The crude drugs, "Yuzhu (玉竹)" and "Huangjing (黄精)," have been used as different drugs in the Chinese medical system. However, the botanical origins of the two drugs are often confusing because of the morphological similarities of the rhizomes of their original plants (Polygonatum species). To avoid mis-uses their botanical origins must he clarified. Therefore, to identify the botanical origins of the contemporary "Yuzhu,""Huangjing" and related drugs available in China, Hongkong and Japan, the rhizomes of thirteen Polygonatum species from China (five species of Ser. Alternifolia, one species of Ser. Kingiana and seven species of Ser. Verticillata) were studied anatomically. The results showed that the rhizomes of each taxon can be distinguished from each other by the differences of thickness of cuticles, types, density and diameters of vascular bundles, diameters of vessels, density and diameters of mucilage cells, diameters of parenchyma cells in the steles, etc.
