The objective of the study was to investigate vascular plants of Mueuido in Incheon from April to October, 2011. The investigation was carried out for mountains (Mt. Horyonggok and Mt. Guksa), coastal areas and annexed islands (Silmido and Somueuido). Vascular plants were found to have 338 taxa, including 90 families, 235 genera, 297 species, 5 subspecies, 32 varieties and 4 forms. Rare and endangered plants designated by Korea Forest Service had 5 taxa including Utricularia bifida, U. vulgaris var. japonica, U. racemosa, Ottelia alismoides, and Arisaema heterophyllum. The floristic regional indicator plants found in this area had 3 taxa of grade V and 5 taxa of grade III. Naturalized plants consisted of 20 taxa that made up 8.3% of the total vascular plants in this area.

본 연구는 전라남도 여수시 돌산읍에 위치하는 돌산도의 관속식물상을 조사하고 분포가 확인된 주요 식물에 대해 논의하였다. 현지조사는 2017년부터 2018년까지 총 15회에 걸쳐 수행되었으며, 이에 대한 증거표본은 국립수목원 산림생물표본관(KH)에 소장하였다. 분포가 확인된 관속식물은 113과 338속 517종 1아종 49변종 3품종 총 570분류군이다. 이중 한국특산식물은 개족도리풀 등 18분류군을 확인되었으며, 환경부지정 식물구계학적특정식물종은 V-I등급으로 총 90분류군이 조사되었다. 희귀식물은 위기종(EN)인 백양꽃 1분류군을 포함하여 총 4분류군이며, 적색목록에 속하는 관속식물은 취약종(VU) 갯취 등 총 8분류군이다.

Adenostemma madurense DC. (Asteraceae, Adenostemma L.), which is known to be distributed in Japan, Taiwan, Thailand and Nepal was recently found on Jeju Island in Korea. It is morphologically allied to A. madurense but distinguished from A. lavenia (L.) Kuntze by having such characters as broadly ovate or ovate to oblong leaves, 15-21 ㎝ long × 7-12 ㎝ wide and smooth achenes with slightly muricate at the upper. Furthermore, A. madurense is found in dry mountain slopes in evergreen forests while Adenostemma lavenia occures in the wetland and side of pond. This taxon was named ‘San-mul-meo-wi’ in Korean based on its habitat. We provide a description, illustrations, photographs, and the key to the related species in Korea.

This study was carried out to investigate the vascular plants of Mt. Nochu (1,322m) from April, 2014 to October, 2015. The vascular plants were summarized as 515 taxa, including 89 families, 304 genera, 448 species, 4 subspecies, 57 varieties and 6 forms. Among the investigated 515 taxa, 11 Korean endemic plants and 14 rare and endangered plants were included. The floristic regional indicator plants found in this area were 11 taxa of grade IV, 30 taxa of grade III. Naturalized plants consisted of 24 taxa that made up 4.6% of the total vascular plants in this area. Medicinal plants of the Korean Pharmacopoeia and Korean Herbal Pharmacopoeia distributed in this area consisted of 67 taxa.

We performed the floristic study of Carpathian mountains in Ukraine from April 2008 till October 2009. We designated eight important areas to investigate in Ukraine Carpathians including Svydovets, Chornohora, Kuziy-Trybushany, Maramorosh, Uholka-Shyrokyi Luh, Narcissi Valley, Chorna Hora, and Yulivska Hora. The total numbers of vascular plants in investigated area were 1,349 speices from 502 genera and 112 families. The endemic species to Carpathians numbered to 65 from 49 genera belonging to 24 families, and it was corresponded to 4.8% of the 1,349 vascular species. We prepared the list of vascular plants with compiling database on useful plants. Ukraine Carpathians endemic species could be applied as high value products in research and practice. Moreover, the flora of Carpathian mountains which is distributed in five nations in eastern Europe and famous for Primeval Beech Forests (Fagus sylvatica), is useful to compare the floristic study with Korean flora.
