Aconites distribute widely in northern hemispere of the earth reaching to arctic zone from warm and temperate one. Hitherto, these tuberous roots, 'Cho O', have been known to be famous plant poisons and essential important drugs possessing many remedial effects in each region of the world, especially in Korea and China. In Korea, although these plants grow widely in whole districts, their classifications are quite obscure. Especially, Aconitum triphyllum $N_{AKAI}$ is distributed whole districts. To clarify the botanical origin of 'Cho O', we studied on the anatomical characteristics of Aconitum triphyllum $N_{AKAI}$ growing wild in Korea. As a result, the environmental varieties of A. triphyllum $N_{AKAI}$ were recognized.
