Abstract

In the present study we report somatic chromosome numbers of four Nepeta species including: N. laxiflora (2n=18), N. depauperata (2n=34), N. archibaldii (2n=16) and N. dschuparensis (2n=18). These species are endemics of Iran and the chromosome number for these species are reported here for the first time.
