Numerous warm region plant species in Japan are found on the coast of Ise Bay. The writer investigated the distribution of these species in this area. While Lathyrus japonicus, Calystegia soldanella, Ischaemum anthephroides var. eriostachyum and Pittosporum tobira, etc. occur through the whole area of the coasts, Crinum asiaticum var. japonicum, Canavalia lineata, Euphorbia jolkini and E. esula are confined to the mouth of the bay. Such species as Dianthus japonicum, Crepidiastrum Keiskeawa, Arundo donax, Cirsium maritimum, Stephania japonica, Tetragonia expansa, Lysimachia mauritiana, Piper kadsura, Salsola komarovi, Vitex rotundifolia, Wadelia prostrata and Eurya emarginata, etc. are found far north along the eastern coast of the bay, but are present occasionally on the western coast, resulting in a peculiar distribution of the warm region plant species around the bay of Ise. The writer considered that the temperature is an important habitat factor, but the ocean current in the bay is more significant for the distribution of these species.
