It is uncommonly found in Ireland and the United Kingdom, with an entire British population estimated at about 600[3] individuals. DescriptionSorbus anglica grows as a small tree or shrub, often with multiple stems. The leaves are broader than most other Sorbus, with lobes whose bases are incised up to one third of the way to the midrib.[4]DistributionSorbus anglica is found in several widely scattered sites in SW England, Wales, and around Killarney in SW Ireland.[5]Ecology and evolutionSorbus anglica is usually found growing on cliffs, quarries and rocky hillsides. It appears to be indifferent to soil pH. Occasional specimens are known from oak woodland. Research suggests Sorbus anglica arose from a cross between Sorbus porrigentiformis and Sorbus aucuparia.[6]References1. ^Beech, E. & Rivers, M.C. 2017. Sorbus anglica.
