- An inventory of the woody flora (trees and shrubs), was carried out in the Ribeirão Cachoeria forest (233.7ha, 650m high, 46°55’58’’W, 22°50’13’’S), the second largest and best conserved fragment of semideciduoustropical forest in the municipality of Campinas, São Paulo state, Southeastern Brazil. The soil is a red-yellowpodsol and the climate is of Köppen’s Cwag type. Collections were made from August/1996 to September/1997.Only fertile individuals with a perimeter at breast height of 9cm or greater were included in the survey. Onehyndred and seventhy five species were identified, belonging to 119 genera and 49 families. The most importantfamilies were Myrtaceae (14 species), Rutaceae and Fabaceae (13), Caesalpiniaceae (11), Solanaceae (9), andRubiaceae (8). Some species were found for the first time in the region: Tachigali multijuga Benth. and Schoepfiabrasiliensis A.DC. The flowering peak for most species was from August to October. Maximum fruit productionwas from August to November. Most species are zoochoric (58%), but 23% were anemochoric and 19% autochoric.The floristic composition of this forest and another 20 forests from São Paulo state were compared. The results obtained indicate the existence of distinct groups of forests. The most homogeneus group contains forests fromthe municipality of Campinas with similarity of 40%. This suggests that these forests are possibly fragments of aoriginal continuous forest in the Campinas region.
