Chromosome number, karyotype, Lamiaceae, Nepeta, endemics, Iran


The genus Nepeta L. is one of the most important genera of Lamiaceae family with 300 species in Asia and Europe. There are 80 species in Iran, out of which 39 species have been reported as endemics to Iran. In this study, the chromosome counts of eight Nepeta species were investigated and the karyotypic diversity among these species was studied. The examined species belong to N. cephalotes species group, namely N. eremokosmos Rech.f., N. gloeocephala Rech. f., N. cephalotes Boiss., N. pungens (Bunge) Benth., N. ispahanica Boiss., N. mahanensis Jamzad & Simonds, N. hormozganica Jamzad, and N. denudata Benth. collected from different habitats in Iran. These studies were performed on the root meristems using squash technique. Results showed the same chromosome number, 2n = 2x=18 for all species studied. The base chromosome number for the above mentioned species are x = 9.
