During the previous study on the crude drug "Xuory," an ethnomedicine used by "Yi (彝)" tribe in southwest China, some samples were found to be derived from plants of neither the section Hemerocallis nor the section Capitatae. "Xuancao (萱草)" available in Chinese market was also found to be derived from plants not of the above sections. In this paper, in order to identify the botanical origins of these crude drug samples, a comparative anatomical study was carried out on the roots of 6 species and 5 varieties of the section Fulvae of the genus Hemerocallis. These 11 taxa could be distinguished from each other by the following characteristics of roots: in the columnar part, the diameter of root, the diameter of cortical parenchyma cells, the density of mucilage cells, lignification of endodermal cells, the presence of thick-walled parenchyma cells in xylem and of isolated vessel members in pith; moreover, in the swollen part, the thickening of endodermal cells. According to the present criteria, 2 samples of "Xuory" obtained from native doctors of Yi tribe's areas of Sichuan and Yunnan provinces were determined to be the underground parts, mainly roots, of H. plicata, and the origins of 3 commercial samples of "Xuancao" from Guizhou and Sichuan markets were identified as H. fulva var. fulva.
