A descriptive atlas of pollen and spores from plants of Caí river Valley aimed to facilitate the identification of dispersed palynomorphs in fossil sediments and provide data for environmental management actions. The atlas presents 93 characteristic species of four Caí river valley plant associations, including Floresta Ombrófila Mista, Floresta Estacional Decidual, Floresta Estacional Semidecidual and Estepe, besides exotic plants and disturbed sites. In this first part, detailed descriptions and light micrographs of 24 species, 21 genera, and 17 families were included.
