Abstract The Blechnaceae is a family of leptosporangiate ferns with a wide geographical distribution. Recent phylogenies revealed several lineages within the family, culminating in a classification system comprising 25 recognized genera grouped into 3 subfamilies. Spore surface morphology has major importance in the taxonomy of the group, but there is limited information on the relevance of other palynological

ABSTRACT Little information about the contribution of plants to the production of honey by bees exists for southern Brazil. Information on this dynamic is crucial to maintaining the health of bees, the pollination of forests and assisting in the management of apiaries and meliponaries. The objective of the study was to elucidate which plants the bees visit for the production of honey in Rio Grande

Abstract The different geographic origins of Baltic, Bitterfeld and Ukrainian ambers may be reflected in differences in their encased fungal spores and plant pollen. In this study, over 573 palynomorphs were isolated through solvent extraction and the differences in their morphological characteristics examined using conventional transmitted light microscopy to explore this hypothesis. The spore spectra

Abstract Lippia L. is the second largest genus in the family Verbenaceae, comprising approximately 100 species widely distributed in the Neotropics and with some representatives in Africa. The genus is considered poorly delimited taxonomically because many species can only be distinguished by minor morphological differences, resulting in a large number of described taxa. This study aimed to examine

The upper Paleocene-lower Eocene Margaret Formation exposed at Stenkul Fiord on southern Ellesmere Island, Nunavut, Canada, represents a nearly continuous terrestrial succession of microfossil-rich clastic sediments and coal. These strata were deposited at a time of extensive tectonic activity associated with Eurekan deformation. The precise chronology of the Eurekan deformation is poorly known. Prior

Cyclonephelium brevireticulatum is a new organic-walled dinoflagellate cyst described from the upper Maastrichtian Arkadelphia Formation, Hot Spring County, Arkansas. Cyclonephelium brevireticulatum sp. nov. is distinguished from other species of this genus by its small size, and by processes of very low relief (< 5 µm) which connect linearly to form a chain or mesh-like micro-reticulation along the

The succession at Punta Ainol represents a new record for the Paleogene (late Paleocene-middle Eocene) from southern South America, based on current data on nannofossil and dinoflagellate cysts. Some significant events are in agreement with

Abstract A new monosulcate species, Shanbeipollenites lagarcitensis sp. nov. is described from the Lower Cretaceous Lagarcito Formation, Sierras de Guayaguas (North–western San Luis Basin), Argentina. Shanbeipollenites lagarcitensis shares with other species of this genus a broadly ellipsoidal outline and a diagonally disposed distal sulcus. However, the new species differs from the psilate type species

Abstract The Cenozoic of the North Sea is among the best-documented stratigraphical successions in the world, and multiple palynological events have been recognised for chronostratigraphical control across the region. The ever-increasing number of wells studied for hydrocarbon exploration and production results in the generation of new biostratigraphical data that constantly increase our palynological

Abstract The palynoflora and organic petrography of core samples from the Tyler Formation in the Williston Basin, North Dakota, USA were evaluated to determine their age and depositional environment. The palynofloras are assigned to seven plant groups used by previous authors who studied Carboniferous floras. Lycopsid trees, represented by Lycospora species and Crassispora kosankei are the most abundant

Abstract The Pin Formation of the northern Indian Himalaya may contain a record of the late Katian (Late Ordovician) warming event (the Boda Event). Palynological samples collected from two members of this formation are investigated in order to evaluate the biostratigraphical potential of the different microfossil groups. Acritarchs and chitinozoans are the most abundant microfossils, but fragments

A total of 31 pollen types, belonging to 20 botanical families were identified as pollen sources of T. biroi. Adonidia merrilli Becc. and Cocos nucifera L. were consistent predominant

Since the publication of five literature compilations issued between 2012 and 2020, 63 further published contributions on Triassic, Jurassic and earliest Cretaceous (Berriasian) dinoflagellate cysts have been discovered, or were issued in the last 14 months (i.e. between February 2019 and March 2020). These studies are on North Africa, Southern Africa, East Arctic, West Arctic, east and west sub-Arctic

Abstract This study focuses on five cores in and around three of the hundreds of shallow ephemeral hypersaline lakes distributed in chains along traces of ancient drainages that dominate the southern Western Australian landscape. Cores within and on the shore of Lake Aerodrome (LA1-09, LA2-09), Prado Lake (PL1-09, PL2-09), and Gastropod Lake (GLE1-09) in the Cowan Paleodrainage were drilled as part

Abstract As one of the remaining living links with two early Scandinavian researchers, the author examines their contribution to Bill Evitt’s breakthrough that launched the development of fossil dinoflagellate cysts into palynology. Evitt, in the early 1960s, revealed that many fossil hystrichospheres were in fact dinoflagellate cysts. Trygve Braarud, a Norwegian phytoplankton biologist, and Gunnar

