To obtain a knowledge of the marine flora and the communities along the coast of Hidaka, Hokkaido, intertidal collections of marine plants were made at 8 points in this region in July, 1970 and May, 1971. As a result of the present survey, it is encountered that there are 134 species of marine algae and 2 species of marine grasses. Of these algae, 85 are species belonging to the Rhodophyceae, 33 to the Phaeophyceae, and the rest to the Chlorophyceae. From the viewpoint of the geographical distribution, this area has a marine flora represented by subarctic elements, in co-existence with a few number of temperate species, such as Gelidium amansii, Grateloupia filicina, G. turuturu, Caulacanthus okamurai, Gymnogongrus flabelliformis, Campylaephora crassa, Acrosorium yendoi, Undaria pinnatifida, Bryopsis plumosa and Codium fragile. The vertical distribution of marine plants in the intertidal region in this coast occurs in zones as follows, in descending order : Gloiopeltis furcata, Porphyra spp.-Pelvetia wrightii, Fucus evanescens-Analipus japonicus-Chondrus yendoi-Phyllospadix iwatensis-Laminaria angustata.
