  • 백두산에서 개별꽃속의 신종인 애기개별꽃(Pseudostellaria baekdusanensis M. Kim)을 새로이 발견하여 기재하였다. 애기개별꽃은 잎의 크기가 비슷하며 꽃은 줄기 끝에 액생 또는 정생하고 꽃잎은 요두인 특징을 가져 긴개별꽃(P. japonica (Korshinsky) Pax)과 유사하다. 그러나 애기개별꽃은 식물체가 9-13 cm로 소형이고 1줄의 털이 줄기에 있고 엽신 가장자리 기부에만 긴 털이 있으며 꽃잎은 깊은 요두형이고 화주는 2개이며 폐쇄화가 식물체에 달리지 않는다. 반면에 긴개별꽃은 식물체는 25-35 cm로 대형이고 1-2줄의 털이 줄기에 있고 엽신 가장자리와 이면 중륵에 긴 털이 밀생하며 꽃잎은 얕은 요두형이고 화주는 (2) 3개이며 폐쇄화가 엽액에 달린다는 점에서 뚜렷하게 차이를 보인다.

  • Yongneup wetland protected area, the only high moor in Korea, is a core area to conserve biodiversity. Even though the Yongneup wetland protected area is relatively small, various plant species are distributed in the Yongneup wetland protected area because it includes various habitats showing different environmental gradients. Vascular plants distributed in the Yongneup wetland protected area were identified as a total of 376 taxa that is composed of 73 families, 217 genera, 322 species, 3 subspecies, 44 varieties and 7 forms. For endangered plants designated by the Ministry of Environment, 5 species including Trientalis europaea var. arctica, Lilium dauricum, Halenia corniculata, Lychnis wilfordii and Menyanthes trifoliata were found and 34 taxa were confirmed to be distributed only in the mountainous wetland habitats. Regarding naturalized plants, a total of 11 taxa were distributed, but most of them were distributed in the areas where artificial interference has occurred. And in areas inside the wetlands that are relatively well preserved, 2 species of Bidens frondosa and Erigeron annuus were observed. In this study, the occurrence and distribution of Pseudostellaria baekdusanensis M. Kim, which was recently found in Mt. Baekdu and reported as a new species, were identified in the Yongneup wetland protected area. A wetland is a very vulnerable area to drastic environmental changes and damages to its ecosystem could cause the extinction of rare plant species which are distributed only in the wetlands. Therefore, it is mandatory that current status of the Yongneup wetland protected area is evaluated and actions to prevent rapid environmental changes are taken. Fourteen separate investigations were conducted in 2013 and another four in 2014, to evaluate current status of the Yongneup wetland protected area. These investigations have provided us the basic information for future actions of conservation and restoration.
