Evidence ispresented supporting the contention that G. nordenskioldi Brown n. comb, is the valid name for Glyptostrobus specimens from the Hooker site of northeastern Arkansas. Numerous specimens of a fossil Glyptostrobus have been The Hooker deposit specimens ofcone-scales are shorter and described from the Hooker site and designated as G. europaeus broader than those of other species.

As the study of these microsporophylls are numerous and scattered through the specimens proceeds, more and more characteristics are found clay-shale of this site, indicating a rapid and general ofandrostrobili, gynostrobili, cone-scales, and seeds which vary disintegration ofboth male and female cones.

Two papers by Brown (1936, 1962) regarding the validity of specific names applied to the genus Glyptostrobus in North In conclusion, the positive identification of Glyptostrobus America have come to the attention ofthe author. Inhis earlier twigs from any fossil site not associated with seeds or work, Brown (1936) assigned the name G. dakotensis to gynostrobili is a very tenuous exercise. Because numerous androstrobili and foliage of Eocene specimens found near seeds, gynostrobili, and androstrobili are associated with Elbowoods, North Dakota, and suggested that all American cupressoid, cryptomeriod, and taxodioid foliage at the Hooker Eocene species of this genus should be included in this taxon. locality, there is no problem as to the generic identity of these • Hebased this recommendation on the followingcharacteristics: specimens.

    Paleocene and Eocene floristic and climatic change in Russia and Northern Kazakhstan MIKHAIL A. AKHMETIEV Paleocene and Eocene floras of Russia and adjacent regions are reviewed with an interpretation of climatic conditions under which they developed. Floristic and climatic changes in western and central regions of Russia in the Paleocene and in the first part of the Eocene were caused by the dynamics and rearrangement of the systems of marine seaways: a longi- tudinal seaway, which connected the Arctic basin with the marginal seas of Northern Peri-Tethys (Turanian, South Rus- sian and others), and a latitudinal seaway, which connected the marginal seas of Northern Peri-Tethys with the Atlantic Ocean. As these systems were progressively reduced, the climate in the middle latitudes changed from paratropical (like in West and Central Europe) to a subtropical monsoon climate with wet summers (Late Ypresian to Lutetian), and later to a climate with wet winters (Late Lutetian to the first part of the Priabonian). Floristic changes reflect these climatic trends. In the Paleogene, cold currents constantly influenced the climate of regions of the northwestern Pacific and facili- tated development of a warm-temperate mesophilic flora. A warmer episode took place in the Early Eocene. At this time thermophilic plants (Sabal, Myrtaceae and Lauraceae) reached Koryakia, North Western Kamchatka, probably as a re- sult of northward migration. Some subtropical plants existed near the Recent Polar circle. The subtropical Raichikha-type Flora lost temperate elements and, by ecological and climatic types, it is more similar to the Recent flora of South-West and South China.

Beijing Institute of Science and Technology Information, Beijing 100048, China 2. Laboratory of Systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, China 3. Institute of Geological Sciences, National Academy of Sciences of Ukraine, Kiev 01601, Ukraine Abstract Mineralized wood collected from Late Pliocene strata near Gorbki village in the Transcarpathian region of Beregovo Kholmogor’e in southwestern Ukraine was anatomically studied and identified. The wood possesses distinctive anatomical features and has distinct growth rings with an abrupt transition from early- to late-wood. Wood consists of tracheids with 1-3 seriate, dominating bi-seriate, opposite pits on the radial walls and taxodioid cross- field pitting, indentures present. Rays are uni-seriate and 1 to 73 cells high. Ray parenchyma horizontal walls thin and smooth. Axial parenchyma distributed in early- and late-wood and is solitary and diffuse, with end walls nearly smooth or slightly nodular. The combination of fea- tures observed in the wood indicates it belongs to the conifer family Taxodiaceae and is most similar to modern Sequoia and assigned to the fossil genus Sequoioxylon. Comparison with species of Sequoioxylon show it is most similar to Sequoioxylon burejense, but ray tracheids were not found in our specimens. We describe the specimens here as Sequoioxylon cf. s. burejense noting this similarity. Extant Sequoia is distributed in the northern California coastal forest eco-region of northern California and southern Oregon in the United States where they usually grow in a unique environment with heavy seasonal precipitation (2500 mm annually), cool coastal air and fog drip.

    ©Naturhistorisches Museum Wien, download unter www.biologiezentrum.at Ann. Naturhist. Mus. Wien 105 A 45–159 Wien, Februar 2004 GEOLOGIE UND PALÄONTOLOGIE The Miocene Flora of Parschlug (Styria, Austria) – Revision and Synthesis By Johanna KOVAR-EDER1, Zlatko KVACEK2 & Margit STRÖBITZER-HERMANN3 (With 5 figures, 11 tables and 15 plates) Manuscript submitted on 23 October 2002, the revised manuscript on 21 January 2003 Abstract The first monographic treatment of the famous fossil flora of Parschlug (Styria, Austria) is presented. It com- prises more than 60 plant species including 4 ferns, 5 conifers, and over 50 angiosperms. Described for the first time are Ulmus parschlugiana and Antholithes stiriacus. Newly combined are Berberis teutonica, B. (?) ambigua, Mahonia (?) aspera, Ternstroemites pereger, Cedrelospermum ulmifolium, Leguminosites hesperidum, L. dionysi, L. palaeogaeus, L. parschlugianus, Prinsepia serra, Cotinus (?) aizoon, and Ailanthus pythii. Diversified mesophytic elements prevail over a few dominant or common azonal woody taxa. Among the for- mer, humid temperate components are relatively scarce and humid subtropical ones are rare, while subhumid, physiognomically sclerophyllous woody taxa are well represented. The age is considered as Karpatian/Early Badenian (late Early/early Middle Miocene) based on the floristic composition. Climatically this association indicates a drier warm-temperate/subtropical regime than documented from earlier and later Miocene times. Keywords: Macroflora, palaeoecology, palaeoclimate, floristic comparison, Miocene, Norian depression, Austria. Zusammenfassung Erstmals wird die Flora von Parschlug (Steiermark, Österreich) monographisch erfasst. Sie enthält mehr als 60 Pflanzenarten, davon 4 Farne, 5 Koniferen und mehr als 50 Angiospermen.

