Hybridisation events between at least one member of genus
Aria and at least one member of at least one different genus in the subtribe
Malinae have led to a complex of apomictic microspecies in Europe and western Asia, whose classification has been unclear for decades. Traditionally, they and their parent genera were commonly treated as subgenera of a large genus
Sorbus s.l., however, this system was found to be
polyphyletic. In 2017, a system was proposed and then widely adopted that classifies these microspecies into separate genera according to their parentage, and elevates all former subgenera of
Sorbus s.l into genera. •
