  • Aiming to determine the taxonomic identity of Gang-hwa-yak-ssuk as a cultivated plant, this study analyzes ITS sequences and compares their external morphologies with the genus Artemisia, which have a similar external morphology. Thus far, we have considered A. indica as the original plant of Gang-hwa-yak-ssuk, but Gang-hwa-yak-ssuk is better grouped with A. argyi, not A. indica, for the following reasons: Gang-hwa-yak-ssuk has the same characteristics as A. argyi in terms of the natural habitat, in that it is 1-bipinnately cleft or parted in the external morphology of its leaves, and because the white glandular trichome is distributed on the adaxial surface. This is in addition to the result of ITS sequence analysis. Therefore, we can define Gang-hwa-yak-ssuk as a cultivated plant that originates from A. argyi and not A. indica.

  • Objectives : Herbal medicines have been used a lot traditionally in Northeast Asia. In particular, various Apiaceae plants (Umbelliferae) are widely used for medicinal purposes among countries. However, the original species designated in each pharmacopoeia standards, are sometimes different and confuse. In this study, herbal medicines in the pharmacopoeia were analyzed for Apiaceae taxa to compare the taxonomic identity and different taxonomic opinions for each country based on their local flora and recent taxonomic studies. Methods : The scientific names of herbal medicines were analyzed origins from Pharmacopoeias of Republic of Korea, Democratic People's Republic of Korea, People's Republic of China, Taiwan, and Japan. Especially, we compared their local floras, international plant scientific name database, and recently published taxonomic studies to confirm the correct scientific name. Results : The analyzed apiaceous herbal medicines in pharmacopoeias were all 21 items and 39 taxa; the highest percentage, genus Angelica (21%) and roots including rhizomes (62%) the registered genera and medicinal parts, respectively. Eleven items were in all five country's pharmacopoeias. Four items were in more than two countries' pharmacopoeias. Six items were registered in only one pharmacopoeia. Conclusions : Our research provides necessary information, e.g., corrected scientific names of original species based on taxonomic species concepts, taxonomic reviews, and figures of medicines. These results will help in the understanding of the apiaceous taxa among the five countries' pharmacopoeias. Moreover, these extensive nomenclatural reviews of authentic apiaceous taxa will help for the next revision of Korea Pharmacopoeia.

  • Goodyera rosulacea, which is morphologically similar to G. repens, is described recently as a new species based on its distinct morphological characters such as rosette-formed leaves, short rhizome and habitat. To verify the taxonomic identity of G. rosulacea and its taxonomic relationship within Korean Goodyera taxa, sequences of the internal transcribed spacer (ITS) region of nuclear ribosomal DNA and the trnL region of cpDNA from 24 accessions including 1 outgroup accession were analyzed. Aligned sequences were analyzed using maximum parsimony and distance method, and the taxonomic identity and the taxonomic relationships among the related taxa were estimated by the existence of private marker gene and the phylogenetic tree of the aligned sequences. Molecular data indicate that G. rosulacea gas several private marker genes and shows monophyly in phylogenetic trees of both ITS and trnL sequences. the pairwise distance between G. rosulacea and the orher taxa of Korean Goodyera was 3.49-6.68% for ITS region and 5.05-9.53% for trnL region, indicating that G. rosulacea could be treated as an independent species. Therefore, our molecular data support the taxonomic of G. rosulacea as a distinct species of Korea. In phylogenetic trees, G. rosulacea formed same clade with G. repens, which has similar morphological characters with G. rosulacea, and showed the lowest pairwise distance with G. repens among Korean Goodyera taxa. These molecular data sugguested that G. rosulacea and G. repens are closely related taxa.

  • To confirm the taxonomic identity of taxa described by $L{\acute{e}}veill{\acute{e}}$, H. H. A, a French plant taxonomist, in the serial papers of Decades plantarum novarum based on the collections of Fathers Faurie and Taquet from the Korean peninsula, we examined the numerous references that contained taxonomic opinions about $L{\acute{e}}veill{\acute{e}}^{\prime}s$ taxa. Among them, 146 taxa were confirmed as conspecific with other existing taxa. Of them, 79 taxa, including Ajuga devestita, were listed as a synonym of only one species. Sixty-seven taxa, including Bidens robertianifolia, were listed as synonyms of two or more species according to taxonomists. Eight taxa, including Aconitum coreanum, were considered illegitimate names because of later homonym, or other problems. Five taxa, including Rhododendron hallaisanense, were treated either as distinct or conspecific taxa depending on taxonomists.

  • There are three carpet-like Codium species with a broadly expanded thallus reported from Korea and Japan: C. latum Suringar, C. tapetum Y. Lee, and C. tenuifolium Shimada, Tadano and J. Tanaka. During surveys of green algal diversity, we encountered a Codium species with carpet-like thalli from several sites on Jeju Island. To confirm the taxonomic identity of these specimens, we studied the morphological features and obtained rbcL gene sequences. The morphological and sequence data indicated that the carpet-like Codium specimens from Jeju are C. tenuifolium from Japan, but distant from Japanese C. latum. We propose that the carpet-like specimens from Jeju should be renamed C. tenuifolium, instead of C. tapetum or C. latum. C. tenuifolium is characterized by a tenuous, carpet-like and erect thallus with a very short and slightly compressed stipe arising from a discal holdfast, sub-pyriform and clavate utricles with a tumid and swollen apical head, and globular or sub-globular gametangia issued at the basal portion of the utricles.

  • Hainan is the second largest and southernmost island of China, and it harbors many species of the family Gracilariaceae. In this study, we conducted molecular and morphological analyses of gracilarian specimens collected from Hainan Island, to clarify their taxonomic identity and phylogenetic relationships. Five species of Gracilariaceae in Hainan were determined through maximum likelihood and Bayesian analysis of rbcL sequence data. Based on the phylogenetic trees and morphology, Hainan specimens were identified as three species of Gracilaria, one species of Gracilariopsis, and one species of Hydropuntia, namely, G. salicornia, G. tenuistipitata, Gracilaria sp., Gp. bailiniae and H. edulis. This is the first report of the molecular phylogeny of Gracilariaceae on Hainan Island, and it helps to clarify the taxonomy and distribution of gracilarian species in the Asia-Pacific region.

  • Two species of Leycesteria, L. gracilis (Kurz) Airy Shaw and L. formosa Wall. (Caprifoliaceae), from the Lao Cai and Yen Bai Provinces are reported here as a new generic record for the flora of Vietnam. During floristic surveys of northern Vietnam, L. gracilis and L. Formosa were encountered. A critical morphological study of all the collected specimens and the type of materials consulting the relevant literature led us to confirm the identity of our collected specimens as L. gracilis and L. formosa. The genus differs from other Vietnamese genera of Caprifoliaceae by the presence of a spike inflorescence or flowers in sessile whorls of 6. Taxonomic notes, description, and photographs are provided, together with short notes on the distribution, ecology and phenology of the two species.

  • The South Korean hermit beetle has previously been identified as Osmoderma opicum, which is distributed in Japan. Because of its rarity, this species is classified as an endangered species. To date, however, the identity of this species in South Korea has not been conclusively confirmed. To assess the taxonomic status of the hermit beetle occurring in South Korea, we performed a comparative study with the beetle's Eurasian congeners, based on morphological examination and molecular analysis using COI gene sequences. The results clearly showed that the South Korean hermit beetle is identical to Osmoderma caeleste, which has been described from the Russian Far East. Therefore, we suggest that the taxonomic identity of the South Korean hermit beetle is O. caeleste.
