We report a new distribution of Sedum kiangnanense D. Q. Wang & Z. F. Wu on the Korean Peninsula. This species was first reported in China and is distributed in Anhui and Zhejiang provinces. We found this species on Hongdo Island in Heuksan-myeon, Shinan-gun, Jeollanam-do in the Republic of Korea. S. kiangnanense is well distinguished from other species in Korea by 4- or 5-verticillate leaves on the sterile stems and a spatulate leaf shape. We provide its morphological description, detailed illustrations, and a key to related taxa. We have given this species a new Korean name, Ip-kkot-dol-na-mul, which means flower-like leaved sedum.

Pollens of 20 species of Sedum were investigated with a scanning electron microscope. The pollen morphology of Sedum was rather variable, within particular species or even within a single inflorescence. Differences occurred in the number and shape of apertures and surface sculpture. Besides 3-colporate, various aperture types including 2-syncolporate, 3-syncolporate, 40stephanocolporate, 5-stephanocolporate, zonate, and irregular types were found in a single specimen. Also, striate-rugulose and psilate sculpture were found in S. viviparum. No correlation was found between the pollen morphology and the floral formula. Pollen characters appeared to be not useful for infrageneric classification of Korean Sedum.

The present paper deals with a research of life form and vegetation of the plants extant in the habitat of endangered Parnassius bremeri in Uiseong, Gyeongsangbuk-do with a view to restore their habitat and create substitute habitats. The research found that there are a total of 130 vascular plants including 47 families, 96 genera, 113 species, 1 subspecies and 16 varieties. In terms of their life form, hemicryptophytes (H) is the majority of dormancy form with 41 species or 31.54%, while $R_5$ is majority of radicoid form with 72 species or 55.38%, gravitational disseminule form ($D_4$) is majority among the disseminule forms with 68 species or 52.31% and erect type (e) is majority of growth form with 57 species or 43.85%. Major constituents of the habitat are Sedum kamtschaticum, Selaginella tamariscina, Orostachys japonica, Arundinella hirta, Cymbopogon tortilis var. goeringii, Themeda triandra var. japonica, Carex humilis, Indigofera kirilowii, Imperata cylindrica var. koenigii, Festuca ovina, Artemisia capillaris, etc., all of species which are in the initial stage of succession and show simultaneously features characteristic of vegetation on the rock. In the habitat 1. Sedum kamtschaticum- Selaginella tamariscina community and Pinus densiflora community are distributed whereas, in the habitat 2. Sedum kamtschaticum-Selaginella tamariscina community, Sedum kamtschaticum-Carex humilis community, Sedum kamtschaticum-Cymbopogon tortilis var. goeringii community and Sedum kamtschaticum-Imperata cylindrica var. koenigii community are growing and in the habitat 3. Sedum kamtschaticum-Selaginella tamariscina community, Selaginella tamariscina community, Sedum kamtschaticum-Indigofera kirilowii community and Quercus acutissima community are seen distributed there, too. Typical of food plants growing in the habitat is Sedum kamtschaticum, found mostly in the rocky area and its surroundings. Absorption plants are those that usually bloom in the season when imagoes emerge. From the research, it becomes evident that the blooming season of Sedum kamtschaticum, obviously a food plant, corresponds exactly to the emergence timing of imagoes. Cirsium japonicum var. ussuriense, Rosa multiflora, Erigeron annuus, Spiraea prunifolia var. simpliciflora are found to belong to these plants.

Sedum kamchaticum, Sedum middendorffianum and Sedum takesimense belong to the sebum species. Especially, Sedum takesimense is a Korean native species growing only on Ullenung-do. Few studies for the biological activities of these plants have been reported. In this study, we examined biological activity and the contents of functional components of the aerial part and the root part of Sedum kamchaticum, Sedum middendorffianum and Sedum takesimense. As the results, the roots of Sedum takesimense showed the highest total phenolic contents (TPC : $13040{\pm}50.0mg\;GAE{\cdot}100g^{-1}$), and the aerial part of Sedum takesimens showed the highest total flavonoid contents (TFC : $2722.2{\pm}107.1mg\;CAE{\cdot}100g^{-1}$). Meanwhile, Sedum middendorffianum exhibited the highest anti-oxidant activity (DPPH $RC_{50}$ value of aerial part : $50.69{\pm}0.75{\mu}g{\cdot}mL^{-1}$, DPPH $RC_{50}$ value of root part : $27.27{\pm}0.55{\mu}g{\cdot}mL^{-1}$; ABTS $RC_{50}$ value of aerial part : $11.32{\pm}0.38{\mu}g{\cdot}mL^{-1}$, ABTS $RC_{50}$ value of roots part $5.54{\pm}0.02{\mu}g{\cdot}mL^{-1}$). The root part of Sedum middendorffianum showed the potent alpha glucosidase inhibitory activity (AGI $IC_{50}$ : $60.69{\pm}0.72{\mu}g{\cdot}mL^{-1}$). In order to elucidate active principle of Sedum middendorffianum that was shown the most potent antioxidant and anti-diabetic activities, the methanol extract of Sedum middendorffianum was fractionated with various solvents according to the polarity successively. As a result, EtOAc fraction of Sedum middendorffianum showed the highest contents of functional components (TPC : $16245.8{\pm}1025.7mg\;GAE{\cdot}100g^{-1}$, TFC : $4850.4{\pm}182.9mg\;CAE{\cdot}100g^{-1}$). And it also showed excellent anti-oxidant activities (DPPH $RC_{50}$ : $14.0{\pm}0.6{\mu}g{\cdot}mL^{-1}$, ABTS $RC_{50}$ : $3.4{\pm}0.1{\mu}g{\cdot}mL^{-1}$) and anti-diabetic activity (AGI $IC_{50}$ : $79.0{\pm}2.2{\mu}g{\cdot}mL^{-1}$). Above results suggest that Sedum middendorffianum can be developed to health functional material as a plant resource with potent antioxidant activity.

