    were considerably lower than those of P. inflatum. However, when samples were pooled, P. stenophyllum harbored higher genetic variation than P. inflatum, which is due to higher among-population genetic differentiation in the former species compared with the latter (FST=0.636 vs. FST=0.165). Our data suggest that populations of P. stenophyllum have been mainly founded by a single seed or rhizome (through river water) or by a few seedsseedsSubject Category: Anatomical and Morphological Structures

    , whereas populations of P. inflatum would have been established through multiple, repeated seedling recruitment. Moderate levels of genetic diversity in a population of P. stenophyllum located at the foot of the Baekdudaegan Mountains and in all the populations of P. inflatum are consistent with the previous hypothesis that these mountains served as a glacial refugium for many boreal species of the Korean Peninsula.
