Excluding species of the subfamily Bambusoideae which are all C_3 species, identification of C_3 and C_4 species of the grass family in Japan was carried out, then geographical distribution of C_3 and C_4 species in Japan with special reference to climatic conditions was investigated. Obtained results are as follows : 1) Since the CO_2 compensation point is closely related to the "Leaf Anatomy" and no exceptional relationships were observed in this study. Tested species were accepted as C_3 or C_4, depending on the tested results, regardless of whether the distinction was made on the basis of CO_2 compensation point, "Leaf Anatomy". We also classified untested species as C_3 or C_4, where possible, on the basis of their taxonomic affinities. 2) The species belonging to the subfamily Oryzoideae, Arundinoideae, Festucoideae are all C_3 species, and to the Eragrostodeae are all C_4 species. Most of the species belonging to the subfamily Panicoideae are C_4 species, but it is noted that the exceptional C_3 species are also contained in the genus Isachne and Coelachne of the tribe Isachneae, the genus Panicum, Sacciolepis and Opismenus of the tribe Paniceae. 3) High correlations exists between geographical distribution of percent C_4 expressed as percentage of C_4 species in the total grass flora and climatic conditions, especially yearly mean temperature conditions. 4) Increase in percent C_4 of the grass family with latitudinal descend in Japan depends chiefly on increase in species of the subfamily Panicoideae and decrease in species of the subfamily Festucoideae. On the other hand, no remarkable changes in species of the subfamily Oryzoideae, Arundinodeae and Eragrostoideae were found. 5) In the subfamily Festucodeae, it was found that perennial species increased and annual species decreased with latitudinal ascend, at the same time, in the subfamily Panicodeae, perennial species decreased and annual species increased with latitudinal ascend. It is most likely that the life-form of plant is related to the ecological distribution of the grass family.
