The species of the genus Clematis of Ranunculaceae have been known to the world not only as poisonous but also as medicinal plants from antiquity. A series of pharmacognostical studies on the medicinal Clematis plants will be presented in turn. In the case of Chinese crude drug, "Weilingxian" (威霊仙) in Chinese is derived from the underground part of Clematis plant, of which botanical origin is rather complicated. To clarify the botanical origin of this "Weilingxian," anatomical fundamental characteristics of the roots of Clematis terniflora DC. var. robusta (CARR.) Tamura, as a representative of Clematis plants, were studied in this paper. Moreover, comparing with three Clematis species from Japan, the botanical origin of "Weilingxian" from Japan, "Ireisen" in Japanese, was examined anatomically. Our results showed that the anatomical characteristics of the roots of Clematis plants vary significantly according as the roots and stocks grow, and "Ireisen" was derived from under- ground part with short stems of Clematis terniflora var. robusta.
