(a) Geographic characteristics of the Poyang Lake Basin. (b–f) Geographic distribution and median‐joining network of cpDNA haplotypes in Castanopsis tibetana (Ct1–Ct25), Schima superba (Ss1–Ss11), Cyclocarya paliurus (Cp1–Cp11), Sargentodoxa cuneata (Sc1–Sc25), and Eomecon chionantha (Ec1–Ec15), respectively. For each network, the size of circles corresponds to the frequency of each haplotype. Red dots indicate unsampled or extinct haplotypes. Each black line represents one mutational step that interconnects two haplotypes
