ABSTRACT - The phytoplankton communities of 20 patagonian lakes (Argentina) were sampled during the summer of 1984. For the whole of these lakes 254 taxa were registred allowing a better knowledge of their distribution in the southern hemi- ., sphere. A selected subset of 46 dominant taxa was used to perform a cluster analysis of lakes. By taking into consideration both the abundance and distribution of phyto- plankton, two distinct groups of lakes could be distinguished: oligotrophic andean lakes on the one hand and meso-eutrophic lakes located in the preandean area and patagonian plateau.
