“…We follow the terminology of Punt et al (2007) and Hesse et al (2009). Pollen morphology can be relatively complex in Loranthaceae even within the same genus, and morphological gradients are not uncommon.…”

“…Sculpturing as seen under the SEM is typically minute but distinct, with sculptural elements usually smaller than 1.5 µm and often densely packed, in particular in the mesocolpium. Following Punt et al (2007), we use ‘micro-’ whenever elements are not larger than 1 µm (or rarely are slightly higher/wider), ‘nano-’ is used to denote sculpturing with elements smaller than 0.5 µm. ‘Granulate’ is reserved for surfaces with a sand-sputtered appearance or matrix, i.e.…”

Earlier studies indicate a strong correlation of pollen morphology and ultrastructure with taxonomy in Loranthaceae. Using high-resolution light microscopy and scanning electron microscopy imaging of the same pollen grains, we document pollen types of 35 genera including 15 studied for the first time. Using a molecular phylogenetic framework based on currently available sequence data with good genus-coverage, we reconstruct trends in the evolution of Loranthaceae pollen and pinpoint traits of high diagnostic value, partly confirming earlier intuitive hypotheses based on morphological observations. We find that pollen morphology in Loranthaceae is strongly linked to phylogenetic relationships. Some pollen types are diagnostic for discrete genera or evolutionary lineages, opening the avenue to recruit dispersed fossil pollen as age constraints for dated phylogenies and as independent data for testing biogeographic scenarios; so far based exclusively on modern-day data. Correspondences and discrepancies between palynological and molecular data and current taxonomic/systematic concepts are identified and suggestions made for future palynological and molecular investigations of Loranthaceae.

terra australis 32Terra Australis reports the results of archaeological and related research within the south and east of Asia, though mainly Australia, New Guinea and island Melanesia -lands that remained terra australis incognita to generations of prehistorians. Its subject is the settlement of the diverse environments in this isolated quarter of the globe by peoples who have maintained their discrete and traditional ways of life into the recent recorded or remembered past and at times into the observable present.Since the beginning of the series, the basic colour on the spine and cover has distinguished the regional distribution of topics as follows: ochre for Australia, green for New Guinea, red for South-East Asia and blue for the Pacific Islands. From 2001, issues with a gold spine will include conference proceedings, edited papers and monographs which in topic or desired format do not fit easily within the original arrangements.

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.
