NEW CHROMOSOME COUNTS IN COUSINIA (ASTERACEAE, CARDUEAE) SECTIONS CYNAROIDEAE AND STENOCEPHALAE FROM IRAN

Meiotic chromosome counts are reported for eight species of Cousinia belonging to sections Cynaroideae Bunge and Stenocephalae Bunge. All counts are new to science. The new count for C. recurvata (sect. Stenocephalae), modified the previous count and shows a uniform basic chromosome number of x = 13 for the section. Our chromosome counts for the sect. Cynaroideae also support the unique basic chromosome number of x = 12 within the section.
