Malus sylvestris, the crab apple, is a species of the genus Malus, native to Europe. Its scientific name means "forest apple", and the truly wild tree has thorns.
In the past, M. sylvestris was thought to be an important ancestor of the cultivated apples (M. domestica), but these have now been shown to have been originally derived from the central Asian species M. sieversii.
The flowers are hermaphrodite and are pollinated by insects. Its leaves are food of the caterpillars of the Twin-spotted Sphinx (Smerinthus jamaicensis) and possibly the Hawthorn Moth (Scythropia crataegella). (info source: wikipedia.org)
