Resumo

Alismataceae consists in a family of semi-aquatic or aquatic plants occurring in swamps, rivers and lakes. Currently, 11 genera are considered, with 75 species in the world. However, there is a lack of taxonomic consensus to recognize and allocate the species in the genera and palynology can act as a tool to assist in the identification and organization of this family. This study aimed to describe the pollen morphology of Alismataceae species available in the herbariums Vasconcelos Sobrinho (PEURF / UFRPE), Geraldo Mariz (UFP / UFPE) and of the Agronomic Institute of Pernambuco (IPA). In addition we collected informations in the literature about pollinators of the species analyzed. Acetolysis was performed for species available in the PEUFR Herbarium collection (n = 5). For the other classified species, pollen descriptions were used based on searches in the literature. Twenty-nine species were found in the three herbariums. Acetolysis proves efficient to be used as one of the parameters for delimiting the taxon at the level of genus or species for this family. Protodiscelis spp. bees were the most commonly cited in the literature, acting as the main pollinators of Alismataceae species. KEYWORDS: Aquatic plant, Bees, Pollen.
