Abstract: This paper reported karyotypes of six taxa of Bupleurum L. and discovered that new taxon in Wulimu, Zhao dong county had the same karyotype as B. falcatum in Japan, which was called temporarily to Wulimu population. Karyotype formulas of those taxa are showed as follows:B. komarovianum Lincz. 2n=8=2m+6sm(2SAT). B. scorzonerifolium Willd. 2n=12=20m+12. B. chinense DC. 2n=24=14m+10sm(2SAT). B. bicaule Helm 2n=32==10m(2SAT)+2sm. B. longiradiatum Turcz. 2n=12=10m(2SAT)+2sm. Wulimu population 2n=26=16m+10sm (2SAT). It was discussed that evolutionary relationchips among those taxa of Bupleurum L. in Northeast China based on karyotypic characters.

Key words: Bupleurum L., Karyotype, Cytotaxonomy
