A short note on the taxonomic identity of Wasabia koreana Nakai (Brassicaceae)

This study was undertaken to resolve several systematic issues concerning the distribution, nomenclature, and local name of Wasabia koreana. A careful reexamination of the type specimen of W. koreana in TI as well as critical morphological comparison with the related taxa, Cardamine yezoensis and W. japonica, revealed that the W. japonica specimens from Ulleung Island had long been misidentified as W. koreana, resulting in the usage of the same local name for the two distinct taxa. An detailed review for the Cardamine pseudowasabi, a recently proposed name for the misplaced W. koreana, is provided.
