초록

한국의 십자화과 꽃다지속 식물 우수리꽃다지 (Draba ussuriensis Pohle)를 백두산에서 새로이 발견하여 보고한다. 본종의 특징은 꽃이 흰색이고 다년생인 점이 구름꽃다지(Draba mongolica Turczaninow)와 유사하지만, 줄기와 과경에 털이 없고 경엽의 수가 작은 점이 구름꽃다지와 다르다. 국명은 학명의 종소명에서 유래한 이름을 사용하였다. 또한 과거 백두산 및 관모봉 지역에서 자라는 구름꽃다지는 D. incana L., D. glabella Pursh, D. nipponica Makino, D. daurica DC. 등으로 혼돈하여 알려졌다. 그러나 백두산 및 관모봉에서 채집한 표본들을 조사하고 유연종들과 비교분석한 결과 D. mogolica로 밝혀져 그간 잘못 사용된 학명을 바로 잡았다. 따라서 한국산 꽃다지속 식물은 흰꽃 피는 두 종과, 노란색 꽃이 피는 꽃다지를 포함하여 총 3종이 분포한다.

Draba ussuriensis Pohle is reported from Mt. Baekdu in this paper as a new member of Korean flora. D. ussuriensis is a white-flowered perennial herb and similar to Draba mongolica Turczaninow. However, D. ussuriensis differs from Draba mongolica Turczaninow in a number of characters. The stems and pedicels of D. mongolica are covered by dense trichomes, while those of D. ussuriensis are glabrous or glabrescent. D. ussuriensis has fewer cauline leaves compared to D. mongolica. The Korean name of D. ussuriensis Pohle stems from the specific epithet of its scientific name. In addition, D. mongolica is a new name, replacing the previously misidentified names of D. glabella Pursh, D. daurica DC., D. incana L., and D. nipponica Makino in several different studies. We corrected the name based on a comparative morphological study of specimens collected from Mt. Baekdu and Gwanmobong and related species. As a result, Korean Draba consists of three species: two white-flowered species and one yellow-flowered D. nemorosa L.
