Sorbus pseudomeinichii Sorbus pseudomeinichii Sorbus pseudomeinichii, known as false rowan and Catacol whitebeam, is a rare tree endemic to the Isle of Arran in south west Scotland. It is believed to have arisen as a hybrid of the native rowan ("Sorbus aucuparia") and the cut-leaved whitebeam ("Sorbus pseudofennica") which is in turn a rowan/Arran whitebeam ("Sorbus arranensis") hybrid. Only two specimens of the Catacol whitebeam are known, making it the rarest tree in Scotland and also the United Kingdom. A third was recorded as a sapling but is believed to have been destroyed by deer. A seedling has also been grown in
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;
