우리나라 미기록 귀화식물 2종을 발견하였다. 사향엉겅퀴로 이름 붙인 Carduus natans (국화과)는 경기도 양평군 양수리 및 남양주군 진접읍에서 확인되었으며, 동속 귀화식물인 지느러미엉겅퀴(C. crispus)와 비교하여 두화는 지름이 30-60mm로 보다 크고 대게 하나씩 달리며 고개가 아래로 처지고, 총포편은 창끝모양으로 기부 바로 위가 좁아지는 특징으로 구별된다. 또한 큰키다닥냉이로 이름 붙인 Cepidium latifolium (십자화과)는 키가 1m정도로 크며 잎의 기부가 줄기를 감싸지 않고 하부 줄기의 잎이 우상으로 갈라지며 꽃차례가 짧은 산방상인 특징으로 유사종과 식별된다. 서울 난지도 월드컵 공원에서 처음 확인되었으며 수 백 개체 정도가 발견되어 확산추세에 있는 것으로 판단된다.

Shoot weight of Orostachys japonicus should determine its profitability. The study was done to determine the effect of phosphorus and potassium fertilization (0, 5, 10, 20 kg $P_2O_5$ or $K_2O$ /1000 $m^2$) on its growth, morphological characters, and flowering. Night-break treatment of 2 hours at midnight were done since Aug. 25 when afterward samples were taken every 4 weeks to Nov. 16. Growth, morphological and flowering related characters were measured from each sample. Plant height, inflorescence length, number of leaves including bracts and stem diameter were increased with increased P and K levels. Leaf and bract, floret, shoot and total dry weights showed similar response to the above morphological characters although P fertilization more increased them than K fertilization. Florets were more formed with increased P and K levels but were not flowered due to the night-break treatment, meaning that P and K fertilization had little effect on anthesis of the florets formed.

This study aimed to characterize the morphological variations in the vegetative and floral traits of 73 wild Lilium amabile plants from six habitats in Korea. It was observed that L. amabile is distributed nationwide at any altitude from 300 m (Mt Mangdaeam) to 1550 m (Mt Halla). The majority of the natural habitats of L. amabile were found on mountain slopes, and some were found in rugged mountain regions. The down-facing flowers of this species not only had many blotches but also dense trichomes, and the flowering time was found to be from mid-June to mid-July. ANOVA revealed significant variations in vegetative and floral traits among the six habitats, indicating that the environment has substantial influences on the various growth parameters of L. amabile, such as plant height; number of leaves, bracts, papillae, and flowers; leaf angle; and lengths of the anther, longest blotch, and nectary of the petiole. In addition, the vegetative and floral traits were found closely correlated with each other under the direct impact of the environment. These findings will facilitate to find the appropriate environmental conditions for the conservation and development of L. amabile population as future lily-breeding materials.

Invasive alien species management is pivotal for biodiversity conservation. Commelina caroliniana Walter, from the family Commelinaceae, is an alien plant native to the Himalayas and India, but it has been widely introduced around the world, including in the United States, Brazil, Philippines, and Japan. In Korea, the first population was found growing adjacent to agricultural land and farm roads on Jejudo Island, and field observations confirmed the presence of at least nine populations there. It is similar morphologically to C. diffusa Burm. f. but can be distinguished by involucral bracts that are ciliate at the base, hairs on the peduncle and obsolete upper cincinnus, brown spots on its 4-lobed antherode, and seed surfaces that are smooth to slightly alveolate. It was determined to have an invasiveness low score of 8 according to the Korean 'Invasive Alien Plant Risk Assessment', suggesting that it may spread to natural habitats. Although the current distribution of C. caroliniana is restricted to Jeju-si, it has spread dramatically in many other areas of the world. At present, it has had a limited impact on the local environment, but local and regulatory authorities should pay close attention to this plant and take measures to prevent its expansion in the future.

