Malus sylvestris to most European countries. It occurs in a scattered distribution pattern as single individuals or in small groups. In the past "M. sylvestris" was thought to be the most important ancestor of the cultivated apple ("M. pumila"), which has since been shown to have been originally derived from the central Asian species "M. sieversii". However another recent DNA analysis confirms that "M. sylvestris" has contributed significantly to the genome. The study found that secondary introgression from other species of the genus "Malus" has greatly shaped the genome of "M. pumila", with "M. sylvestris" being the largest secondary contributor. It also
Malus baccata by 4–6. Petals are white and egg-shaped, approximately 2–2.5 cm (0.8-1.0 inches) long. Fruits are red to yellow and spherical, only about 1 cm (0.4 inches) in diameter; they form dense clusters and resemble cherries from a distance. Flowering occurs in spring, with fruits appearing in September–October. The subordinate taxa include "Malus baccata" is used as ornament for its flowers and fruit. Fruits are edible and are eaten fresh or dried. As one of the tallest and most resistant to cold and pest species of its genus, "M. baccata" is used for experimental breeding and grafting of other crabapples and
