Almost certainly a hybrid of a species in Subsect. Fortunea. The type of this species was raised at Edinburgh from seed as Forrest 16463 (which is a species of Acer). The type sheet is annotated with the remark that it may have been a chance hybrid between R. wardii and R. vernicosum, a hybrid that does occur in the wild. Royal Horticultural Society (1997)
