  • Taxonomy: In the World Flora Online (WFO) the accepted name for this species is Berberis oiwakensis, with Mahonia oiwakensis as a synonym.  "This species has long been known by the name Mahonia lomariifolia, published by Takeda in 1917.  Under that name, it was considered to occur only in mainland China, while on Taiwan, a second species was found, known as M. oiwakensis. Modern taxonomic sources unite the two as a single species, but as the latter name was published a year earlier by Hayata, it has priority and is thus the accepted name" (Wikipedia).
