• A freshwater algal flora of East Ongul Island is described. Nine water samples and 9 algal mat samples were collected from various inland waters in the summer of 1983-1984. A total 14 species were found in the water samples: Cyanophyceae, 7 species; Chrysophyceae, 1 species; Bacillariophyceae, 4 species and Chlorophyceae, 2 species. Paraphysomonas vestita (STOKES) DE SAEDELEER of the Chrysophyceae was found for the first time in Antarctica. This alga was dominant in a lake (L. Midori) in the summer of 1983 and amounted to 20 cells per ml of water. Total 31 taxa were found in algal mat samples: Cyanophyceae, 20 species; Bacillariophyceae, 4 species and Chlorophyceae, 7 taxa. Altogether a total 34 taxa were recorded from water and mat samples examined in the present study. Cyanophyceae was most abundant in the number of species representing some 65%. The following 21 taxa in addition to Paraphysomonas vestita mentioned above, are first records of occurrence in the Ongul Islands; Chroococcus dispersus, Dichothrix orsiniana, Hydrocoryne spongiosa, Lyngbya aerugineo-coerulea, L. martensiana, L. semiplana, L. purpurea, Nodularia quadrata, Phormidium antarcticum, P. bohneri, P. fragile, P. frigidum, P. incrustatum, P. uncinatum, Schizothrix coriacea, Xenococcus schousboei, Ulothrix mucosa, Palmodictyon viride, Microspora stagnorum, Pleurococcus antarcticus and Sphaerocystis schroeteri var. nivalis.
