Aquatic macrophytes are vascular plants that commonly occupy floodplain and wetland areas. They play an extremely important role in the functioning of the ecosystems in which they occur, being able to establish a strong connection between the aquatic system and the terrestrial environment that surrounds it. Considering that the Amazon presents a great diversity of these plant species, we conducted a field survey to assess the macrophyte species composition in the São José community, located at the municipality of Benjamin Constant, state of Amazonas, Brazil. Specimen collection, exsiccates and photographic records were done in order to assess the number of families and species found,  and also to illustrate and describe the aquatic macrophyte species according to their morphology, to classify them according to their growth form and identify what morphological structures are responsible for their adaptation in their aquatic environments. 36 species belonging to 24 families were identified. Thus, the research here conducted obtained sufficient amount of data for the future production of an illustrated guide to aquatic macrophytes of the study area and to initiate further studies in the river Solimões, providing informations about this group of plants.Keywords: Growth form; Adaptive structures; aquatic herbaceous; Araceae; Macrophytic organisms.
