The distribution of the woody plants of South Korea based on herbarium (SNUA) material of The Arboretum (VIII) : Daphniphyllaceae & Myricaceae

To clarify the taxonomy of Daphniphyllum (Daphniphyllaceae) and Myrica(Myricaceae), herbarium specimens collected from South Korea past forty years were examined on the basis of leaf, flower and fruit morphology. Morphological examinations showed that two taxa of Daphniphyllum could be recognized in Korea. D. macropodum is distributed from Japan, Korea to Indochina through China. D. oldhamii in China was considered to be a possible synonym of D. teijsmannii in southern islands of Korea and the coastline of Japan. The distribution of Myrica rubra was more like that of D. macropodum

A morphometric study of Berberis amurensis and B. koreana

Flower and fruit specimens with leaves of 70 specimens were sampled to investigate patterns of interspecific variation and to evaluate recognition of Berberis amurensis and B. koreana taxa using nine leaf and fruit characters. This study suggested that leaf characters (length and width) were no longer useful for identification, but leaf serration pattern and fruit shapes were useful to tell B. amurensis from B. koreana. Our data showed that B. amurensis was mainly distributed in eastern Korea (Province Gangwon-do). However, B. koreana was predominantly distributed in western area, Province Gyeonggi-do

The distribution of the woody plants of South Korea based on herbarium (SNUA) material of The Arboretum (IX) : Ulmaceae

느릅나무과는 16속, 약 2,300종이 보고되고 있으며 아열대에서 온대지역에 넓게 분포하지만 대부분 북반구에 분포한다(Willis. 1986). 본 과는 열매의 특징인 시과와 핵과로 크게 양분되는데 기존의 화분학적, 화학적, 계통학적 연구에서는 대부분 연구결과가 일치되어 두 개의 과로 양분하는 것이 적절하다는 주장이 있다(Giannasi. 1978: Oginuma et al. 1990: Grundzinskaya. 1967: Takahashi, 1989). 그러나 본 연구에서는 기존의 개념(광의)인 느릅나무과를 사용하였다. 국내 느릅나무과에 속하는 식물에는 느릅나무속(Ulmus), 시무나무속(Hemiptelea), 팽나무속(Celtis), 느티나무속(Zelkova), 푸조나무속(Aphananthe)등 5속이 보고되고 있다(Lee, 1980). 느릅나무속에 대한 분류학적 처리는 Krussmann(1986)은 5개 절(Blepharocarpus. Chaetoptelea, Micropetelea, Madocarpus, Trichoptelea)을 제시하고 있으나 최근 중국식물지(Fu. 1998)에서는 4개 절(Blepharocarpa, Chaetoptelea, Microptelea, Ulmus)로 나누고 있다. 두 분류체계에서는 별다른 큰 차이점은 없고 Madocarpus를 Ulmus로 대치한 것과 미국에 분포하는 U. serotina의 Trichoptelea가 누락된 정도다. 국내에 분포하는 수종 중 참느릅나무만이 Microptelea절에 속하고 모든 종들이 Ulmus절에 속한다. ..

The distribution of the woody plants of South Korea based on herbarium (SNUA) material of The Arboretum (IV) : Clematis (Ranunculaceae)

To clarify the taxonomy of Clematis of Ranunculaceae, herbarium specimens collected from South Korea past forty years were examined on the basis of leaf, flower and fruit morphology, The qualitative and quantitative characters showed that eleven taxa could be recognized. The current study rejected several taxa, such as C. heracleifolia var. davidiana Hemsl, C. chiisanensis Nakai, C. nobilis Nakai, C. subtriternata Nakai. On the other hand C. fusca var. coreana Nakai justified varietal status as an endemic plant to Korea. Also, a plausible suggestion was that C. ochotensis, be recognized under a variety of European taxa, i.e., C. alpina(L.) Mill. var. ochotensis (Pall.) S. Wats. Results from this current study showed that C. fusca var. coreana Nakai, C. brachyura Maxim, and C. trichotoma Nakai justified endemic plants to Korea..

