IVANAUSKAS, NATÁLIA MACEDO  and  RODRIGUES, RICARDO RIBEIRO. Floristic and phytosociology of remnants of deciduous seasonal forest in Piracicaba, São Paulo State, Brazil. Rev. bras. Bot. [online]. 2000, vol.23, n.3, pp.291-304. ISSN 0100-8404.

This study was conducted in two remnants of deciduous seasonal forest with 4 and 10 ha, in Piracicaba, São Paulo State, Brazil. This forest has peculiar abiotic characteristics, growing on inceptisol, with hydric deficit in the dry season and water excess in the wet season determining a peculiar flora and a physiognomy similar to the dry forests. A floristic survey was carried out in both remnants while a phytosociological was carried out in the10 ha remnant, where the individuals with PBH ³ 15 cm, present in 43 plots of 10 x 10 m, were recorded. One hundred and ten species, 86 genera and 42 families were registered. We found 20.7% of the species bearing spines, 31.0% of the 894 individuals registered had ramification at the soil level, and in the dominant stratum there were species that lose leaf turgescence (24.7% of individuals), and deciduous (59.4%), leafless (13.3%), perenial (1.6%) and semi-deciduous species (1.0%). The families with the highest number of species were Leguminosae, Myrtaceae and Rutaceae. The most important species were Cereus hildmanianus, Eugenia florida, Eugenia uniflora, Pseudobombax grandiflorum and Sebastiania serrata. The Shannon’s diversity index (H’) was 3.0 nats/individuals and the eqüability (J) was 0.7 nats/indivíduos.

Keywords : Deciduous seasonal forest; dry forest; floristic; phytosociology.
