  • 서양등골나물은 우리나라에서 생태계 교란 생물로 지정된 외래 침입종이다. 북아메리카 동부지역이 원산지인 이 외래 식물에 대해 각각 2개의 학명(Eupatorium rugosum Houtt., Ageratina altissima (L.) R. M. King & H. Rob.)과 국명(서양등골나물 및 미국등골나물)이 혼용되고 있어 분류학적 혼란을 초래하고 있다. 이 논문에서는 이들의 분류학적 실체와 내력을 밝혀 분류학적 혼란을 해결하고자 하였다. 조사 결과, 미국등골나물과 서양등골나물은 동일한 분류군으로서 린네가 Species Plantarum에 Ageratum altissimum으로 처음 기재한 종이다. 이 종은 Eupatorium속으로 전이되어 대체명이 공표되고 이후 Ageratina속으로 전이되었다. 즉, Eupatorium속에서는 전혀 다른 기준표본에 근거해 이미 존재하였던 E. altissimum L. 때문에 대체명으로 E. rugosum이 공표되었고, Ageratina속에서는 종소명 'altissima'를 사용하고 있던 종이 없었기 때문에 원명에 근거해 A. altissima의 학명이 공표되었다. 이러한 과정에서 발표된 이름들이 국내에서는 서로 다른 분류군으로 인식되면서 분류학적 혼란이 야기된 것으로 사료된다. 형태 및 분자 형질을 분석한 연구 결과에 근거해 서양등골나물의 정명은 A. altissima이다.

  • Taxonomic confusion has been presented within freshwater crayfishes of the genus Cambaroides since Starobogatov published morphological definition and revision of the group in 1995. He suggested that Cambaroides should be revised: the C. dauricus, contained three species C. dauricus, C. wladiwostokiensis, and C. koshewnikowi; the C. schrenckii with two. species C. schrenckii and C. sachalinensis. Also Straovogatov did not take into account the previous data. of crayfish distributions. In order to. clear up the confusion, the taxonomy of crayfish sampled from Mongolia, Russia, China, and North Korea was reassessed. Starovogatov's key could not lead to the correct identification. Also, detailed observations of apical robe of the male first pleopod did not support the taxonomy on the genus Cambaroides proposed by Starobogatov in 1995. However, some local variations of morphology exist in rostrum, pleuron, and telson of Asian crayfish. Future studies should be concentrated on whether there are geographical clines of morphology or if taxonomic subdivision is necessary.

  • 쏨뱅이아목 (Scorpaenoidei) 어류에 속하는 꼼치과 (Liparidae) 어류는 형태적으로 유사하고 오동정 가능성이 크며 체색과 몸의 상대적인 크기 변이가 심하여 분류학적으로도 상당히 혼란스러운 분류군이다. 따라서, 본 연구는 꼼치과 어류의 자원변동을 이해하고 자원관리를 위해 국내 보고된 3속 10종을 대상으로 분자계통 및 분류학적 재검토를 수행하였다. 미토콘드리아DNA COI 영역과 핵DNA RAG2 영역의 염기서열을 이용한 분자계통 분석 결과, 물미거지가 분홍꼼치와 가깝게 유집되는 mtCOI 계통 결과를 제외하면 3속 (분홍꼼치속, 물미거지속, 꼼치속)이 대등한 단계통성을 나타내었다. Gilbert and Burke (1912)는 L. ochotensis와 구분되는 한국산 미거지를 L. ingens로 신종 보고하였으나, 본 연구에서 한국산 미거지는 일본산 및 러시아산 L. ochotensis와 형태 및 분자에서 잘 일치하였으므로 한국산 미거지의 학명을 L. ingens에서 L. ochotensis로 변경한다.

  • Picea jezoensis with several infraspecific taxa is indigenous to Eastern Asia and the Far East of Russia. Although these taxa are very common, the taxonomic confusion surrounding this complex is reflected in ambiguity of the various taxonomic treatments currently used. Patterns of intraspecific variations of cone morphology and recognition of taxa within the P. jezoensis complex were investigated from 175 individuals. Morphological variation of cone characters was determined by the univariate analysis to be insignificant in separating most previously recognized infraspecific taxa in Korea, China, Russia, and Japan. Our statistical analysis showed that cones from northern populations were larger and wider than those from southern populations. Individuals from South Korea were predominantly smaller even than those from Honshu of Japan which were previously recognized as var. hondoensis. All measured characters appeared to show some clinal variation with changes in latitude, and a distinctive trend was evident. Consequently var. hondoensis, var. koreana, and var. microsperma cannot retain their infraspecific state within the P. jezoensis complex.

