“…The number of fossils attributed to Dryopteridaceae remains scarce, and to date no fossils of polystichoid ferns have been described (Collinson, 2001). Furthermore, most of the Dryopteridaceae fossils have been attributed to Dryopteris although they lack clear apomorphic characters, making their phylogenetic placement uncertain even at the family level (Collinson, 2001;Serbet and Rothwell, 2006;Vera, 2010). Consequently they were not used to calibrate the phylogeny of Dryopteris (Gandolfo et al, 2008;Sessa et al, 2012a).…”

“…(Blechnaceae; eupolypods II) was described from the Palaeocene (the Big Multi Quarry and associated strata in the uppermost Fort Union Formation of the Washakie Basin from the southwestern Wyoming; Wilf et al, 1998) and was reported as widespread from throughout the Paleogene (Collinson, 2001). We applied a conservative minimum age of 55.8 Ma to the divergence between Blechnum and Woodwardia (Fig.…”

“…Os trabalhos mais recentes de filogenia com Cyatheaceae, realizados por Korall et al (2006Korall et al ( , 2007, demonstraram que Cyathea (gênero que reúne a maioria das espécies neotropicas da família) é o grupo mais antigo e basal da família, com provável origem na Australásia, há ca. 200 milhões de anos (Collinson 2001). Todavia, nesses estudos as espécies brasileiras não foram incluídas e, consequentemente, a posição delas permanece incerta.…”

Abstract:The present checklist used as base the list of lycophytes and ferns of São Paulo State, extracted from the Catálogo de Plantas e Fungos do Brasil published in 2010, by the Jardim Botânico do Rio de Janeiro (JBRJ). An update of this list is here presented and some novelties improved the base list. The current total number of taxa for the state, including both plant groups, increased from 561 to 573. Two new records were recently reported to the state and were also added to the present checklist (Pellaea flavescens Fée and P. ovata (Desv.) Weath.). These data suggest that more studies are necessary to know the diversity in the state.

“…7). But an ecological interpretation of Leiotriletes is equivocal since spores of this type occur not only in Lygodium (Schizaeaceae) but also in the families Dicksoniaceae and Matoniaceae (Collinson 2001). Nevertheless, the distribution of Hydrocharitaceae pollen and fern spores indicates extended areas of shallow water and herbaceous swamps around the lake at this early stage of the Middle Messel Formation.…”

The Palaeogene was the most recent greenhouse period on Earth. Especially for the Late Palaeocene and Early Eocene, several superimposed short-term hyperthermal events have been described, including extremes such as the Palaeocene-Eocene Thermal Maximum. Major faunal and floral turnovers in the marine and terrestrial realms were recorded in association with these events. High-resolution palynological analysis of the early Middle Eocene maar lake sediments at Messel, near Darmstadt, Germany, provides an insight into the dynamics of a climax vegetation during the Middle Eocene greenhouse climate in a time span without significant climatic excursions. Numerical techniques like detrended correspondence analysis and wavelet analysis have been applied to recognize cyclic fluctuations and long-term trends in the vegetation through a time interval of approximately 640 kyr. Based on the numerical zoning of the pollen diagram, three phases in the development of the vegetation may be distinguished. Throughout these phases, the climax vegetation did not change substantially in qualitative composition, but a trend towards noticeably less humid conditions probably in combination with a drop of the water level in the lake may be recognized. A shift in algal population from the freshwater dinoflagellate cyst Messelodinium thielepfeifferae to a dominance of Botryococcus in the uppermost part of the core is interpreted as a response to changes in acidity and nutrient availability within the lake. Time series analyses of pollen assemblages show that variations in the Milankovitch range of eccentricity, obliquity and precession can be distinguished. In addition, fluctuations in the sub-Milankovitch range are indicated. This demonstrates that floral changes during steady depositional conditions in the Middle Eocene of Messel were controlled by orbital forcing.
