Composição florística de remanescente de cerrado sensu stricto em Botucatu, SP

Abstract

A floristic survey of a "cerrado" sensu stricto area was carried out in Botucatu, west-central region of São Paulo State, southeastern Brazil. One-hundredseventy-nine angiosperms taxa (177 species) were recorded distributed in 122 genera and 49 families. Five species of pteridophytes were also collected, belonging to four genera and two families. The woody component was predominant, representing more than 60% of the registered species. The arboreal to non-arboreal species ratio was 1:3. The families with the highest species richness were: Asteraceae (27 species), Fabaceae (22), Myrtaceae (11). The comparison among six cerrado areas revealed great floristic heterogeneity since the similarity indexes produced low values, even among neighboring areas.