Abstract A detailed palynological study was conducted in the lower Palaeozoic of the Zagros Basin (southwestern Iran) where the Mila and Ilbeyk formations are present in several areas. The Mila Formation mainly consists of dolostones, limestones and shales deposited in a shallow marine to outer ramp environment. It is conformably overlain by the Ilbeyk Formation, characterised by shales and sandstones

Abstract Methodological papers advise to collect moss surface samples either at the beginning or at the end of the flowering season. In reality, such collections occur often within the flowering season for purposes of vegetation description or because of accessibility of remote study areas. Here we test whether the season of moss surface sample collection has an influence on pollen spectra. Ten moss/litter

Abstract Seven semi-consolidated surface sediment samples from the tidal flats along the southern Red Sea coast of Saudi Arabia were studied for their palynomorph assemblages. These samples are mainly clay and fine sand and yielded low numbers but high diversity of palynomorphs. They have various affinities and have been divided into five groups: (A) pollen and spores; (B) dinoflagellate cysts and

Abstract In western Amazonia, palynology has been the main source of chronological information for the Neogene Period. The Solimões Formation in northwestern Brazil has hundreds of meters of fine-grained rocks that have yielded rich pollen records informing on age and paleoenvironments. Here, we present new pollen data for two boreholes (1-AS-33-AM and 1-AS-37-AM) in the Solimões Basin and one outcrop

Abstract A new dinoflagellate cyst genus and species are described here as Hiddenocysta gen. nov. and Hiddenocysta matsuokae sp. nov. from Holocene sediments in a core from the west coast of Vancouver Island (British Columbia, Canada). The genus Hiddenocysta encompasses spherical to ovoid skolochorate cysts, characterized by a gonyaulacoid plate pattern and a 2P precingular archeopyle. The species

This paper presents the formal description of Impagidinium obscurum sp. nov. from the Thanetian strata of northwest Europe. The palaeogeographic distribution of this species covers a wide area, ranging from the North Sea to the Barents Sea. Palynologists working in the region have long referred to Impagidinium obscurum sp. nov. as Leptodinium? ‘obscurum’ and used it as an important intra-Paleocene

Pollen grains of primitive varieties of Hordeum vulgare collected by the Gene Bank of the Crop Research Institute, Prague, are compared to pollen of native Glyceria species of the United Kingdom with a view to establishing separation criteria. It is found that a separation of Hordeum vulgare from both Glyceria maxima and Glyceria fluitans is possible according to annular characteristics in combination

This article presents a reconstruction of Late Holocene vegetation changes within the lower montane forest zone in the Beskid Wyspowy Mountains (Western Carpathians, Central Europe). Pollen, non-pollen palynomorphs, loss on ignition, and microscopic charcoal analyses were applied to a profile collected from the deposits of the rich fen which developed in the landslide depression. The results reveal

Melissopalynological studies are useful to determine the floral contents and geographical origin of honey samples. The great botanical diversity in the Amazon allows bees to produce honey that is highly valuable in Peruvian culture. However, pollen analyses and labels that provide information on honey contents are scarce; therefore, people do not know what types of honey they are consuming and paying

The palynological sequence in core QZMS from Qizimei Mountain, central China, reflects the vegetation and climate dynamics since 12,900 calibrated years before present (cal yr BP). A palynological analysis demonstrated that the temperate deciduous broadleaved and coniferous mixed forest that was present from 12,900 to 10,600 cal yr BP changed to a deciduous broadleaved and coniferous mixed forest from

The taxonomy of the dinoflagellate cyst-based genus Votadinium has been in need of revision. This is accomplished here by integrating morphology, large subunit (LSU) rDNA sequences, and cyst wall composition analyses through micro-Fourier transform infrared spectroscopy. Three new species, Votadinium pontifossatum, V. rhomboideum and V. reidii, are described as cyst stages of Protoperidinium paraoblongum

Forty-four rock samples from the Landana section, belonging to the historical Dartevelle collection of the Royal Museum for Central Africa (RMCA) at Tervuren, Belgium, were palynologically processed and analysed. Systematic analysis of the samples from the Landana sea cliff locality has revealed 90 dinoflagellate cyst taxa spanning an interval that ranges at least from the middle Paleocene to the late

The present study aims to document modern pollen assemblages and compare them with the extant vegetation, through palynological analysis of 40 modern moss cushions, from the Akhnoor sector of Jammu District (Jammu and Kashmir), India. The study revealed that the pollen of Pinus sp. (average 62%) dominates the pollen assemblages. The over-representation of Pinus pollen could be attributed to its high
