Marine benthic flora of the Izu Peninsula has been studied by ENDO (1935), SEGAWA (1935,1936,1938,1941) and CHIHARA (1967). From the results of the present study and the data available at the present time, it is known that there are 413 species of marine algae occurring in this area. Of these algae, 63 species belong to the Chlorophyceae, 80 species to the Phaeophyceae and 270 species to the Rhodophyceae. For the purpose of understanding the characteristics of the marine flora of the Izu Peninsula, it is compared with the floras of some other regions along the Pacific coast of Japan, by using various indexes, such as C/P ration, I/H ration, the number of species of the genus Sargassum and the subfamily Ecklonioideae, and the number of common species examined for the benthic species of the Chlorophyceae and Phaeophyceae. As a result, it is considered that the Izu Peninsula has a marine flora represented by warm temperate elements, having much similarities to the warmer regions, such as the Boso Peninsula and the Kii Peninsula.
