Just out @ American Journal of Botany Two fossil species of Metrosideros (Myrtaceae) from the Oligo-Miocene Golden Fleece locality in Tasmania, Australia Author(s) Myall Tarran, Peter G. Wilson, Michael K. Macphail, Greg J. Jordan and Robert S. Hill Abstract: PREMISE OF THE STUDY: The capsular-fruited genus Metrosideros (Myrtaceae) is one of the most widely distributed flowering plant genera in the Pacific but is extinct in Australia today. The center of geographic origin for the genus and the reason for

Just out @ American Journal of Botany Widespread paleopolyploidy, gene tree conflict, and recalcitrant relationships among the carnivorous Caryophyllales Author(s) Joseph F. Walker, Ya Yang, Michael J. Moore, Jessica Mikenas, Alfonso Timoneda, Samuel F. Brockington and Stephen A. Smith Abstract: PREMISE OF STUDY: The carnivorous members of the large, hyperdiverse Caryophyllales (e.g., Venus flytrap, sundews, and Nepenthes pitcher plants) represent perhaps the oldest and most diverse lineage of carnivorous plants. However, despite numerous studies seeking to elucidate their evolutionary

Just out @ BMC Evolutionary Biology Phylogenetic and paleobotanical evidence for late Miocene diversification of the Tertiary subtropical lineage of ivies (Hedera L., Araliaceae) Author(s) V. Valcárcel, B. Guzmán, N. G. Medina, P. Vargas and J. Wen Abstract: Background Hedera (ivies) is one of the few temperate genera of the primarily tropical Asian Palmate group of the Araliaceae, which extends its range out of Asia to Europe and the Mediterranean basin. Phylogenetic and phylogeographic results suggested Asia as the center of origin and

Just out @ Revue de Micropaléontologie Taphonomic and palaeovegetational studies in lower Permian (Asselian-Sakmarian) deposits of Chintalapudi Area, Godavari Graben, South India Author(s) Shreya Mishra, Neerja Jha, Sukhbir Singh Gahalain Abstract: Palynomorphs from lower Permian (Asselian-Sakmarian) deposits from Chintalapudi area of Godavari Graben were used to infer palaeovegetation and palaeoenvironments through palynofacies reconstruction and taphonomic studies. The recovered palynofloral assemblage is dominated by Cordaites with subordinate conifers and glossopterids forming the floral canopy. Fillicopsids, equisetopsids,

Just out @ Geobiology Seaweed morphology and ecology during the great animal diversification events of the early Paleozoic: A tale of two floras Author(s) S. T. LoDuca, N. Bykova, M. Wu, S. Xiao, Y. Zhao Abstract: Non-calcified marine macroalgae (“seaweeds”) play a variety of key roles in the modern Earth system, and it is likely that they were also important players in the geological past, particularly during critical transitions such

Just out @ Frontiers in Earth Science Heritability of the Structures and 13C Fractionation in Tomato Leaf Wax Alkanes: A Genetic Model System to Inform Paleoenvironmental Reconstructions Author(s) Amanda L. D. Bender,  Daniel H. Chitwood and  Alexander S. Bradley Abstract: Leaf wax n-alkanes are broadly used to reconstruct paleoenvironmental information. However, the utility of n-alkanes as a paleoenvironmental proxy may be modulated by the extent to which biological as well as environmental factors

The flowers are actinomorphic and structurally bisexual with a single whorl of five fleshy tepals, a single
