RESUMO(Grãos de pólen de angiospermas do Holoceno (7908±30 anos AP-atual) da Planície Costeira sul-catarinense, Brasil). Este trabalho apresenta as descrições palinotaxonômicas, a partir da análise palinológica de sedimentos de duas seções turfáceas na Planície Costeira sul do estado de Santa Catarina, nos municípios de Santa Rosa do Sul e São João do Sul. Uma amostra da porção basal dos testemunhos foi datada em ( 14 C) em 7908±33 anos AP para Santa Rosa do Sul e 7817±41 anos AP para São João do Sul, ambos referente ao Holoceno inferior. Foram descritos 62 tipos de grãos de pólen relacionados a 49 famílias de angiospermas atuais, que expressam diferentes habitats e hábitos ecoló-gicos. O presente trabalho juntamente com a primeira parte, que trata das descrições palinotaxonômicas de fungos, criptógamas e outros palinomorfos recuperados de sedimentos, contribui com o reconhecimento da vegetação que abrigava a Planície Costeira sul-catarinense, durante o Holoceno. As análises palinotaxonômicas constituem a base das interpretações paleoambientais e paleoclimáticas neste setor da costa brasileira. Palavras-chave:Descrições polínicas, Quaternário, Holoceno, Planície Costeira, Santa Catarina ABSTRACT (Catalogue of angiosperm pollen from Holocene sediments of the Coastal Plain, Santa Catarina, Brazil). This paper presents palinotaxonomic descriptions, from a pollen analysis of sediments from two cores taken from the southern Coastal Plain of Santa Catarina State (in the municipalities of Santa Rosa do Sul and São João do Sul). A basal sample from the Santa Rosa do Sul and São João do Sul had a 14 C age of 7908±33 and 7817±41 yr BP for the Lower Holocene, respectively. Sixty-two types of pollen grains were described from 49 angiosperm families, which are associated with different habitats and ecological habits. This work is published in association with Part I, which comprises palinotaxonomic descriptions of fungi, cryptogams and other palynomorphs recovered from the sediments, and contributes to the identification of vegetation that occurred on the Coastal Plain of southern Santa Catarina during the Holocene. Palinotaxonomic analyses form the basis of paleoclimatic and paleoenvironmental interpretations in this region of the Brazilian coast.

Bryophyte and pteridophyte spores and other palynomorphs in quaternary marine sediments from Campos Basin, southeastern Brazil: Core BU-91-GL-05

This paper presents morphological descriptions and ecological data of cryptogam spores and other non-pollen palynomorphs from Quaternary sediments of Campos Basin, Rio de Janeiro, SE Brazil. The ages were derived from biostratigraphy of planktonic foraminifers and two radiocarbon dates, and suggest that sediment deposition started in the last 140,000 years BP. Thirty different types of palynomorphs were identified, described, and photographed: two bryophyte spores (sensu lato); 21 pteridophyte spores; four freshwater microalgae; onePseudoschizaea; and two microfungi. Some of the identified spores (Sphagnum, Blechnum, Cyatheaceae, Dennstaedtiaceae, Lycopodiella, Microgramma, Polypodium, Acrostichum, Pityrogramma, and Lygodium) are related to the modern flora found on the northern coast of Rio de Janeiro State, at the Restinga of Jurubatiba, from vegetation types such as shrub swamp/ coastal swamp formation, seasonally flooded forest, Clusia and Ericaceae woods, and disturbed vegetation. The freshwater microalgae and the microfungi are also presently recorded from the coastal lagoons of this region. The high spore concentration in slope sediments reflects the intense terrigenous influx, caused by a relative low sealevel during glacial stages. Palynological analysis suggests the presence of taxa from flooded forests and humid areas in the coastal plain during glacial and interglacial stages of the Late Pleistocene.

Fungi, algae, and other palynomorphs in sedimentary profiles collected from two forests in the northernmost coastal plain from Rio Grande do Sul, southern Brazil). We present, for the first time, taxonomic descriptions of 13 fungi, eight algae, three acritarchs, and nine other palynomorphs preserved in two Quaternary sediment profiles: Pirataba forest site (29°15 0 S-49°51 0 W) and Faxinal forest site (29°21 0 S-49°45 0 W), Torres Municipality, northernmost coastal plain from Rio Grande do Sul, southern Brazil. We aimed to provide taxonomic reference material for paleoenvironmental studies in the region. The profiles were collected using a Hiller Sampler, with a maximum interval of the last 23,000 years (according to radiocarbon dating). The samples were processed using HCl, HF, KOH, and acetolysis. Prepared specimens were examined by light microscopy. The palynomorphs were found during counts of a minimum of 300 angiosperms pollen grains in each sample (minimum number determined by plotting saturation curves). We present descriptions and illustrations of palynomorphs and relevant ecological data for the taxa. The high taxonomic diversity found will enable further studies of the vegetation and climatic changes on the northern coastal plain of southern Brazil.
