Bunium is unusual in Apiaceae in having a variable cotyledon number and broad infrageneric dysploidy. To test the monophyly of the genus, phylogenetic relationships among 39 Bunium species were investigated with DNA sequence data from nuclear (nrITS) and plastid (psbA-trnH intergenic spacer) regions. Several other taxa with a similar ecology and geography were also included in the analyses. Our results suggest that Bunium is not monophyletic. Bunium spp. in the eastern part of the study area are more closely related to the Central Asian genera Elaeosticta, Galagania, Hyalolaena, Mogoltavia and Oedibasis than to those in the western part. Our study revealed that molecular, morphological (cotyledon number and width of fruit commissure) and karyological data reveal similar patterns in the taxa studied.
