- There is a great deal of confusion about the species of Morus to which Unryu, the Contorted Mulberry, is linked. Some list it as M. bombycis Unryu, however the RHS Dictionary of Gardening equates M. bombycis with M. alba, and indeed some authorities (e.g., Missouri Botanical Garden) use the name M. alba Unryu, and some equate this name with M. alba Tortuosa. Contorted Mulberry is also listed as M. australis Unryu.
- Unryu: apparently means twisted in Japanese (Jacobson, 1996).
