“…Presently, eight species are recognized in Korea, constituting nearly half of the 15 species in subgenus Aizoon . This includes the recent recognition of P. latiovalifolius 16 , previously misreported as P. latiovalifolium 17 . The identified species are P. aizoon , P. ellacombeanus , P. kamtschaticus , P. middendorffianus (Maxim.)…”

Phedimus latiovalifolius (Y.N.Lee) D.C.Son & H.J.Kim is exclusively distributed in the high mountains in the Korean Peninsula, mainly along the Baekdudaegan mountain range. Despite its morphological and distributional distinction from other Phedimus Raf. species, its taxonomic identity and phylogenetic relationship with congeneric species remain unclear. This study employs genotyping-by-sequencing-derived genome-wide single nucleotide polymorphisms to establish the monophyly of P. latiovalifolius and its relationship with closely related species. Genetic diversity and population differentiation of P. latiovalifolius are also assessed to provide baseline genetic information for future conservation and management strategies. Our phylogenetic analyses robustly demonstrate the monophyletic nature of P. latiovalifolius, with P. aizoon (L.) ‘t Hart identified as its closest sister lineage. There is no genetic evidence supporting a hybrid origin of P. latiovalifolius from P. aizoon involving either P. ellacombeanus (Praeger) ‘t Hart or P. kamtschaticus (Fisch.) ‘t Hart. Population genetic analyses reveal two major groups within P. latiovalifolius. A higher genetic variation is observed in P. ellacombeanus than in the congeneric species. Notably, most of the genetic variation exists within P. latiovalifolius populations. Given its distribution and the potential role of Baekdudaegan as an East Asian Pleistocene refugia, P. latiovalifolius could be considered rare and endemic, persisting in the refugium across glacial/interglacial cycles.

“…) was conserved in Dr. Lee's personal herbarium (Korea Plant Research Institute, KPRI). After Dr. Lee passed away 22 June 2008, all specimens including types at KPRI were donated by his family to the National Institute of Biological Resources (KB; herbarium acronyms according to Thiers 2018+) on 2 June 2009 (Son et al 2016). On that basis, after examining herbarium specimens of KB, we found three specimens (NIBRVP0000187061!, NIBRVP0000187062!, and NIBRVP0000187063!)…”
