The paper presents spatial variation in floristic indices in the mediumsize valley of the San River. Indices of species richness and synanthropization rates were calculated for 366 1 x 1 km cartogram squares. The Spearman rank correlation coefficient was used to analyze the relationships between individual indices. Species richness in individual basic plots ranges from 102 to 391, with a mean of 248...
