Pollen grains preserved in sediments are excellent for paleoenvironmental reconstitution because they indicate the plant origin and its environment. For such reconstitutions, reference palynological catalogs serve as the basis for the taxonomic determination of such preserved material. This study was performed to provide reference pollen for future paleoenvironmental studies. Here, we present taxonomic descriptions of 35 angiosperm pollen taxa, extracted from two Quaternary sedimentary profiles: Pirataba forest profile (29 degrees 15'S-49 degrees 51'W) and Faxinal forest profile (29 degrees 21'S-49 degrees 45'W), Torres Municipality, extreme northern coastal plain from Rio Grande do Sul, corresponding to the last 23,000 years according to radiocarbon dating. Ecological data and pollen illustrations accompany the taxonomic descriptions. The analysis provided distinct reference pollen taxa from varied habitats for paleoenvironmental studies of the last millennia in deposits of the coastal plain of Rio Grande do Sul, Southern Brazil.
