In this study, the chromosome numbers of six Iranian taxa belonging to tribe Cardueae were counted. The chromosome numbers in Jurinea cartilaginea Mozaff. ۲n=۳۰, J. carduiformis (Juab. & Spach) Boiss. ۲n=۳۴, Aegopordon berardioides Boiss. ۲n=۳۴, Nikitinia leptoclada (Bornm. & Sint.) Iljin ۲n=۳۰, Centaurea amadanensis Schultz-Bip. var. gymnoclada (Jaub. & Spach) Wagenitz ۲n=۱۸ and Cousinia argentea Mehregan & Assadi ۲n=۲۶ were determined. Of the chromosome counts reported four are new to the world. Based on this study, three taxonomic changes are confirmed and a new suggestion is presented here.
