This articledealswith auniquemass-occurrenceofMyrica fromPitsidia (southernCrete,Tortonian).Foliage, fruits and infructescences as well as male catkins are preserved as imprints, sometimes coated by an iron-rich encrustation exhibiting systematically relevant morphological details. Leaves are assigned to Myrica lignitum (Unger) Saporta, fruits sometimes even attached to their infructescence axis to M. ceriferiformis Kownas, and male catkins to M. cf. goeppertii Kohlman-Adamska, ZiembińskaTworzydło & Zastawniak. The taphonomic evidence indicates that the different plant organs derive from a single species of Myrica. The fruit size, the unbranched male catkins and mainly the fused filaments into a staminal column in the male flower, clearly pointing towards the section Cerophora (sensu Chevalier 1901) of the subgenus Morella. This points to a closer affinity to the American, African and Macaronesian species ofMyrica than to Asian ones.Myrica cerifera L. is supported as the most similar living relative in terms of gland density on the leaf surface, fruit morphology and male catkin form. The infructescence axes bearing M. ceriferiformis fruits are, however, longer with a higher number of fruits than inM. cerifera. Contrary toM. cerifera, inM. cf. goeppertii the catkins are somewhat longer and the staminal column is shorter than its floret bract.Myricawas probably a dominant taxon along withPinus in an early successional stage of near-coastal wetland forests in the surroundings of Pitsidia. In southeasternNorthAmerica, modern early successional Pinus palustris forests withMyrica cerifera as a differential species serve for comparison.

The fossil floras described by Dieter Mai and Harald Walther are invaluable for understanding the past plant diversity in Europe, and provide important information on the occurrence of taxa in the fossil record that is critical for evolutionary studies. Among the taxa they recognized were seeds assigned to the extant genus Alpinia Roxb. (Zingiberaceae, Zingiberales). We reinvestigated 28 specimens that were assigned to Alpinia arnensis (Chandler) Mai, Alpinia cf. arnensis, and Alpinia bivascularis Mai from the Ypresian (lower Eocene) of the UK, upper Eocene of Germany, and lower Miocene of Germany using non-destructive synchrotron-based X-ray tomography to reveal internal anatomy. None of the samples studied show an anatomy consistent with extant Alpinia or even Zingiberales. The fossils lack the globose shape, often striate external surface, seed coat structure, operculum, and micropylar collar seen in all Alpinia, and lack the chalazal chamber seen in many Alpinia species. Two specimens from the lower Miocene of Germany showed the structure of fruits of Caricoidea Chandler (Cyperaceae) with a single-layered exocarp, thick mesocarp, and sclerified endocarp. The other specimens are recognized as Carpolithes albolutum nom. nov. (incertae sedis) from the Ypresian of the UK, C. phoenixnordensis sp. nov. (incertae sedis) from the upper Eocene of Germany, C. bivascularis comb. nov. (incertae sedis) from the lower Miocene of Germany as well as indeterminate tegmens from the lower Miocene of Germany. This reinvestigation demonstrates that there is, as yet, no confirmed fossil record for the extant genus Alpinia. Furthermore, at least four different taxa are recognized from what had been two extinct species, enhancing our understanding of these important European Cenozoic carpofloras.

Petrifiedwoods ofBombacoxylon owenii (Malvaceae /Bombacoideae),Cynometroxylon sp. cf.C.holdenii (Fabaceae /Caesalpinioideae) and Dipterocarpoxylon africanum (Dipterocarpaceae) are described from the early Miocene of Egypt. Fossil wood related to Dipterocarpaceae is a new record to Egypt while that ofCynometroxylon sp. cf.C. holdenii is new to the African flora. A warm tropical palaeoclimate withminor seasonality in precipitation is suggested for the original growth site. A list of 147African species of Fabaceae, 16 of Malvaceae and 7 of Dipterocarpaceae is given with remarks.