  • This study was attempted to clarify the taxonomic problems that have been raised up to now in the study o section Telephium, genus, Sedum: the delimitation of taxa belong to Telephium group, their relationship, and nomenclatural confusion and the rank of Telephium group. Specimens were collected at 19 sites in Korea. The habitat, distribution, external morphological characters of habit, leaf shape, phyllotaxy, inflorescence, color of floral organs, floral formula, carpel, capsule, and micro-characters of pollen, seed coat, stigma and anther with SEM were examined. Through this study, the following results were obtained. The delimitation of taxa that belong to section Telephium in Korea and their relationship Nomenclatural errors were corrected. In S. rotundifolium Lee, species epithet“rotundifolium”is later homonym of s. rothundifolium Lamarck, so corrected to S. duckbongii Chung and Kim by article 64 of ICBN. Phyllotaxy was elucidated to meaningless, character in sect. Telephium. S. taquetii was a separate species from S. viridescens and not of its synonym. S. alboroseum Baker in Korea was S. erythrostictum sensu Master not of S. erythrostictum Miquel. By this study , taxa of sect. Telephium in Korea were arranged to 7 species. Considering interspecific relationship of sect. Telephium, S. duckbongii and S. alboroseum are considered to be more advanced forms and S. viridescens, S. taquetii, and S. viviparum to be more primitive forms among 7 species.

  • Anatomical comparison of 3 North American species with commercial name of redcedar was executed to provide taxonomic information for prevention of confusion and establishment of sound business transaction in the wood market. Eastern redcedar (Juniperus virginiana) and southern redcedar (Juniperus silicicola) could not be separated on the basis of microstructure and ultrastructure of wood. Western redcedar (Thuja plicata), however, appeared to be obviously separated from eastern and southern redcedar in a number of microscopic and ultramicroscopic features. Useful features for separating these two groups were intercellular spaces in transverse surface, latewood width, radial intertracheid pitting, warty layer and pits with torus extensions in tracheids, ray composition, nodular end walls in ray parenchyma cells, and cross-field pitting.

  • Disagreement among the various publications providing lists of Korean endemic plants makes confusion inevitable. We summarized the six previous reports providing comprehensive lists of endemic plants in Korea: 407 taxa in Lee (1982), 570 taxa in Paik (1994), 759 taxa in Kim (2004), 328 taxa in Korea National Arboretum (2005), 515 taxa in the Ministry of Environment (2005) and 289 taxa in Flora of Korea Editorial Committee (2007). The total number of endemic plants described in the previous reports was 970 taxa, including 89 families, 302 genera, 496 species, 3 subspecies, 218 varieties, and 253 formae. Endemic plants listed four times or more were collected to compare the data in terms of scientific names and synonyms (339 taxa in 59 families and 155 genera). If the varieties and formae were excluded, the resulting number of endemic plants was 252 taxa for the 339 purported taxa analyzed. Seven of the 155 genera analyzed were Korean endemic genera. Among the 339 taxa, the same scientific names were used in the original publications for 256 taxa (76%), while different scientific names were used for 83 taxa (24%). The four largest families were Compositae (42 taxa, 12.4%), Ranunculaceae (19 taxa, 5.6%), Rosaceae (19 taxa, 5.6%), and Scrophulariaceae (19 taxa, 5.6%). Saussurea (Compositae) had the highest number of taxa within one genus (17 taxa; 5% of total endemic taxa).

  • Objectives : A precise and simple system of nomenclature was required to avoid error, ambiguity or confusion. Although medicinal plants must be produced or distributed based on a pharmacopoeia described origin including scientific name, the Korean Pharmacopoeia tenth edition (KP 10) had many names against the nomenclature. Therefore, this study aimed at searching correct scientific names for 241 plants in KP 10. Methods : Authoritative databases - The Plant List, International Plant Name Index, YList, Tropicos, eFloras, World Checklist of Selected Plant Families, The Global Compositae Checklist, The International Legume Database and Information Service, et al. - and previously performed researches, floras were cross-checked. Results : The arrangement of this list was designed for four cases, errors including illegitimate, nomenclatural synonyms, recommended names and decision reserved names. Consideration about the scientific names produced nine correct names for ten misspellings and illegitimate, and thirty-six correct names for forty-one nomenclatural synonyms. These results should be reflected in the next of KP 10. Separately, ten recommended names were also suggested for taxonomic synonyms which had been used indiscriminately due to diverse taxonomic opinions. In addition to those, decision reserved names were suggested for thirteen species which had been corridor of uncertainty. Then again, there was need to study about authorship, because KP 10 did not keep recommendations for author citations. Conclusions : Correction of scientific names for some medicinal plants which violated the International Code of Nomenclature would be useful to improve the accuracy of a Pharmacopoeia as the criterional materials.
