This study represents chromosomal data for eight species of four genera from Apiaceae. The karyotype analysis in this research was performed using the squash technique on mitotic metaphase chromosomes. Out of the eight species studied, five are new reports (Dorema aucheri, Ducrosia assadii, Ferula oopoda, F. pseudalliacea, and F. sphenobasis), while three counts confirm (Dorema ammoniacum, Ducrosia anethifolia, and Smyrnium cordifolium) the findings of the previous studies. All species have a basic chromosome number of x=۱۱. Dorema ammoniacum and D. aucheri have only one submetacentric chromosome while in Ferula pseudalliacea, about half of the chromosomes were submetacentric. In Ducrosia anethifolia, D. assadii, Ferula oopoda, F. sphenobasis, and Smyrnium cordifolium all chromosomes are metacentric.
