Resumo: | Parkia pendula occurs in Brazil in Amazonia and in the northeastern Atlantic Forest. In the latter, its buds, nectar, and seedpod gum are discussed to be keystone resources for the mammalian fauna. To enhance the knowledge about these important nourishment sources, the aim of this study was to detect and describe distinct phases in the flower and pod development. The study was conducted in a 306 ha forest fragment in Igarassu, Pernambuco, northeastern Brazil. Six morphometrical variables were measured weekly at five inflorescences of two individuals from September 2003 to January 2004. Eleven distinct developmental phases were identified in the 21 weeks lasting development from the very first inflorescences to mature pods and are described in detail. These phases are good predictors for the flowering and fruiting phenology of P. pendula, since they are easily distinguishable from the forest floor. Furthermore, highly synchronized abortions of inflorescences, buds, and pods were observed which support the previously assumed predator satiation defense strategy in Parkia.
