Taxonomy

The position of the genus Holodiscus in the family Rosaceae has changed over the last century as more detailed studies have been carried out. It has been place in subfamily Maloideae, but recent molecular evidence places all of (the former) subfamily Maloideae inside the subfamily Amygdaloideae.^[4]
