Using genetic and morphological analyses, the relative contributions of neutral and non-neutral processes were explored to infer the evolutionary history of species of the series Sakawanum (genus Asarum), which shows significant clinal variation in calyx lobe length %K Cline %K QCT¨CFST comparison %K microsatellite marker %K genetic structure %K Asarum %K Aristolochiaceae %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5786219/
