Sampling site with genetic boundary of Opisthopappus populations and distribution of haplotypes. a Distribution of 75 haplotypes detected within and among 24 populations of O. longilobus and O. taihangensis. Red circles refer to O. taihangensis populations and blue circles refer to O. longilobus populations, respectively. For population abbreviations, see Table 1 for details. b Results of the BARRIER analysis showed that the spatial separation of Opisthopappus populations. Delaunay triangulation and detected barrier (thick red line) separating O. longilobus and O. taihangensis in Taihang Mountains. Bootstrap values over 1000 replicates using Nei’s genetic distances
