Rosaceae

n. chronic skin disorder characterized by red blemishes on the nose and forehead (Medicine)

The Rosaceae or rose family is a large family of plants, with about 3,000-4,000 species in 100-120 genera. Traditionally it has been divided into four subfamilies: Rosoideae, Spiraeoideae, Maloideae, and Amygdaloideae. These subfamilies are primarily diagnosed by the structure of the fruits, although this approach is not followed universally. Recent work has identified that the traditional four subfamilies are not all monophyletic, but the structure of the family is still awaiting complete resolution.
