Chromosome number reports and karyotype analysis of seven species from the flora of Iran

Seven plant species belonging to 5 genera of Apiaceae, Convolvulaceae, Fabaceae, Lamiaceae, and Solanaceae family were studied. The chromosome numbers for four taxa including Pimpinella aurea 2n=20, Convolvulus leiocalycinus 2n=24, Astragalus jesdianus 2n=16, and Salvia mirzayanii 2n=20 are reported for the first time and the chromosome number of Conium maculatum 2n=22, Ziziphora tenuior 2n=18 and Datura innoxia 2n=24 are reported in the flora of Iran for the first time. Karyotypic analyses of all species are presented.
