The genus Docynia has been shown to be nested within Malus in molecular phylogenies. The genus Malus is subdivided into eight sections (six, with two added in 20). The centre of the fruit contains five carpels arranged star-like, each containing one or two seeds.Ībout 42 to 55 species and natural hybrids are known, with about 25 from China, of which 15 are endemic. The fruit is a globose pome, varying in size from 1–4 cm ( 1⁄ 2– 1 + 1⁄ 2 in) in diameter in most of the wild species, to 6 cm ( 2 + 1⁄ 4 in) in M. sylvestris sieversii, 8 cm (3 in) in M. domestica, and even larger in certain cultivated orchard apples. Several Malus species, including domestic apples, hybridize freely. Many apples require cross-pollination between individuals by insects (typically bees, which freely visit the flowers for both nectar and pollen) these are called self-sterile, so self-pollination is impossible, making pollinating insects essential.Ī number of cultivars are self-pollinating, such as 'Granny Smith' and 'Golden Delicious', but are considerably fewer in number compared to their cross-pollination dependent counterparts. 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). ![]() The leaves are 3–10 centimetres ( 1 + 1⁄ 4–4 inches) long, alternate, simple, with a serrated margin. Apple trees are typically 4–12 metres (13–39 feet) talI at maturity, with a dense, twiggy crown.
