IVANAUSKAS, Natália Macedo; MONTEIRO, Reinaldo  and  RODRIGUES, Ricardo Ribeiro. Phytogeographical classification of the Upper Xingu River forest. Acta Amaz. [online]. 2008, vol.38, n.3, pp. 387-402. ISSN 1809-4392.

This paper proposes the inclusion of the "Evergreen Seasonal Forest" category in the official system used to classify Brazilian forests. This proposal is based upon the floristic and physiognomic particularities of the Southern Amazonian forest, which reach a greater magnitude around the Upper Xingu River. In order to justify the inclusion, the paper reports environmental characteristics (climate, soil and hydrology) as well as floristic and physiognomic differences between the Upper Xingu River forest and both the Ombrophilous Forest from the Amazon Basin and the Seasonal Forest of the Central Plateau.

Keywords : Amazon; Tropical Rain Forest; phytogeography.