The distribution of the woody plants of South Korea based on herbarium (SNUA) material of The Arboretum (VII) : Rhamnaceae

To clarify the taxonomy of Ramnaceae, herbarium specimens collected from South Korea were examined on the basis of leaf, flower, and fruit morphology. The qualitative and quantitative characters showed that 13 taxa could be recognized. The current study could not confirm the existence of Rhamnus utilis Decne., R. diamanticus Nakai, and R. parvifolius Bunge in South Korea. On the other hand, R. davuricus var. nipponicus justified a species status as R. ussuriensis J. Vass due to the presence of thorn in the winter terminal bud. Also, a plausible suggestion was that Berchemia wilsonii in central China may be recognized as a synonym of B. berchemiaefolia in Korea and Japan. Results from this current study showed that B. racemosa justified the old name of B. floribunda in China. Finally using a key and a limited sample of the Arboretum herbarium specimens (SNUA) to all taxa, the distribution maps were provided here

A study of wild germplasm collections in Korea (II) : determination of the best dates for seed collections of woody plants

The seeds of 163 taxa at from the diverse wild populations in South Korea were collected by our staffs of the Arboretum for six years (1995-2000). More than 138 taxa (ca. 85%) were collected mainly from September to October. Successful long-term survey is recommended to determine the best dates for seed collections of woody plants in Korea

Flora of Mt. Gae-myeong of Gyeonggi Province

Mt. Gae-myeong (alt. 621.8m) and adjacent regions were investigated for floristic study using the GPS. Also, our current field work was intended to inventory rare and endangered plants using thirty three meshes and six routes. From this study, 163 taxa of 61 families and 124 genera were found and collected. Major vegetation type was composed of oak community here, such as Quercus serrata-Q. dentata-Q. mongolica-Q. acutissima. Also, many planted taxa, Larix kaempferi-Pinus rigida-Pinus koraiensis were easily founded within the investigated area. Among many studies sites, three meshes, C2, E2, and F2 were found to be core area for protection

Flora of Mt. Sin-sun-bong of Gangwon Province

This study was carried out to investigate the flora of Mt. Sin-sun-bong (alt. 1,204m) and adjacent regions located on the northern side of Seol-ak National Park, in province Gangwon-do, from April to September, 2002. The purpose of our study was to enlist vascular plant species of Mt. Sin-sun-bong, Ma-san (alt. 1,252m) and 780 peak (alt. 780m) and to inventory rare and endangered plants. During the exploration, we found 62 families, 151 genera, and 231 taxa (including species, subspecies, varieties and forma). The flora of Mt. Sin-sun-bong included thirty-nine taxa as the endangered species..

Flora of Mt. Baek-deok-san

백덕산(1,350m)은 행정구역상으로 강원도 영월군 수주면 법흥리에 속하고, 지리적으로는 동경 128º 17′ 44.2″, 북위 37º 23′ 37.3″ 에 위치하며 영월군과 평창군의 경계를 이루고 인접한 치악산 국립공원과 함께 강원도의 서남단에 위치하고 있다. 인근의 신라시대에 창건된 고찰 법흥사에는 국내 5곳 뿐인 적멸보궁과 보물 제612호인 징효국사 탑비가 있어 용소폭포와 인접한 치악산 국립공원 등 자연 경관과 함께 주요 관광자원이 된다. 백덕산은 태백산맥에서 치악산을 거쳐 차령산맥으로 이어지는 백두대간의 연결부분을 구성하며, 백덕산과 사갓봉을 제외한 산지는 고도가 1,000m 미만으로, 백덕산과 함께 현재까지 식물상 및 식생에 대한 연구가 수행되지 않았다. .

Flora of Mt. Gwang-gyo-san (II)

Mt. Gwanggyo and adjacent regions were revisited to study flora based on pinpoint collection data (GPS) as well as to inventory rare and endangered plants. Thirty four meshes and seven routes were established to make a decision for the conservation priority. During the exploration, we find 46 families, 76 genera and 95 taxa (including species, subspecies, varieties, and forma). There were five prior species. Abies nephrolepis, Prunus padus, Cornus controvera, Acer pictum var. mono, and Pyrus ussuriensis, which were the 3rd level of conservation priority. According to conservation priority, five meshes. C1, E4, E5, F3, and F4 were core areas to be protected. In the course of study, we were not able to find more individuals of Corylopsis glabrescens var. gotoana except four individuals in 1992 study
