The karyotype asymmetry/symmetry of a taxon (eight populations) from different geographic sites of Zhumeria genus is presented. The ploidy level between and within populations was 4 x. According to intra-chromosomal asymmetry, population Z ₂ had the most symmetrical karyotype and population Z ₇ had the most asymmetrical evolutionary karyotype among the populations. In terms of the Stebbins system, the karyotype of populations can be classified in 1A, 2A and 2B classes. The results of analysis of variance revealed significant differences between the populations based on nine karyotypic traits (p < 0.05 and p < 0.01). Cluster analysis showed that the populations of Zhumeria majdae have been grouped in separate clusters. The results seemed to provide enough genetic evidence to identify different populations and useful data to clarify the interspecific relationships. Detailed karyotype analysis allows us to group the different populations and to postulate relationships among them.
