Malus (/ˈmeɪləs/ or /ˈmæləs/) is a genus of about 30–55 species of small deciduous apple trees or shrubs in the family Rosaceae, including the domesticated orchard apple (M. pumila). The other species are generally known as crabapples, crab apples or wild apples.
The genus is native to the temperate zone of the Northern Hemisphere.
Apple trees are typically 4–12 m (13–39 ft) tall at maturity, with a dense, twiggy crown. The leaves are 3–10 cm (1.2–3.9 in) long, alternate, simple, with a serrated margin. The flowers are borne in corymbs, and have five petals, which may be white, pink or red, and are perfect, with usually red stamens that produce copious pollen, and a half-inferior ovary; flowering occurs in the spring after 50–80 growing degree days (varying greatly according to subspecies and cultivar).
