Phylogeny of Hepatica (Ranunculaceae) with special emphasis on Korean endemics.

Modern systematics or phylogenetics requires to analyze the phylogeny and the mechanism of speciation of plant groups through examination of all the characters by applying various methodologies which include classical external morphological examination, cytogenetic approach, chemical and molecular systematic approach, and numerical approaches. In addition, reconstruct the the phylogeny and reexamination of taxonomic category must be tested within world flora. Therefore, the aims of this research is to investigate the phylogeny and taxonomic position of genus Hepatica which comprises 9 species in the world, three of them are native to Korea, through applying various methodologies cited above. As a result from principal component analysis and phenetic analysis, H. maxima, endemic to Ullung island, is recognized as a distinct species and is the closest to H. asiatica. Korean Hepatica species are well distinguised from Japanes species. All the polyploids in this genus have pantocolpate pollen grains composed of 6 to 12 copi and diploids have tricolpate. Each polyploid is regarded as independently evolved and it is most probable that the polyploid is from allopolyploidization.
