  1. The table considers data presented in this study as well as previous studies [19, 21]. IS-DS = Number of specimens with indehiscent versus specimens with dehiscent sporangia collected in this region. cpHG = cpDNA diversity measured by the number of haplotype groups. cpHT = cpDNA diversity measured by the number of haplotypes. The first number corresponds to the number of haplotypes found in specimens with indehiscent sporangia, whereas the second number represents the number of haplotypes found in specimens with dehiscent sporangia. * One haplotype group is exclusive or nearly exclusive to this region.
