Conteúdo: | An analysis was made of the floristic composition of 26 cerrado areas in Brazil, encompassing most of the latitudinal and much of the longitudinal extension of this vegetation. A total of 485 species of trees and large shrubs occurred in these areas but those present at only one site were eliminated so that the number analysed was reduced to 255. Numerical classification and ordination, followed by an environmental/geographical interpretation of site patterns, were used in the analysis. The analyses revealed three major gradients of variation associated with latitude, longitude and, mst strongly, soil-type (mesotrophic or dystrophic). The study demonstrated that cerrado vegetation is extremely heterogeneous: none of the 485 species recorded occurred at all sites and only 27 were present at 15 or more. Further knowledge of this distributional heterogeneity is essential for the planning of representative conservation areas of this extremely endangered vegetation.
