the apples, is a genus of about 30–35 species of small deciduous trees or shrubs in the family Rosaceae. Other studies go as far as 55 species [3] including the domesticated Orchard Apple, or Table apple as it was formerly called (M. domestica, derived from M. sieversii, syn. M. pumila). The other species and subspecies are generally known as "wild apples", "crab apples", "crabapples" or "crabs".
The genus is native to the temperate zone of the Northern Hemisphere, in Europe, Asia and North America.
The leaves are 3–10 cm 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 an inferior ovary.
