Morus australis, also called Korean mulberry[3] and Chinese mulberry,[4] is a flowering plant species found in East and Southeast Asia.

M. australis is a host plant for Calinaga buddha (Freak).

[6] Some authorities claim that M. australis is a synonym of Broussonetia papyrifera, the paper mulberry.,[7] others deny this, claiming that M. australis and B. papyrifera are separate species within the Moraceae family.

[citation needed] The majority of Morus species should be considered subspecies of M. alba,[citation needed] whether M. australis is a separate species, or a subspecies of M. alba has not been established.

[citation needed] Millennia of cultivation of Morus species, and easy hybridisation between Morus species, has resulted in problems for classification.
