Ribes ussuriense (common name - Korean black currant) is an Asian species of Ribes (currant), first described in 1906 by Edward Janczewski[1][2] (in 1904 the name alone was published)[3][4] The species epithet, ussuriense, means that the species comes from Ussuri.
It is considered to be a synonym of Ribes procumbens by Plants of the World Online,[1] which follows Chang, Kim & Chang (2014, 2021).[5][6] However, it is considered to be a separate species by Russian authorities,[7] and by the Korean National Species List (국가종목록).[8]
