It was revaluated about taxonomic position of Bupleurum latissimum Nakai (Apiaceae) by the cluster analysis, the principal component analysis, and the discriminant analysis. Its diagnostic characteristics include bracteole length longer than umbellules, 16-21 pedicel numbers, plant with evergreen leaves, chromosome number 2n = 16 and cauline leaves with auriculate base. It is morphologically similar to B. euphorbioides in having ovate bracteoles, 16-21 pedicel numbers, chromosome number 2n = 16, and cauline leaves with auriculate base, but distinguished from B. longiradiatum with having linear bracteoles, 7-15 pedicel numbers, and chromosome number 2n = 12. Morphological characters support that Bupleurum latissimum Nakai is a Korean endemic species.
