本文对败酱科败酱属的八种植物进行了生药形态组织的比较研究和描述,讨论了几种败酱根茎中周皮的发生部位以及木质部中薄壁组织环带的发生与发展,并指出北京延庆县采到的双蕊败酱与从其模式标本产地辽宁老铁山采得的标本虽然形态上相同,但组织构造上有显著差异。 In this paper, the comparative study and description of the morphogenetic organization of the eight species of the genus Patrinia in the genus Paeniaceae were discussed. The occurrence and development of the peristalsis in the roots of several decomposed sauces and the occurrence and development of parenchyma in the xylem were discussed. It is pointed out that although the morphology of the samples collected from Yanqing County, Beijing, and the old Tieshan Mountain, Liaoning Province, which is the origin of the model specimen, are the same, there are significant differences in the tissue structure.