Unter den Waldbäumen Europas spielen die Nadelhölzer keine untergeordnete KoUe, obgleich sie ihrer Mannigfaltigkeit nach ge- genüber den Laubhölzern im Schatten stehen. Was ihnen aber in dieser Beziehung abgeht, ersetzen sie durch die Reichhaltigkeit ihrer Individuen und durch ihr Zusammenleben in geschlossenen Beständen. Auf diese Weise gehen die Nadelhölzer als waldbrin- gende Bäume allen übrigen voran , denn eine Verbreitung , wie sie z. B. die Föhre (Pinus silvestris L.) und die Fichte (Picea excelsa Lk.) in ununterbrochener Ausdehnung über grosse Länderstreckeu zeigen, besitzt kein einziger europäischer Laubholzbaum. Im Ganzen bilden die Coniferen eine sehr umfangreiche und vielfach gegliederte Abtheilung des Gewächsreiches , der man mehr die Bezeichnung einer Classe als die einer Familie beilegen kann, von denen freilich nur ein kleiner Theil auf Europa fällt, die grö- sere Zahl aber auf der ganzen Erde zerstreut wächst, weder die Tropen meidet, noch sich selbst von den äussersten Grenzen des vegetabilischen Lebens ferne hält.

We compiled new and published high-resolution d13C data from across annual growth rings of 33 modern ever- green trees from 10 genera and 15 globally distributed sites to quantify the parameters that affect the observed d13C pattern. Across a broad range of latitude, temperature, and precipitation regimes, we found that the average, measured seasonal 13 13 change in d C(Dd Cmeas, &) within tree rings of evergreen species reflects changes in the carbon isotopic composition of 13 atmospheric carbon dioxide (Dd CCO2) and changes in seasonal precipitation (DP) according to the following equation: 13 13 2 Dd Cmeas = Dd CCO2 – 0.82(DP) + 0.73; R = 0.96. Seasonal changes in temperature, pCO2, and light levels were not found 13 to significantly affect Dd Cmeas. We propose that this relationship can be used to quantify seasonal patterns in paleoprecip- itation from intra-ring profiles of d13C measured from non-permineralized, fossil wood.

Schon hatte ich angefangen das Material zu der folgen­ den Darstellung zu sammeln, als mir die Abhandlung von Th. Beinling: „Ueber die geographische Verbreitung der Coniferen* zu Gesichte kam; da ich aber die Absicht hatte auch die fossilen Arten mit in den Kreis der Betrach­ tung zu ziehen und ausserdem fand, dass sich manches ein­ gehender darstellen liess, als es in dem genannten Werke geschehen war, so verblieb ich bei meinem Vorsatz. Es wird nicht weiter nöthig sein auf das Interesse näher einzugehen, welches die Familie der Coniferen bietet, nur so viel sei bemerkt, dass sie eine derjenigen Familien ist, die bei dem jetzigen Stande der Kenntniss von den Floren der verschiedenen Länder, am ersten die Möglichkeit zu einer genaueren Darstellung ihrer Verbreitung bietet; ich sage nur „am ersten“ denn es bleiben auch bei den Coni­ feren noch sehr viele Arten in den genaueren Verhältnissen ihrer Verbreitung unbekannt. Vielleicht wird es auffallen, dass die angegebenen Zah­ len der Coniferen kleiner sind, als die von Gordon, C a r r i e r e und Beinling angeführten; es rührt dies eines- theils daher, dass die ganz unsicheren Arten nicht mitge­ zählt sind, anderntheils sind viele Arten mit anderen als synonym zusammengestellt worden, — das letztere wird vielleicht von mehreren Seiten nicht gebilligt werden, und es ist daher an den meisten Orten, um die geographische Verbreitung zweier vielleicht doch verschiedener Arten nicht zur Unkenntlichkeit zu verschmelzen, die Verbrei­ tung der einzelnen Synonymen für sich angegeben.

The early Burdigalian (MN3) plant assemblage of the Güvem area (northwestern Central Anatolia) is preserved in lacustrine sediments of the Dereköy pyroclastics. Its age is well constrained by radiometric dates of basaltic rocks bracketing the pyroclastics, making the Güvem flora one of the extremely few precisely dated early Miocene floras in the Mediterranean region. The rich assemblage of impression fossils comprises ferns and fern allies (2 species), gymnosperms (12 spp.) and angiosperms (129 spp.). Ilex miodipyrena sp. nov. is described as a new fossil-species. The most diverse families in the assemblage are the Fagaceae with 12 taxa and the Fabaceae with 12 leaf morphotypes and one fruit taxon. Aquatic plants are represented by seven taxa, riparian (including palms) and swamp forest elements by >35 taxa, and lianas by three taxa (Smilax spp., Chaneya).
