rubus, Rose, Meadowsweet, and Firethorn. The Rosaceae family members are usually herbs, shrubs, or trees. Some are evergreens but most are deciduous.
They are diverse but the majority are from the northern hemisphere and none from Antarctica. Rosaceae family also has many edible fruits such as almonds, pears, apples, raspberries, apricots, quinces, peaches, and strawberries.
Rosaceae member plant leaves are generally arranged spirally and sometimes opposite. They are either simple or pinnately compound. Usually, they have serrate edges and paired stipules. Rosaceae flowers are radially symmetrical and have five sepals and petals and spirally arranged stamens. They are hermaphroditic. Fruits are follicles, capsules, nuts, drupes, or achenes. Many fruits are edible and consumed. But the seeds contain Amygdalin which releases cyanide.
