Map of the geographical distribution, and the phylogenetic network of cpDNA haplotypes of R. crenulata. a A map showing the sites of sampled populations and the geographical distribution of haplotypes. Pie charts show the proportion of haplotypes within each population. Dashed line on the map indicates the distribution area of R. crenulata. b NETWORK-derived genealogic relationships of cpDNA haplotypes. Different colors represent different haplotypes
