Haplotype network for ETS (a), gapC2 (b), PPR24 (c), PPR123 (d), cpDNA (e). Haplotypes from each taxon are denoted using the first letter of its population and species name (“Ba”, “Bc” and “Bw” refer to B. alternifolia, B. crispa, and B. × wardii fromt the BH population, respectively; while “Ta”, “Tc” and “Tw” refer to B. alternifolia, B. crispa, and B. × wardii from TJ population, respectively; “Da”, “Ja”, “Sc” and “Kc” refer to B. alternifolia from KD and JZ, and B. crispa from BS and KM, respectively. The number of mutations separating two adjacent haplotypes is shown by the number given on the connecting lines, the number is omitted for those with only one mutational step, and node size is proportional to the frequency of each haplotype. Colored circles represent haplotypes of different species as follows: green, yellow, dark green and dark blue represent B. crispa; pink, rose, orange and magenta represent B. alternifolia; blue and calamine blue represent B. × wardii. Small red circles represent hypothetical or unsampled haplotypes