Late Cretaceous (Coniacian, mostly late Coniacian; ammoniteand inoceramid-based stratigraphy) leaf floras from theNysa Kłodzka Graben in the Sudetes (south-western Poland) are described. Plant remains are preserved in coarse clastic rocks as imprints devoid of cuticles and occur in marginal marine sediments deposited by a palaeocurrent flowing along the shores of the East Sudetic Island, the origin place of the plants. The main fossil plant localities are Idzików (Kieslingswalde) and NowyWaliszów (Neuwaltersdorf ). The leaf flora consists of thirty-three species, described on the basis of about 320 identifiable specimens. Five fern species (belonging to Nathorstia, Monheimia, cf. Anemia, and Sphenopteris) are mostly represented by single specimens. Conifers are represented by Geinitzia reichenbachii (Geinitz) Hollick & Jeffrey and Frenelopsis aff. alata (K. Feistmantel) Knobloch (foliage) and Geinitzia cf. schlotheimii L. Kunzmann, Knoll&Gaipl andConago sp. (cones). The bulk of the flora consists of twenty-four dicot species, representing the generaDryophyllum, Juglandiphyllites,Dalbergites,Debeya (all the above Eudicotyledoneae),Cinnamomoides, Laurophyllum, Magnoliphyllum, Ficonium, Ettingshausenia, Amelanchites, Dryandroides, Apocynophyllum, Salicites, and Dicotylophyllum (Dicotyledoneae incertae sedis). Dryophyllum geinitzianum (Goepp.) Halamski & J. Kvaček comb. nov. is sufficiently well preserved to allow a detailed reconstruction: it is a compound trifoliolate leaf composed of folioles with irregularly serratemargins; it belongs to theorderFagales s.l.Twonewspecies aredescribed.Dicotylophyllummontis-nivium sp.nov. is characterised by ovate leaves that are entire-margined in most specimens, whereas in some they possess single large teeth.Dicotylophyllum thaddaeiguniae sp. nov. is elliptic in shape, entire-margined, but has a peculiar rectangular base reminding of that of Credneria senonensis (Knobloch)Němejc&Kvaček. GeneraDalbergites,Cinnamomoides,Magnoliphyllum, and Ficonium are emended.Monocots are represented by Pandanites cf. spinatissimus Petrescu & Duşa ex Popa et al. and Smilacites panartius (Bayer) Halamski & J. Kvaček comb. nov. The most common species in the studied material are Laurophyllum acuminatum (Goepp.) J. Kvaček&Halamski comb. nov. and Dryophyllum geinitzianum (the two representing about half of the material), both presumably dominating a riparian forest. Upland or mesophilousvegetationmightbe representedbyAmelanchites cerasiformis (Vel.)Halamski&J.Kvačekcomb.nov.,Dicotylophyllum montis-nivium sp. nov., and several small-leaved representatives of Dalbergites and Dicotylophyllum. Frenelopsis grew in salt marshes, whereas Pandanites andGeintizia belong to back swamp vegetation. The studied flora belongs to the subtropical vegetation belt and is most similar to slightly older or younger (Turonian to Santonian) assemblages from the BohemianCretaceous Basin. Notable similarities with the flora of the Cenomanian to lower Coniaci
晚白垩世(Coniacian，大部分是晚Coniacian;描述了苏台德山脉(波兰西南部)theNysa Kłodzka地槽的叶区系。植物残骸被保存在粗糙的碎屑岩中，作为没有角质层的印记，并出现在边缘海洋沉积物中，这些沉积物是由沿着东苏台德岛海岸流动的古洋流沉积的，东苏台德岛是植物的发源地。化石植物主要分布在Idzików (Kieslingswalde)和NowyWaliszów (Neuwaltersdorf)。叶植物区系由33个物种组成，根据大约320个可识别的标本进行描述。5种蕨类植物(分别属于Nathorstia、Monheimia、cf. Anemia和Sphenopteris)大多为单一标本。以针叶树为代表的有Geinitzia reichenbachii (Geinitz) Hollick & Jeffrey和Frenelopsis aff.alata (K. Feistmantel) Knobloch(叶)和Geinitzia (schlotheimii L. Kunzmann, knol&gaipl和conago sp.(球果)。大部分植物区系由24种双子叶属植物组成，分别为:ryophyllum、juglanddiphyllites、Dalbergites、Debeya(以上均为真子叶科)、Cinnamomoides、Laurophyllum、Magnoliphyllum、finiconium、Ettingshausenia、Amelanchites、Dryandroides、Apocynophyllum、Salicites和Dicotylophyllum(双子叶科)。黄叶树(Dryophyllum geinitzianum)Halamski & J. kva ek梳子。十一月保存得很好，允许详细的重建:它是一个复合的三叶，由小叶组成，有不规则的锯齿边缘;它属于理论家fagales s.s。描述了两个新种。Dicotylophyllummontis-nivium sp.nov。特点是卵形的叶子，在大多数标本中是全缘的，而在一些标本中它们具有单个大牙齿。双子叶(diotylophyllum thaddaeiguniae sp. 11 .)的形状为椭圆形，全缘，但有一个特殊的矩形基部，使人想起creneria senonensis (Knobloch) n mej&kva ek。修订了albergites、Cinnamomoides、magnoliphylum和finiconium。单科植物的代表有Pandanites cf. spinatissimus Petrescu & du a ex Popa等人和Smilacites panartius (Bayer) Halamski & J. kva ek comb。11 .研究材料中最常见的物种是月桂(Laurophyllum acuminatum)。J. kvaek&halamski梳子。11 . and Dryophyllum geinitzianum(两者代表了大约一半的材料)，都可能统治着河岸森林。陆生或中温植被可由amelanchites cerasiformis (Vel.) halamski&j . kva ekcom .nov.代表。、双子叶属(Dicotylophyllum montis-nivium sp. nov.)，以及黄檀属和双子叶属的几个小叶代表。Frenelopsis生长在盐沼中，而Pandanites和geintizia属于沼泽植被。所研究的植物群属于亚热带植被带，与波希米亚-白垩纪盆地稍老或稍年轻的(Turonian - sanantonian)植物群最为相似。值得注意的是，在怀俄明的Cenomanian到较低的Coniacian Frontier Formation的植物区系也有相似之处。
