The fossil flora from brackish late Burdigalian (Ottnangian) sediments in Brno-Líšeň (the Czech Republic) contributes to our knowledge of floristic evolution and palaeoclimatic changes in the Western Carpathians. The fossil material investigated for this study comprises fragmentary leaf imprints, few fruits/seeds, and dispersed pollen from a single palynomorph-rich sample. Macro remains include 3 ferns (Osmunda parschlugiana, Salvinia reussii, ?Polypodiaceae gen. et sp. indet.) and 17 angiosperms (e.g., Daphnogene polymorpha, “Parrotia” pristina, Leguminophyllum spp., Podocarpium podocarpum, cf. Engelhardia orsbergensis, Ulmus sp., Schoenoplectiella cf. ragozinii). The palynospectrum comprises 106 taxa, including abundant palaeotropical elements of zonal evergreen forest, i.e., Sapotaceae, Palmae, Engelhardia, Platycarya, Fagaceae, Araliaceae and Cornus-Mastixia, accompanied by arctotertiary elements of deciduous zonal forest (Quercus, Carpinus, Fagus, Carya, Juglans, Tilia, Betula, Parrotia) and deciduous azonal (riparian) forest (e.g., Alnus, Salix, Ulmus). Aquatic plants, algae (Prasinophyceae, Botryococcus) and marine dinoflagellates indicate a marine environment with freshwater impact. Plant taxa possibly representing open areas such as Olea, Celtis, Buxus, Ephedra, Rosaceae and Poaceae are sporadic, as well as conifers of extrazonal forest such as Cedrus, Tsuga, Picea. The studied palynospectrum contains abundant thermophilic elements and does not point to a cooling event, as reported by previous authors from the Polish part of the Carpathian Foredeep.
来自Brno-Líšeň(捷克共和国)的半咸晚期burdigian (Ottnangian)沉积物的化石植物群有助于我们了解西喀尔巴阡山脉的植物群演化和古气候变化。本研究调查的化石材料包括破碎的叶片印记，少量的果实/种子，以及来自一个富含花粉形态的样品的分散花粉。大型遗存包括3种蕨类植物(Osmunda parschlugiana, Salvinia reussii， ?Polypodiaceae gen. et sp. indet.)和17种被子植物(如:多形植物，“Parrotia”pristina，豆科植物，Podocarpium podocarpum, cf. Engelhardia orsbergensis, Ulmus sp.， Schoenoplectiella cf. ragozinii)。孢粉光谱包括106个分类群，包括丰富的地带性常绿森林古热带成分，如saptaceae、Palmae、Engelhardia、Platycarya、Fagus、Carya、Juglans、Tilia、Betula、Parrotia)和落叶地带性(河岸)森林(Alnus、Salix、Ulmus)。水生植物、藻类(Prasinophyceae、Botryococcus)和海洋鞭毛藻表明海洋环境受淡水影响。可能代表开阔地区的植物类群为零星分布的，如油橄榄科、石竹科、黄杨科、麻黄科、蔷薇科和禾科，以及地带性森林外的针叶林，如杉木科、杉木科、云杉科。研究的孢粉谱含有丰富的嗜热元素，并不像以前的作者在喀尔巴阡前深的波兰部分所报道的那样，指向一个冷却事件。

