Comparative anatomical studies were made on the seeds of 12 Chinese Plantago spp. to identify the original plants of Chinese commercial Plantago seeds which are used in 9 provinces. On the basis of outer morphologies, microscopic characteristics and SEM observation. The key for identification was established. The seed shapes of these 12 species were classified into two types, a bi-convex or plano-convex type and a concavo-convex boat-shape type. Seven species belong to the former type and are distinguished from each other by the size and nature of pigment layer cells. Five species belong to the latter type and are distinguished by the outer shape, arrangement of cotyledon and characters observed by SEM. Of the commercial Plantago seeds collected in these nine provinces of China, the samples from four provinces were identified as P. asiatica, those from two provinces as P. major, and those from the remaining three provinces as mixtures of these two species.
