Malus sylvestris s.l.
These are small trees of hedgerows, scrub, copses, roadsides and rough ground, usually occurring as single trees. 0?380 m in Swindale (Westmorland).
This map covers both the native M. sylvestris sens. str. (Crab Apple) and the alien M. domestica (Apple) and therefore equates to the map in the 1962 Atlas. Confirmed records of both taxa were mapped by Perring & Sell (1968). The two species hybridise and seem to be connected by a range of intermediates, which are included on the map. It can be difficult to separate native and alien populations, and all records are mapped as if they are native.
European Temperate element; widely naturalised outside its native range.