Following on the seminal works of Reid and Chandler in 1933 and Chandler in 1961, morphology and anatomy of fossil mastixioid fruits from the early Eocene London Clay of southern England were reanalyzed with the benefit of new methods in comparison with extant genera of Mastixiaceae and with other fossil representatives from Europe and North America. The species named Mastixia cantiensis E.Reid et M.Chandler was based on a heterogeneous assemblage of specimens, all representing Mastixiaceae, some of which truly represent Mastixia whilst others correspond to Diplopanax and Mastixiopsis The holotype of M. cantiensis E.Reid et M.Chandler corresponds to extant Diplopanax rather than Mastixia. Therefore, this species is moved out of Mastixia and is treated as Diplopanax cacaoides (Zenker) comb. nov. Nine species of mastixioid fruits are currently recognized in the London Clay flora: Mastixia parva E.Reid et M.Chandler, M. cf. oregonensis (R.A.Scott) Tiffney et Haggard, Diplopanax cacaoides, Tectocarya grandis (E.Reid et M.Chandler) comb. nov., Mastixiopsis nyssoides Kirchh., Exbeckettia mastixioides (E.Reid et M.Chandler) gen. et comb. nov., Lanfrancia subglobosa E.Reid et M.Chandler, Portnallia bognorensis M.Chandler, and Langtonia bisulcata E.Reid et M.Chandler. These include the oldest known representatives of the genera Diplopanax, Tectocarya and Mastixiopsis and contribute to our understanding of the former morphological diversity and palaeobiogeography of the Mastixiaceae.
继Reid和Chandler(1933年)和Chandler(1961年)的开创性工作之后，利用新的方法，对英格兰南部早始新世伦敦粘土中的乳香属化石果实的形态和解剖学进行了重新分析，并与现存的乳香科属以及来自欧洲和北美的其他化石代表进行了比较。该物种命名为Mastixia cantiensis e.r eet m.c chandler，是基于一个异质的标本组合，所有标本都代表Mastixiaceae，其中一些真正代表mastixiia，而另一些则对应于Diplopanax和Mastixiopsis . M. cantiensis e.r eet m.c chandler的完整模式对应于现存的Diplopanax而不是Mastixia。因此，该种属被移出乳香科，并被视为双翅蝶(Zenker)梳。11月在伦敦粘土植物区系中发现了9种乳脂类果实:Mastixia parva E.Reid et M. chandler, M. cf. oregonensis (R.A.Scott) Tiffney et Haggard, Diplopanax cacaoides, Tectocarya grandis (E.Reid et M. chandler) comb。11月，马尾opsis nyssoides Kirchh。，乳突棘虫(e.r idet m.c erchandler) gen. et comb.;11月，亚全球蓝腹蓝蛛E.Reid et M.Chandler, bognorensis M.Chandler，和蓝腹蓝蛛E.Reid et M.Chandler。其中包括已知最古老的Diplopanax属、Tectocarya属和Mastixiopsis属的代表，有助于我们了解Mastixiaceae以前的形态多样性和古生物地理学。

The study of a few putative palm macrofossils from the type area of the Maastrichtian Stage appeared to have important implications for understanding the composition of the fossil flora of the area, as well as for the nomenclature of fossil palm fruits in general. The type specimen of the palm fruit Palmocarpon cretaceum Miq., 1853 described from the Cretaceous of the Maastrichtian type area belongs to Nypa burtinii (Brongn.) Ettingsh., 1879 from the Eocene, most probably from the Brussels area. The material mentioned by Ubaghs (1885a, b, 1887) as Palmocarpon cretaceum does not represent fossil palm fruits. Therefore, palm pollen is the only evidence for the presence of palms (Arecaceae, or Palmae, excl. Nypa) in the Cretaceous of the Maastrichtian type area. Palmocarpon Miq., 1853 is proposed here as a nomen rejiciendum, and the genus Palmocarpon Lesq., 1878 as a nomen conservandum.

