Nested cladogram of 32 chloroplast haplotypes in Scutellaria baicalensis and two haplotypes in Scutellaria rehderiana. The color of haplotypes refers to Fig. 1. The bold and italic numbers besides haplotypes represent the number of wild and cultivated individuals with certain haplotype, respectively. Open small circles represent inferred interior nodes that were absent in the samples. Each branch indicates one mutation.
