Hedlundia pseudofennica

Hedlundia pseudofennica, also called Arran service-tree^[2] or Arran cut-leaved whitebeam, is a species of plant in the family Rosaceae. Endemic to the Isle of Arran in Scotland, it is threatened by habitat loss.^[1] It is thought to be a naturally occurring hybrid between H. arranensis and Sorbus aucuparia, probably with additional backcrossing with S. aucuparia. Hedlundia arranensis is itself a hybrid between Aria rupicola and S. aucuparia. Apomixis and hybridization are common in some groups of Sorbus species.^[3]
