Electron microscopic studies on the pollen grains of some plant species of genus Plantago and commercially available folk medicine called "Shazenso" and "Shazenyomatsu" were made. The following results were obtained. In order to identify the original plant of "Shazenso" and "Shazenyomatsu" in market, the pollen grains collected from six species of genus Plantago were subjected to electron microscopic examination. It was found easy to distinguish each of the species belonging to genus Plantago according to the observations of the exterior configuration of their pollen grains with electron microscope. The configuration of the pollen grains from "Shazenso" and "Shazenyomatsu" were the same as those of P. asiatica. The above facts showed that "Shazenso" was identical with P. asiatica and also that a great deal of pollen grains of P. asiatica were contained in "Shazenyomatsu". All the pollen grains of these species of genus Plantago were shown to have operculum, although slight difference in ornamentation on operculum may exist. The pattern of the pollen grains of genus Plantago was found to comprise tuberculata-spinoid. Many canals were seen on the surfaces.