Well-preserved silicified woods from a site near the town of Post, Oregon, western USA, provide insights into the late Eocene vegetation and climate ca. 36 million years and data for comparing with both older and younger wood floras regionally and globally. The composition of this wood flora, taken into consideration along with taxa identified from silicified fruits and seeds of the same locality, provides a more complete picture of the former vegetation. We recognize woods belonging to the families Anacardiaceae (Pistacia terrazasae sp. nov.), Cannabaceae (Celtis popsii sp. nov.), Cercidiphyllaceae (Cercidiphyllum cf. alalongum R.A.Scott et E.A.Wheeler), Fagaceae (Fagus dodgeii sp. nov., Lithocarpoxylon ashwillii sp. nov., Lithocarpoxylon sp., Quercus sp.), Hamamelidaceae (Hamamelidoxylon crystalliferum sp. nov., H. cf. suzukii E.A.Wheeler et T.A.Dillhoff), Juglandaceae (Pterocaryoxylon sp.), Malvaceae (Wataria kvacekii n. sp.), Platanaceae (Platanoxylon cf. haydenii (Felix) Süss et Müll.-Stoll, Platanus sp.), Sapindaceae (Acer, 2 spp.), Trochodendraceae (Trochodendron beckii (Hergert et H.K.Phinney) R.A.Scott et E.A.Wheeler). This assemblage, which we refer to as the Post Hammer flora (UF 279), is comparable in age to the nearby Teater Road flora known mainly from fossil leaf impressions. Comparing the functional traits of the Hammer woods to the older Clarno Nut Beds woods attests to changing climate in the region, including an increase in seasonality.
美国西部俄勒冈州波斯特镇附近的一处遗址保存完好的硅化木材，提供了大约3600万年始新世晚期植被和气候的见解，以及与区域和全球较老和较新木材区系进行比较的数据。考虑到这一木材植物群的组成，以及从同一地点的硅化果实和种子中鉴定的分类群，提供了一个更完整的以前植被的画面。我们认识到的树木属于槭树科(Pistacia terrazasae sp. 11 .)，大麻科(Celtis popsii sp. 11 .)，桦树科(Cercidiphyllum cf. alalongum R.A.Scott et E.A.Wheeler)，壳壳树科(Fagus dodgeii sp. nov.， Lithocarpoxylon ashwillii sp. nov.， Lithocarpoxylon sp.， Quercus sp.)，金线梅科(Hamamelidoxylon crystalliferum sp. nov.， h.c.f uzukii e.a.w wheeler et t.a.d ilhoff)，枣树科(Pterocaryoxylon sp.)， malvacekii (Wataria kvacekii n. sp.)，Platanoxylon (Platanoxylon cf. haydenii (Felix) s ss et m ll.;-Stoll, Platanus sp.)， Sapindaceae (Acer, 2 sp.)， Trochodendron beckii (Hergert et H.K.Phinney) R.A.Scott et E.A.Wheeler)。这个组合，我们称之为Post Hammer植物群(UF 279)，在年龄上与附近的Teater Road植物群相当，这些植物群主要来自化石叶片印象。将Hammer森林的功能特征与更古老的Clarno Nut Beds森林进行比较，证明了该地区气候的变化，包括季节性的增加。

During the Miocene Climatic Optimum, a global long-term warm interval, European mid-latitude regions experienced a subtropical palaeoclimate. In particular, areas in eastern Germany were part of a vegetational zone with evergreen broadleaved forests, characterized by subtropical taxa. Regional palaeofloristic concepts denominated this palaeovegetation Younger Mastixioideae Flora sensu Mai (1964). Type assemblage is the late Early Miocene flora of Wiesa. Here, we reevaluate its floristic composition with respect to nearest living relatives of fossil-taxa, and introduce the new approach Phytogeographic Reference Region Assessment (PRRA) to ascertain the area of most similar extant vegetation for the Wiesa assemblage. The southern belt of SE Asian subtropical evergreen broadleaved forest and its transition to tropical mountain evergreen broadleaved forest in SW China represent the most similar extant vegetation. The Wiesa assemblage is compared to two diverse plant macroassemblages from the late Oligocene and the Late Miocene, respectively, coming from the same region and palaeoenvironmental setting. It is demonstrated that diversity and abundances of subtropical taxa markedly increased towards the Early Miocene, and specific climate-sensitive taxa occurred. The regional palaeoclimate was subtropical-humid (Köppen-Trewartha type Cf), with a growing season eleven months long. The late Oligocene and Late Miocene climates were mainly distinct in nine-month growing season lengths and cooler winters (1–3 °C).
在全球长期暖期中新世气候最适期，欧洲中纬度地区经历了亚热带古气候。特别是德国东部地区是常绿阔叶林植被带的一部分，其特征是亚热带分类群。区域古植物学概念将该古植被命名为Younger Mastixioideae Flora sensu Mai(1964)。类型组合为Wiesa早中新世晚期植物区系。在此，我们重新评估了其植物区系组成，并引入了植物地理参考区域评估(PRRA)的新方法来确定Wiesa组合中最相似的现存植被面积。东南亚亚热带常绿阔叶林南带及其向中国西南热带山地常绿阔叶林的过渡是现存最相似的植被。将Wiesa组合与来自同一地区和古环境背景的晚渐新世和晚中新世两个不同的植物大组合进行了比较。结果表明，早中新世亚热带分类群的多样性和丰度显著增加，并出现了特定的气候敏感分类群。区域古气候为亚热带湿润气候(Köppen-Trewartha型Cf)，生长期为11个月。晚渐新世和晚中新世气候以9个月的生长季节长度和较冷的冬季(1-3°C)为主要特征。

