Caatinga is an exclusive Brazilian ecosystem that is modified by human beings when they replace the natural vegetation for crops transforming it into a desert. We must understand the reproductive strategies of the species to better conserve the Caatinga. The families Leguminosae and Euphorbiaceae are the most representative in the Caatinga. The objective of this study was to define the flowering and fruiting periods of woody species of Leguminosae and Euphorbiaceae species in the Caatinga of Pernambuco. The work was done based on collections deposited in herbaria in the city of Recife: IPA, UFRPE, HST e UPF in the city Recife,. According to the month of the year, the flowering and fruiting periods of the species were classified into rainy season, dry season, the end of dry season and beginning of the rainy season, the end of rainy season and beginning of the dry season, and both rainy and dry season. From the studied species, 38 are Leguminosae and 12 are Euphorbiacae. Most species were flowering in the dry season (36%) and both the seasons (50%), respectively. Percentage of the species was significantly different among flowering period categories to Leguminosa and Euphorbiaceae. Most species of Leguminosae was fruiting in both seasons (49%). Percentage of the species was significantly different among fruiting period categories. Most species of the family Euphorbiaceae was fruiting in the rainy season (40%). However, the percentage of the species was not significantly different among fruiting period categories. Flowering and fruiting of this woody species are in accordance to studies in seasonal tropical forests.
