This study was carried out for comparative anatomical studies on the seeds of Japanese Plantago spp. and for the identification of the original plants of seeds of various commercial Plantago samples. Among the Plantago spp. growing in Japan, four native species (P. asiatica, P. japonica, P. camtschatica, P. hakusanensis) and two naturalized species (P. lanceolata, P. virginica) were chosen as sample plants. Seed of P. japonica was the smallest in size and that of P. lanceolata the largest. The shape of seed of those native species is either polygonal or elliptical, and biconvex or piano-convex. Seeds of the two naturalized ones are typically of concavo-convex boat-shape. Hilum is in the center on the ventral side, and chalaza situated on the major axes, slightly apart from the hilum. Embryo is of straight-shape. Cotyledon is situated near to the hilum, and radicle is adjacent to the chalaza. Studies on the morphological characteristics provided means for the identification of these Plantago species. By this means, commercial Plantago seeds, said to be those of Plantaginis Herba was identified as the seeds of P. asiatica.
