Abstract [en]

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.

Abstract [pt]

Foi realizado inventário florístico das árvores e arbustos da mata Ribeirão Cachoeira(233,7ha, altitude 650m, coordenadas 46°55’58’’W, 22°50’13’’S), o segundo maior e mais bem conservadofragmento de floresta estacional semidecidual do município de Campinas, SP. O solo característico é o PodzólicoVermelho Amarelo e o clima é Cwag’ de Köppen. As coletas foram feitas durante o período de agosto/1996 asetembro/1997. Foram incluídos apenas indivíduos férteis com perímetro a altura do peito igual ou superior a 9cm.Foram encontradas 175 espécies de 119 gêneros e 49 famílias. As famílias mais ricas foram Myrtaceae (14espécies), Rutaceae e Fabaceae (13), Caesalpiniaceae (11), Solanaceae (9) e Rubiaceae (8). Algumas espécies foramencontradas pela primeira vez na região: Tachigali multijuga Benth. e Schoepfia brasiliensis A.DC. A floração foimaior entre agosto e outubro. A frutificação foi maior nos meses de agosto a novembro. A maioria das espéciesencontradas é zoocórica (58%), as anemocóricas foram 23% e as autocóricas 19%. Compararam-se as relaçõesflorísticas desta mata com outros 20 levantamentos do Estado. Os resultados obtidos indicaram a formação de doisgrupos distintos. O mais homogêneo deles inclui as florestas do município de Campinas, mostrando que,possivelmente, são remanescentes de uma vegetação originalmente contínua.
