Abstract
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.