Daphne kiusiana is an evergreen shrub with dense head-like umbels of white flowers distributed in southern Korea, Japan, China, and Taiwan. Plants in China and Taiwan are recognized as var. atrocaulis by having a dark purple stem, elliptic leaves, and persistent bracts. Recently, plants on Jejudo Island were segregated as a separate species, D. jejudoensis, given their elliptic leaves with an acuminate apex, a long hypanthium and sepals, and a glabrous hypanthium. Morphological variations of three closely related taxa, the D. kiusiana complex, were investigated across the distributional range to clarify the taxonomic delimitation of members of the complex. Twelve characters of the leaf and flower were measured from digitized herbarium specimens using the image analysis program ImageJ and were included in a morphometric analysis, the results of which indicate that the level of variation in the characters is very high. The results of a principal component analysis weakly separated D. jejudoensis from D. kiusiana according to their floral characteristics, such as a longer, glabrous hypanthium, and larger sepals. However, some individuals of D. kiusiana, particularly those from Bigeumdo Island, were included in D. jejudoensis. Recognition of D. kiusiana var. atrocaulis based on the leaf shape was not supported in the analysis, and D. jejudoensis may be recognized as a variety of D. kiusiana. Our morphometric analysis shows that digitized images of herbarium specimens could be useful and an additional method by which to investigate more diverse specimens.

Objectives : Paemo is a phlegm-resolving drug with cold properties and classified 5 kinds which come from 11 species of original plant. All the more, according to literature record, 20 species of original plant were used. As a natural result, these are easily to confuse and there are a lot of counterfeit product. So we are to present a differential standard of Paemo. Methods : It was planed a differential standard form through outer appearance of the original plant and outer appearance in the form of each medicines which was collected local market or field for 11 species which is listed in Korea or China pharmacopeia. Results : It was possible to distinguish the orignal plant between Fritillaria and Bolbostemma through its stem shape. In Fritillaria of original plant, it was possible to distinguish through its width of leaf, number of leafy bracts, color and position of flower and shape of leaf apex. In outer appearance in the form of each medicines, there are difference in color and texture of medicine between Fritillaria and Bolbostemma and there are difference in size, shape, size of inner and outter fleshy leaf of bulb, pattern of surface and apex of fleshy leaf of bulb among 10 Fritillaria species. Conclusions : This study presents various differences in the outer appearance of the original plant and the outer appearance in the form of each medicines among Paemo. It will be helpful to further applied research.

금강초롱꽃 자생지 6지역(오대산, 향로봉, 대암산, 화악산, 점봉산, 설악산)에 대한 형태적 유연관계를 알아보기 위하여 외부형태, 주성분분석과 유집분석 등 수리분류학적 연구를 실시하였다. 연구 결과, 외부형태형질 중 자생지간에 뚜렷한 차이를 보이는 형질은 없었으며 형질의 연속성이 인정되었다. 조사된 6개 자생지의 71개체와 outgroup으로 사용한 검산초롱꽃 7개체, 총78개체 중 향로봉과 설악산 정상부에서 자라는 일부 개체들은 잎, 포엽의 형태 등 에서 다소 차이를 보여 구별이 가능하였다. Outgroup으로 사용된 검산초롱꽃은 꽃받침의 형태가 넓은 난형 으로 선형 또는 선상피침형인 금강초롱꽃과 구별되었으며 나머지 형질들은 비슷한 경향을 보였다. 17가지의 양적 형질을 이용한 주성분분석 결과 주성분1(22.3%), 주성분2(15.7%), 주성분3(12.0%)이 총 50.07%의 기여율을 보였으며, 주성분 1과 2를 이차원공간에 도시한 결과 6개 자생지 집단은 서로 중복되어 나타나 구별이 불가능하였다. 평균연결방법과 Ward's법 에 의한 유집분석 결과도 주성분분석과 매우 유사한 결과를 보여 유집이 불가능하였다.

피나무속 식물은 화경의 아래에 부착된 선형의 포를 특징적으로 가지고 있으며 이러한 형질은 아욱과의 다른 속과 구분된다. 본 연구는 피나무속의 종간 계통학적 유연관계를 규명하고자 하였다. 계통학적 분석은 한국과 일본의 피나무속 10종, outgroup으로 멕시코목화를 선정하여 수행하였다. nrDNA의 ITS와 cpDNA의 trnL-F, rpl32-trnL의 염기서열을 확보하여 분석하였다. ITS, trnL-F 와 rpl32-trnL의 data를 유합한 결과 계통수는 6개의 분계조로 구성되었다. 구주피나무는 outgroup과 가장 가깝게 나타났다. 피나무 , 뽕잎피나무 그리고 털피나무는 한 분계조를 형성하였다. 연밥피나무, 섬피나무, 일본피나무는 각각 독립적인 분계조를 형성하였다. 섬피나무는 일본피나무와 가장 가까운 관계를 보여주었다. 보리자나무, 찰피나무, 염주나무는 하나의 분계조를 형성하여 서로 근연관계에 있음을 보여주었다.
