"Yinyanghuo (淫羊〓)," a well known Chinese crude drug used as a tonic, is derived from the aerial parts of Epimedium plants of the family Berberidaceae. This genus contains 20 species and 3 varieties in China, of which 13 species grow wild in Sichuan prov. As their morphological features resemble each other, the botanical sources of "Yinyanghuo" samples available in Sichuan markets do not seem to be one. In order to identify the origins of the 59 samples of this drug collected mainly in Sichuan prov. and also in other provinces of China, Hongkong, North Korea and Japan, comparative anatomical studies were carried out on the aerial parts of 13 species of this genus. The results showed that 7 of the 13 species had papilla on the abaxial epidermis of leaves whereas 6 had not. Each of the 13 species could be distinguished from each other by the characteristics such as the stomatal indices in abaxial epidermis, numbers of vascular bundles in midrib, shapes of leaf margin in transection, shapes of hypodermal cells, numbers of sclereids layers in cortex, types of hairs, etc. In this paper, anatomical characteristics of the 7 of the 13 species possessing papilla on leaf epidermis were described. The original plants of 30 of the 59 samples tested were determined to be derived from these species.
