  • Five species of the genus Leontopodium are recognized in Korea, but their taxonomic positions have been controversial. To clarify the taxonomic entity of these Korean species, we examined their morphological characters based on herbarium specimens and field observations. Valuable distinguishing characters for identification included the plant height, the basal shape of cauline leaves, the type and position of inflorescence, the types of hairs, the presence of leaves at the anthesis, and hairs on the phyllaries. Based on our observations, we were able to determine the taxonomic relationships between L. japonicum and its relatives, L. coreanum and L. hallaisanense. We also included the morphological characters of L. seorakensis in continuous variations of L. leiolepis, which we treated as synonyms. Consequently, we classified these Korean Leontopodium species into four taxa - L. coreanum var. coreanum, L. coreanum var. hallaisanense, L. leiolepis, and L. leontopodioides - with appropriate descriptions and illustrations.

  • Leontopodium seorakensis (Asteraceae), a new species from Mt. Seorak National Park in central Korea is described and illustrated. Its taxonomic history, distribution, habitats, and diagnostic characteristics are discussed and contrasted with those of the closely related L. japonicum Miquel and L. leiolepis Nakai.

  • The somatic chromosome number of four Korean species of Leontopodium were investigated. The chromosome number of L. leiolepis (2n = 24) is reported here as for the first time. The chromosome number of L. japonicum (2n = 28) is not varied among the 3 populations on the Korean Peninsula, but that condition is different from the previous reports for Korea (2n = 26) and Japan (2n = 21, 26). L. hallaisanense and L. japonicum, both of which are in sect. Nobilia and similar to each other in gross morphology, have the same chromosome number of 2n = 28. On the other hand the chromosome number of Korean L. leontopodioides (2n = 24) is different from that in Russian reports (2n = 26). The chromosome numbers of all Korean species of the genus Leontopodium could be inferred as tetraploid or aneuploid.
