Sorbus arranensis rupicola") which is still found on Holy Isle. This hybrid species interbred with the rowan/mountain ash ("Sorbus aucuparia") to produce "S. arranesis". The bastard mountain ash ("Sorbus pseudofennica") arose from a further cross between "S. arranensis" and the mountain ash ("S. aucuparia"). Smart showed by using physical characteristics that the species were separate and not a result of random variation. Some overlap does however occur and this suggests that some hybridising may occur between the two species. Sorbus arranensis Sorbus arranensis, sometimes referred to as the Scottish or Arran whitebeam is a species of plant in the family Rosaceae. It
Rowan by some commentators. In the Canadian provinces of Newfoundland and Labrador and Nova Scotia, this species is commonly referred to as a "dogberry" tree. In German, "Sorbus aucuparia" is known as the "Vogelbeerbaum" ("bird-berry tree") or as "Eberesche". The latter is a compound of the name of the ash tree ("Esche") with what is contemporarily the name of the boar ("Eber"), but in fact the continuation of a Gaulish name, "eburo-" (also the name for a dark reddish-brown colour, cognate with Greek "orphnos", Old Norse "iarpr" "brown"); like "sorbus", "eburo-" seems to have referred to the colour of the berries;
