Sorbus pseudomeinichii of the location. The species is named after Glen Catacol where it was found and one of the two surviving plants is thought to be more than fifty years old. 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 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;
