TL;DR: A compilation of epiphytic diversity derived from a vast number of sources is presented, meant to be an important tool for studies on the ecology and evolution ofEpiphytes, but also for comparative studies with a focus on other life forms.

TL;DR: High rates of species turnover as inferred from palaeontological and molecular data have been the hallmark of plant evolutionary dynamics in the Neotropics throughout the Cenozoic, with most extant species diversity post-dating the Mid- to Late Miocene.

TL;DR: A molecular phylogenetic study of Acacia s.l and close relatives occurring in Africa was conducted using sequence data from matK/trnK, trnL-trnF and psbA-trNH with the aim of determining the placement of the African species in the new generic system.

TL;DR: Niche conservatism and colonization of adjacent environments seem to have driven speciation in Neotropical Melastomeae, a group of c.

TL;DR: An Eocene/Oligocene onset for the origin of the Madagascan generic endemic flora, with the majority arising in the Miocene or more recently is supported, de-emphasize the importance of the Gondwanan break-up on the evolution of the flora.

TL;DR: A comparison of clades in each family shows success in most clades at dispersing to, and diversifying in, North America and/or the Caribbean, a mix of adaptation to novel ecological zones and niche conservation, and no association between long-distance dispersal and fleshy, animal-dispersed fruits.

TL;DR: The results of this study support the emerging three-way link between herbivory, phenotypic plasticity and epigenetic changes in plants, and contribute to the crystallization of the consensus that epigenetic variation can complement genetic variation as a source of phenotypesic variation in natural plant populations.

TL;DR: It is suggested that ancestors of Gesneriaceae originated in South America during the Late Cretaceous, and that half of the species richness in the northern Andes and Central America originated during the last 10 Myr from a single radiation.

TL;DR: Overall, molecular systematic studies and molecular clocks have demonstrated that there are many more connections between the Neotropics and Palaeotropics, both Asia and Africa, than previously would have been thought under a plate tectonic model.

TL;DR: Recent geological and palaeobiological data suggest an early Oligocene to early Miocene model of evolution of the Isthmus of Panama, consistent with a geologically older age for theIsthmus than previously understood.

TL;DR: The first phylogenetic reconstruction of African and Madagascan species of Solanum subgenus Leptostemonum is presented, with 62 of 76 species native to these areas, plus an additional seven species of largely Asian distribution, using internal transcribed spacer (ITS), waxy and trnT-F regions.

TL;DR: The biogeographical history of Bignonieae is investigated using a tribe-wide time-calibrated phylogenetic tree as a basis for ancestral area reconstructions and four hypotheses for the origin and subsequentBiogeographical spread of the tribe are examined.

TL;DR: The phylogenetic relationships in the genus Tulipa were investigated using DNA sequences from five plastid regions and the internal transcribed spacer region of nuclear ribosomal DNA and the results suggest that section Clusianae should be excluded from subgenus TulipA and accepted at subgeneric rank.

TL;DR: To assess the biogeographical history of this primarily Andean species group and the evolution of different life histories, amplified fragment length polymorphism (AFLP) data were generated for 75 species from throughout the geographical range of the genus.

TL;DR: A phylogenetic framework for revising the classification and character evolution in Cyperus s.s.l. is established and despite the lack of resolution along the backbone of the C4 CyPerus clade and for some internal branches, several well-supported clades can be distinguished.

TL;DR: The rapid radiations of Petunia and Calibrachoa are examples of how strong selective pressures for different pollinators, coupled with adaptation to edaphic and climatic differences, may drive the diversification of plants in the Pampas.

TL;DR: The ancestral distribution of Astrocaryum spp.

TL;DR: The data gathered indicate that barcoding markers may help to identify closely related species clusters and contribute to the inference of major diversification and evolutionary patterns in oaks, but the methodology per se appears to be of limited efficacy in defining species limits, unless a profound revision of traditional Quercus taxonomic categories.

TL;DR: Biogeographical reconstructions suggest that the current distribution patterns may be related to vicariance and a few long-distance dispersal events, and some clades are restricted to narrow geographical areas, perhaps important as a means of conserving evolutionary processes.

TL;DR: DioecY and gynodioecy are demonstrated to be associated with several floral characters, including flower size, number and colour, and Divergence time estimation shows Lepechinia had a mid/late Miocene origin, perhaps as a response to global cooling patterns.

TL;DR: It is suggested that morphological traits used for the delimitation of Thymus spp.

TL;DR: This is the first study to find a similar pattern in a family for which the centre of diversity is in eastern and central Amazonia, and it is found that Chrysobalanaceae most probably originated in the Palaeotropics about 80 Mya.

TL;DR: Phylogenetic relationships among families of Liliales were better defined here than in a previous molecular analysis, although the placement of Corsiaceae with plastid data remains problematic.

TL;DR: The fossil record and molecular clocks calibrated with alternating fossils indicate that the stem lineage of Betulaceae dates back to the Upper Cretaceous, the two subfamilies to the Palaeocene and the most recent common ancestors of each of the living genera to the mid- to late Miocene.

TL;DR: Some differences between populations and species were found in a hierarchical analysis of molecular variance (AMOVA) and in the distribution of the mitochondrial DNA haplotypes, suggesting rather limited gene flow between the taxa and ongoing divergence.

TL;DR: Clade structure in Apocynaceae is now generally well understood, and the principal challenges now lie in identifying characters that can reflect and articulate these clades in a formal classification.

TL;DR: This case study presents a case study on a large set of species-rich palm communities from the western Amazon basin, aimed to elucidate the assembly of these communities by separating the roles of broad-scale biogeographic processes, habitat filtering and intra-habitat processes.

TL;DR: The results clearly signal that the majority of famine and food shortage plants had already been forgotten by the end of the 20th century, but new plants have been introduced as green vegetables for making salads, and the most typical wild food plant of Estonia is a fruit, eaten raw as a snack.

TL;DR: By their stratified organization the nematophytes differ from extant and extinct algae and bryophytes and the enigmatic Spongiophyton, and a complex anatomy and septate tubes suggest affinity with lichenized fungi.

TL;DR: This study provides a first pass at a broad Lantaneae phylogeny, but two important areas remain unresolved: the position of Acantholippia relative to Aloysia; and species-level relationships in the Lantana–Lippia clade.
