This study aimed to know the phytosociology of the tree component of riparian vegetation in a stream that flows into the Sirinhaem River in Engenho Buranhem, Sirinhaem, Pernambuco State, and identify the species dispersal syndromes. The stream is located in a fragment of dense rain forest of the lowlands, with 272 ha. It was sempled used one hectare (40 sampling units of 10 m x 25 m each). It was registered 1,307 trees with circumference at breast height (CAP) . 15 cm. We identified 118 species belonging to 40 botanical families. Protium heptaphyllum and Pouteria sp.1 were the most abundant species. In terms of importance value (IV), Protium heptaphyllum, Pouteria sp.1 and Virola gardneri are among the most important ecologically species. The predominant dispersal syndromes were zoocory (72.8%), autocory (13.6%) and anemochory (4.8%). It was not possible to determine the type of dispersal of 8.8% of the species studied. doi: 10.4336/2012.pfb.32.69.01
