Chromosome numbers of 36 vascular plants in South Korea

Abstract

Variation or constancy in the chromosome number, within taxa of different categories, proves to be important characters for taxonomic groupings. To expand the current knowledge on somatic chromosome numbers of South Korean vascular plants, chromosome counts were made for 36 species (27 genera of 16 families). New chromosome numbers compared to previous studies were counted in Sedum oryzifolium, Cinnamomum japonicum, Lysimachia clethroides, and Chrysosplenium flagelliferum, respectively. Among studied species, the diploids prevail. In addition, Eupatorium lindleyanum, L. clethroides, and Lysimachia mauritiana showed polyploidy.
