The foliar crude drug so called "Urajirogashi" has been used in Tokushima Pref. as the folk remedy for nephrolithiasis, cholelithiasis and urethral calculi. The effect to dissolve each calculus has been proved pharmacologically and clinically, and the crude drug and their preparations are generally on the present market. The original plant of "Urajirogashi" was considered to be Quercus salicina BLUME. The results of the anatomical studies, however, confirmed that the original plants are Q. myrsinaefolia BLUME and the mixture of both species of Q. salicina and Q. myrsinaefolia besides Q. salicina BLUME. The points to discriminate each species are as follows: A) Q. salicina: Upper epidermis is 1.5〜3 times as thick as lower epidermis, and no idioblast in the part of mesophyll. Palisade ratio is 2.3〜3.7〜5.8. B) Q. myrsinaefolia: Upper epidermis is 3〜5 times as thick as lower epidermis, and idioblast are observed in the part of mesophyll. Palisade ratio is 3.5〜6.7〜10. 5. Further, the key for identification on the anatomical characteres of the leaves from Q. salicina, Q. myrsinaefolia, Q. glauca, Q. acuta, Q. hondae, Q. sessilifolia, Q. gilva, Q. phillyraeoides, Q. mongolia var. grosseserrata, Q. serrata, Q. aliena, Q. dentata, Q. variabilis and Q. acutissima was indicated as Table 4.
