The Oligocene palaeontological locality on Matrý Hill near Sebuzín in the České středohoří Mts., North Bohemia, belongs to the Děčín Formation and is dated to 30.8-24.7 Ma according to the regional stratigraphy. It has yielded, in addition to insects from the Heteroptera group, a fossil bee Apis petrefacta and palaeobatrachid frogs, also numerous plant remains. Their recovery began in 1996. The plant fossil assemblage consists mostly of leaf impressions, occasionally accompanied by casts or impressions of fruits. Noteworthy are records of a fern Woodwardia muensteriana, conifers Pinus cf. rigios, P. cf. hepios, Calocedrus suleticensis, Tetraclinis salicornioides, Torreya bilinica, cf. Cephalotaxus parvifolia and numerous angiosperms, e.g. Liriodendron haueri, Daphnogene cinnamomifolia, Platanus neptuni, Cercidiphyllum crenatum, Sloanea artocarpites, Ulmus pyramidalis, Celtis pirskenbergensis, Carya fragiliformis, C. quadrangula, Betula brongniartii, B. dryadum, Alnus rhenana, A. cf. kefersteinii, Carpinus grandis, Ostrya atlantidis, Acer crenatifolium, A. cf. palaeosaccharinum, A. integrilobum and Craigia bronnii. Several angiosperm foliage specimens of both monocots and dicots have not yet been identified to a particular genus and species. The fossil plant assemblage at Matrý corresponds to two vegetation types, i.e. a zonal riparian forest and zonal mixed mesophytic forest, as corroborated by the Integrated Plant Record vegetation analysis. The vegetation thrived under a humid climate, characterized by average values of MAT (13.4 °C), WMMT (23.8 °C), CMMT (3.6 °C) and MAP (1,117 mm). The Matry fossil flora is similar in composition to the flora of Žichov from the same Oligocene Děčín Formation in the České středohoří Mts.

A recently recovered site of plant macrofossils, Ludvíkovice, in the České středohoří Mts. is situated on Sokolí vrch hill, belonging to the Děčín Formation (radiometrically dated to 30.8–24.7 Ma), according to regional stratigraphy. The flora has yielded a fern, Rumohra recentior, and several angiosperms, but no conifers. The prevailing foliage is preserved without cuticles. Noteworthy are records of Daphnogene cinnamomifolia, Laurophyllum cf. acutimontanum, Platanus neptuni, Sloanea artocarpites, Carya fragiliformis / C. quadrangula, Alnus rhenana, Trigonobalanopsis rhamnoides, Eotrigonobalanus furcinervis and cf. Quercus sp. Several foliage specimens of dicots could not be identified to species level, i.e., Leguminophyllum sp., Pungiphyllum cf. cruciatum and Dicotylophyllum sp. div. The fossil plant assemblage of Ludvíkovice corresponds to zonal mesophytic vegetation accompanied by riparian elements. This is corroborated by the Integrated Plant Record vegetation analysis, which reconstructs a zonal broad-leaved evergreen forest similar to the living broad-leaved evergreen sclerophyllous forest from Southern Hunan and Northern Guangxi in SE China. The vegetation thrived under a humid climate characterized by average values of MAT (14.6–24.1 °C), WMMT (24.7–28.3 °C), CMMT (2.2–18.8 °C) and MAP (979–1724 mm). The fossil flora of Ludvíkovice is similar in composition to the floras of Markvartice, Veselíčko, also from the Oligocene Děčín Formation of the České středohoří Mts. and the Hrazený hill.

Palaeofloras of the Paleogene in Serbia are relatively rare, especially in comparison with floras from Neogene sediments. Most Paleogene phytoassociations from the territory of Serbia existed in a dry and warm climate. The youngest Paleogene phytoassociation originates from the Pranjani Basin (Western Serbia), locality Kamenica. The age of this palaeoflora is determined as Late Oligocene. This fossil plant assemblage is different from other Paleogene phytoassociations. The palaeoflora from Kamenica is characterized with leaf imprints larger than in other Paleogene fossil floras. Furthermore, it differs in taxonomical composition. The prevailing forms are conifers and representatives of broad-leaved evergreen forests. In other Paleogene phytoassociations, elements of broad-leaved evergreen forests are extremely rare. The dominating elements in the palaeoflora of Kamenica are the conifers, especially Glyptostrobus, Pinus, Sequoia and Tetraclinis. The representatives of the broad-leaved evergreen forests are Laurus, Magnolia, ?Quercus?, etc.

