Within the last 60 years the genus Valeriana L. has been repeatedly studied by different authors in Manchuria. This work was closely associated with the survey of the group in the countries surrounding Manchuria: Ussuriland, Korea and the Amur Region, since the latter survey prepared the way to a knowledge of Manchurian valerianas. The species of Valeriana in the As iatic part of Russia were examined by Ledebour, Smirnov, Kreyer, Sumnevich, Maximowicz, Komarov and Voroschilov. Manchurian members of the genus were studied by Komarov and those of Korea and Japan, for the most part, by Nakai. The results of this work were set down in several publications which are reviewed below. However, to date no systematical description, of Manchurian valerianas as a whole has been published. Therefore, it is not known exactly which members of the genus are representative for this portion of China, although they are one of the most common plants in this region. In response to the need for such an account, this preliminary revisionary study of Manchurian valerianas is offered. |
