A revision of some Korean Liparis (Orchidaceae) based on Molecular data.
THE genus Liparis Rich. (Orchidaceae) in Korea is comprised of seven taxa. Five of these, L. fujisanensis, L japonica, L. koreana, L. kumokiri, and L. makinoana, are restricted to eastern Asia. The specific delimitation of these five taxa is not clear due to the underlying morphological variation. To reexamine the taxonomic limits and relationships of these five taxa, nuclear ITS and chloroplast psbA-trnH, matK, trnS-G, trnLF DNA sequences were analyzed for 56 accessions from 34 populations of all Korean taxa including Japanese L. fujisanensis and two outgroups. A putative new taxon forming a monophyletic group was proposed by five species-specific nucleotides in the ITS region, and also by six species-specific nucleotides and three deletions in cp DNA. The new taxon forms a clade with L. japonica and L. makinoana in both ITS and cp DNA phylogenies. Liparis koreana has the same species-specific nucleotides at two sites of ITS region with Japanese L. fujisanensis. But in the combined cp DNA, L. koreana has four species-specific nucleotides, while Japanese L. fujisanensis has four species-specific nucleotides and one insertion. Korean L. fujisanensis, which grows on the rocks of Mt. Yumyoung, was identical to L. koreana, and different from Japanese L. fujisanensis, which grows on the trees, based on molecular data. This suggests that L. fujisanensis does not exist in the Korean peninsula.
