Samples of the surface sediments from 38 stations in the Harima Nada, Seto Inland Sea were studied palynologically.Among the 38 stations, the arboreal pollen was always observed with high frequency, especially Pinus was the highest and the herbaceous pollen and the fern spore were lower. To compare the compositions of total pollen grains and spores in the surfae csediments from the 38 stations with the actual vegetation in the surrounding area of the Harima Nada, Rrel-values were calculated as the ratios of the percentages of compositions of pollen grains and spores to the land use percentages. It was characteristic that the Rrel-value of Pinus was greater than 1 and that the value of Fagaceae was observed to be very low.The composition and number of pollen grains and spores varied with each sampling station. The distribution pattern seemed to be also determined by the supply routes, the movement of sea water and the inherent buoyancies.