The Middle Eocene flora of Csordakút (N Hungary)The Middle Eocene fossil plant assemblage from Csordakút (N Hungary) comprises plant remains preserved exclusively as impressions. Algae are represented by abundant remains of Characeae, including both vegetative fragments and gyrogonites. Remains of angiosperms comprise Lauraceae (Daphnogenesp.), Fagaceae (cf.Eotrigonobalanus furcinervis), Ulmaceae (Cedrelospermumdiv. sp.), Myricaceae (Myricasp.,Comptoniadiv. sp.), Leguminosae (leaves and fruit), Rhamnaceae (?Zizyphus zizyphoides), Elaeocarpaceae (Sloanea nimrodi, Sloaneasp. fruit), Smilacaceae (Smilaxdiv. sp.). The absence of gymnosperms is indicative of a floristic similarity to the coeval floras of Tatabánya (N Hungary) and Girbou in Romania.Sloanea nimrodi(Ettingshausen) Kvaček & Hably, a new element for the Hungarian fossil record indicates a floristic relation to the Late Eocene flora of Kučlin (Bohemia).

A new permineralized fossil plant assemblage is described from volcaniclastic tuff collected in the Upper Permian (Wuchiapigian to Changhsingian) Xuanwei Formation at Shanjiaoshu mine, Guizhou Province, China. The assemblage is fragmentary but contains a small sphenopsid strobilus, a partial strobilus of a lepidodendralean lycopsid, pinnae of the filicalean fern Anachoropteris and a filicalean non-laminate fertile pinna rachis, the marattialean ferns Eoangiopteris, Scolecopteris and Psaronius, hooked stems of probable gigantopterid affinity, and two kinds of cardiocarpalean ovules. This represents the first indisputable evidence of Anachoropteris from the Permian of China, and contrasts with previous evidence from Europe and North America that indicates this genus became extinct during earliest Permian times. The assemblage highlights the persistence of plants from wetland communities and mire ecosystems into the Upper Permian of southern China, and adds further support to the presence of the Ameriosinian phytogeographical realm. This represents the first record of a plant assemblage preserved in volcaniclastic sediments from the Upper Permian of southern China, and in combination with other recently discovered plant assemblages in similar deposits in southern China, suggests volcanism to be an important factor in facilitating permineralized plant preservation in this realm. Although the source of the volcanism that produced the tuff is unknown, its age and location are consistent with the Emishan Large Igneous Province (LIP) of southwest China.

Abstract The middle Eocene (Lutetian) fossil plant assemblage from Tatabánya (N Hungary) comprises plant remains preserved mostly as impressions. Remains of angiosperms are represented by Lauraceae (Laurophyllum div. sp., Daphnogene Unger), Rhamnaceae (Ziziphus Miller), Malvaceae s.l. (Byttneriopsis Z.Kvaček et Wilde), Leguminosae, and Palmae, and the occurrence of other families, i.e., Dioscoreaceae, Myrtaceae, Fagaceae, Anacardiaceae, Berberidaceae, Juglandaceae, and Theaceae, is uncertain. The scarcity of gymnosperms is a character similar to the coeval floras of Csordakút (N Hungary) and Girbou in Romania. The presence of Ziziphus ziziphoides (Unger) Weyland, high number of linear shaped leaves with entire margin and coriaceous texture (Lauraceae vel Fagaceae), and small-leaved Leguminosae suggests a “subhumid” character of the vegetation, which is recognisable also in early Palaeogene floras of eastern Central and Southeastern Europe, e.g., the Tard Clay floras in Hungary and floras of Serbia/Macedonia. In contrast, the Eocene floras from Central/Western Europe are indicative of a generally non-xerophytic character, e.g., Staré Sedlo in Bohemia, Messel, Geiseltal, and the Weisselster Basin floras in Germany. A frost-free climate with high mean annual temperatures similar to that estimated for coeval European floras may also be inferred for the Tatabánya flora.
