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.

Malus coronaria fruit clings to the branches on clustered stems long after the leaves have fallen. "Malus coronaria" var. "coronaria"<br> "Malus coronaria" var. "dasycalyx" Pehr Kalm, who was one of the twelve men whom Linnaeus called his apostles and sent forth to explore the vegetable world, wrote from America: Malus coronaria Malus coronaria, also known by the names sweet crabapple or garland crab, is a North American species of "Malus" (crabapple). It grows primarily in the Great Lakes Region and in the Ohio Valley, with outlying populations as far away as Alabama, eastern Kansas, Long Island, and Ontario. "Malus coronaria" often is
