Genetic diversity of populations of <i>Scutellaria indica</i>, <i>S. austrotaiwanensis</i>, <i>S. playfairii</i>, <i>S. tashiroi</i>, and <i>S. taiwanensis</i>.

Tajima’s D and Fu’s Fs were estimated based on 1000-repeat coalescent simulations in consideration of recombination. N is the number of sequences; H is the number of haplotypes; Hd is the haplotype diversity; π and θ are the nucleotide diversity estimated by pairwise differences and number of segregating sites, respectively. Chloroplast matK, which is monomorphic in every species, is excluded. S. taiwanensis (N = 31), which is monomorphic at loci CAD, CHS, and rpl32-trmL, and S. austrotaiwanensis, which is monomorphic at loci ndhF-rpl32 and rpl32-trmL, are not shown. *endemic to Taiwan; †members of the indica group. Detailed information about the genetic diversity of each sample population is given in Table S4.
