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

Other intergeneric hybrids within tribe Maleae that include "Sorbus" as one of the parents are: × Sorbaronia mitschurinii × "Sorbaronia mitschurinii, also known as Sorbaronia mitschurinii", is a domesticated species that was known until recently under the name "Aronia mitschurinii". It has been considered to be a group of cultivars of "Aronia melanocarpa", common ones including 'Viking' and 'Nero'. Genetic testing indicates it is likely a hybrid between "A. melanocarpa" and "Sorbus aucuparia" (mountain ash) that apparently originated in cultivation. It has been suggested that "Sorbaronia mitschurinii" is the product of Russian pomologist Ivan
