چکیده

عدد کروموزومی هشت گونه از جنس Cousinia   متعلق به دو بخشه Cynaroideae Bunge و Stenocephalae Bunge  برای اولین بار گزارش می‌گردد. شمارش کروموزومی جدید انجام‌شده برای گونه C. recurvata از بخشه Stenocephalae، گزارش کروموزومی قبلی را اصلاح نموده و نشان می‌دهد که عدد کروموزومی منحصر به فرد در این بخشx = 13  می‌باشد. اعداد کروموزومی گزارش شده در این مقاله در خصوص بخش Cynaroideae در واقع تاییدی بر وجود تنها یک عدد کروموزومی،x = 12 ، در این بخش است.
