Floristic composition and dispersal syndromes were determined along one year in an open ombrophilous forest fragment in the Municipal Park of Macei車, Alagoas State, Brazil. A total of 178 species belonging to 61 families were examined. Fabaceae was the most species-rich family, with 24 species. Among sampled species, 123 had their syndromes of diaspore dispersal determined, and most of them (69%) were zoochoric. Anemochoric and autochoric plants represent 11 and 20% from the total, respectively. The data about reproductive phases indicate coincident peaks of flowering and fruiting in August, at the end of the rainy season. The results are in accordance to those expected for ombrophilous forest with poorly defined seasonality. A composi o flor赤stica e as s赤ndromes de dispers o foram determinadas no presente estudo, ao longo de um ano, em um fragmento de floresta ombr車fila aberta no Parque Municipal de Macei車, Estado daAlagoas. Foram amostradas 178 esp谷cies, pertencentes a 61 fam赤lias. Fabaceae foi a fam赤lia de maior riqueza flor赤stica, com 24 esp谷cies. Das esp谷cies coletadas, 123 tiveram sua s赤ndrome determinada e a maioria delas (69%) 谷 zooc車rica. As plantas anemoc車ricas e autoc車ricas representam 11 e 20%, respectivamente. Os dados sobre a fase reprodutiva apontam um pico de flora o e de frutifica o coincidente, no m那s de agosto, no final da esta o chuvosa. Os resultados encontrados est o de acordo com o esperado para florestasombr車filas de sazonalidade pouco evidente.
