Fig. 2From: Peripatric speciation within Torreya fargesii (Taxaceae) in the Hengduan Mountains inferred from multi-loci phylogeographyHaplotype genealogies of the fourteen nuclear loci for T. fargesii var. fargesii and T. fargesii var. yunnanensis. The sizes of circles are proportional to the haplotype frequencies, and the mutation steps more than one are marked the corresponding number on each branch. The haplotypes (black circles) of T. taxifolia are used as the outgroupBack to article page