In the Piedmont Basin (PB), one of the northernmost Mediterranean basins recording the Messinian Salinity Crisis (MSC), pollen and plant macroremains (leaves, fruits and seeds) were studied in four sedimentary sections of the post-evaporitic interval (5.6–5.33 Ma). The joint palaeobotanical investigations of the two datasets allowed the reconstruction of a floristic assemblage which consists of 133 taxa (95 woody and 38 non-woody taxa). The lowland/coastal vegetation reconstructed by integrating macro- and microfossil data exhibits several analogies with existing “types/formations” of South-Southeast Asia, whereas taxa occurring solely in the pollen record suggest the existence of altitudinal forests with conifers and a few angiosperms. We suggest that the generalized type of lowland, zonal palaeovegetation in the post-evaporitic Messinian of the PB was of no-analog type, but most similar to either “mixed mesophytic forests” or “broad-leaved evergreen forests”, which indicates a Köppen-Trewartha subtropical palaeoclimate.

The late Early Pleistocene was the last time of equable climate in northern Central Italy, reflected in its large mammal fauna and numerous palynological records. Reliably dated leaf fossils from this time are rare, but provide crucial information on local and regional vegetation, biogeographic relationships, and species turnover coinciding with the assembly of modern forest biomes. Here we investigated a rich assemblage of leaf and fruit impressions (63 fossil-taxa) from the Oriolo quarry, Faenza (Ravenna), dated to the latest Calabrian, preserved in transgressive coastal deposits. The fossil assemblage represents riparian vegetation and xeric alluvial habitats in the lowlands and forest vegetation above the alluvial plain. Forest-building trees were deciduous, but comprised several taxa characteristic of open scrubland or forest edges. The composition of the flora reflects a dynamic process of assembling modern forest biomes in western Eurasia. While most taxa correspond to modern submediterranean and temperate woody species, some others represent late occurrences of taxa today confined to refugia outside Italy (Parrotia, Gleditsia, Pterocarya), and a few are Miocene/Pliocene relics indicating final floristic links with East Asia (Japan) and/or North America (Tsuga cf. chiarugii, Carya cf. minor) and Pleistocene endemism in Italy (Berberis auriolensis, Acer aemilianum).

Although the Miocene Clarkia locality in Idaho, USA, is a well-known fossil lagerstätte, this 16-million-year-old flora is especially renowned for its abundant leaves with excellent preservation. The exquisite condition of its dicot leaves has resulted in detailed research on systematics, morphology, venation, epidermal structure, cell ultrastructure, biochemistry, and even molecular biology. However, new discoveries continue to emerge, even after five decades of research. Here we describe the first water lily leaf from the Clarkia flora as Nymphaea sp. based on its form, petiole attachment, and venation. The eccentric peltate leaf is ovate with a cordate base, a deep basal sinus, entire margins, and actinodromous primary venation. Its small, unblemished condition and leathery texture suggests that it is a young floating leaf. While rare in the Clarkia Lake deposits, the occurrence of a single water lily leaf among tens of thousands of dicot and conifer leaves follows the taphonomic pattern of nearby Middle Miocene floras, two of which have yielded Nymphaea pollen. The recognition of Nymphaea at Clarkia supplements the taxonomic composition of the flora, confirms the presence of water lilies in region during the Middle Miocene, and completes our understanding of plant life in the Pacific Northwest 16 million years ago.