한국산 돌나물과 식물 4개 속 22종 23개 표본의 화분을 광학 및 주사전자현미경으로 관찰한 결과 발아구연의 유무, 과립상 돌기의 유무는 속간의 유연 관계를, 유선상 돌기의 모양은 Sedum속내 분류군의 한계를 설정하는데 유용한 정보를 제공하였다. 한국산 돌나물과의 화분립 모양은 소립-중립이고, 세잎꿩의비름이 가장 작고 섬꿩의비름이 가장 컸으며, 화분의 극면상립은 원형이며, 적도면상은 약장구형-장구형, 발아구는 3 공구형이었다. 표면 무늬는 유선상이었고, Hylotelephium, Meterostachys, Orostachys는 발아구연과 표면에 과립상 돌기를 가진 분류군으로 기존의 분자적, 형태학적 결과와 마찬가지로 위 분류 군들이 매우 유연 관계가 깊은 군임을 지지한다. 유집분석 결과, Sedum속은 유선상 돌기 상면이 둥근 군과 평평한 군으로 나누어지고, 유선상 돌기 상면이 둥근 군 중에서 표면에 과립상 돌기를 가진 군인 섬기린초, 애기기린초와 과립상 돌기를 가지지 않은 군으로 뚜렷하게 나누어진다. 또한 Sedum속에 속하는 종들이 여러개의 유집으로 흩어져 있어 Sedum속을 세분화할 필요가 있다고 한 기존의 연구 결과와도 일치하고 있다. 종간의 유연 관계에 있어서도 Aizoon아속 내 기린초와 애기기린초는 유일하게 과립상 돌기가 표면에 존재하고 있어 이들이 매우 가까운 유연 관계임을 시사하고 있으며, Sedum아속에 포함시켰던 S. polytrichoides 가 Meterostachys, Hylotelephium, Orostachys속 종과 유집 되고 있어 본 종의 분류학적 위치가 재고되어야 할 것으로 생각된다. 정동진에서 채집된 O. malacophyllus의 경우, 현재까지 한국에 보고된 동일종의 집단과 형태적으로 차이가 있을 뿐 아니라 화분 형태적으로도 뚜렷한 차이가 있어 두 집단이 서로 다른 종일 가능성이 있다 고 판단된다.

This studies were conducted to investigate on the shade adaptation of native Sedum kamchaticum and Disporum smilacinum. All plants were grow under the controlled light intensity conditions, which controlled by two shading materials, white and/or black shading net. The results obtained were as follow. 1. Daily changes of the shading area around of the building were various by building height, width and direction. 2. Upper canopy was composed to Pinus densiflora as dominant species in native sites of Disporum species. 3. Many branches of Disporum smilacinum were sprouted after pinching. However their growth were less elongated shorter than those of Disporum viridescens. 4. Sedum sarmentosum was poor growth under the low relative light intensity as 50%, however, the growth of this species closely was similiar as under the full sun condition.

The composition of the phenolic compounds of 14 species, 2 varieties and I taxon of the Sedum plant in Korea were studied to identify their inter-specific relationships and their taxonomical position. The phenograms and contour diagrams obtained from the HPLC of EtOAc soluble fraction of these plants were classified into 7 alliances according to their chemical patterns. These chemical patterns agreed with Satake's classification except for Sedum aizoon. These plants were subdivided into 5 alliances in the Sedum section and 2 alliances in the Hylotelephium section. I type of the Sedum spectabile showed a difference in the number of stamens, it could be trated as another category above variety according to this result.
