ABSTRACT
The somatic chromosome numbers of the Korean species of Senecio L. and two related genera are investigated here. Three different chromosome numbers were found: 2n = 40 in Senecio argunensis Turcz., S. nemorensis L., S. vulgaris L., Tephroseris flammea (DC.) Holub and 2n = 44 in T. phaeantha (Nakai) C. Jeffrey & Y.L. Chen. and 2n = 48 in Sinosenecio koreanus (Kom.) B. Nord., T. kirilowii (Turcz. ex DC.) Holub and T. pierotii (Miq.) Holub. The chromosome numbers of Sinosenecio koreanus (Kom.) B. Nord., Tephroseris flammea (DC.) Holub and T. phaeantha (Nakai) C. Jeffrey & Y.L. Chen. were different from those in previous reports.
