Differencesareas) in Patrânia, in species São number Paulo andstate, proportion southeastern of the Brazil, woody concerning and herbaceous the floristic components composition. were observed In total, among 250 taxa the threewere Cerrado areas. The similarity analysis revealed that the cerradão seems quite peculiar, showing low similarity level with the cerrado sensu stricto areas contiguous to it, being more similar to other cerradão areas located in nearby municipalities. Introduction physiognomic diversity become very important because According to Coutinho (1978, 2002), the Cerrado they can support future actions of management, restoration (Brazilian savanna) is a vegetation complex encompassing and conservation in the Cerrado region, also expanding
