TL;DR: The largest eukaryotic genome to date in the monocot Paris japonica (Melanthiaceae, 1C = 152.23 pg), measured using flow cytometry is reported, which is 15% larger than any previous estimate and extends the range of genome sizes to c.

TL;DR: A dated phylogenetic tree based on combined plastid DNA sequences and a comprehensive sample of Poaceae and an additional tree using a supermatrix of morphological and molecular data that included all 800 grass genera so that ancestral biogeography and ecological habitats could be inferred.

TL;DR: It is argued that DNA barcoding using multiple primers (rather than a single pair) is adequate, especially in light of the recent developments in next-generation DNA sequencing.

TL;DR: Analysis of the distributional pattern of the endemics by similarity coefficients offers useful insights into the palaeogeography and biogeography of Greece.

TL;DR: The occurrence of total C4 species, C4 monocots and C4 Chenopodiaceae was assessed for five major phyto-geographical regions of Europe and the abundance was related to the climatic variables of annual mean daily temperature, annual precipitation and DeMartonne's aridity index.

TL;DR: Test the hypothesis that some Early Cretaceous fossils, which share synapomorphies with Ephedra, are members of the extant clade and document morphological, anatomical and histological variation patterns in the female reproductive unit and indicate that some morphological features are evolutionarily informative although intraspecific variation is evident.

TL;DR: The genus Miscanthus s.l. (Poaceae) from China was taxonomically revised and six species, two subspecies and four varieties in this genus were recognized in this report.

TL;DR: A checklist of orchids of Panama and Costa Rica with their d 13 C values and an updated list of all known orchid genera that possess species with the ability to perform CAM are presented.

TL;DR: The internal morphology of the EFNs from species of Fabaceae found in areas of dry-seasonal forest in north-eastern Brazil are described to provide important information for taxonomic and evolutionary studies in the family.

TL;DR: The evolutionary history of the Lindsaeaceae is studied by simultaneously optimizing 55 morphological characters, two plastid genes (rpoC1 and rps4) and three non-coding plASTid intergenic spacers (trnL-F, rps 4-trnS and trnH-psbA) and finding six well-supported and diagnostic clades that can be recognized as genera.

TL;DR: The floral development of two Clematis species and four Anemone species (including Pulsatilla) (Anemoneae, Ranunculaceae) is described.

TL;DR: The genus Pleiochiton, as traditionally circumscribed, comprises nine species of epiphytic shrubs endemic to the Atlantic Rain Forest in eastern Brazil, supported by high jackknife values in all analyses, which showed some resolution if Clidemia blepharodes and C. parasitica were included.

TL;DR: The smooth thick-layered cuticle and dense layers of organelles and starch bodies revealed by preliminary transmission electron microscopy study provide alternative candidates for the primary reflective surface of the speculum; in contrast, the trichomes and conical cells that dominate Ophrys labella occur on the specula of all but the most reflective species, absorb and/or diffuse light.

TL;DR: The karyotype variability observed in the subfamily Epidendroideae suggests that disploidy of one or a few chromosomes has played a decisive role in the establishment of the basic karyotypes.

TL;DR: Findings indicate a gradual, clinal transition from hexaploid to diploid across the elevational and longitudinal gradient and suggest a hybrid zone between the varieties in the Wuling-Xuefeng mountains.

TL;DR: Results of comparative longevity storage experiments at 60% relative humidity and 40 °C suggest seeds from these orchid species are short-lived compared with non-orchid species, and with Australian species in particular.

TL;DR: Relationships between genera of Combretaceae by means of combined analyses of plastid and nuclear sequences are explored and sectional classification within Combretum proposed in earlier morphological studies is confirmed except for the exclusion of C. imberbe.

TL;DR: The phylogeny of the genus Arum is inferred on the basis of four plastid regions, and the evolution of several morphological characters is investigated, suggesting that its centre of origin was the European–Aegean region and that major diversification happened during the last 10 Myr.

TL;DR: In this article, an account of character expression diversity is presented for major wood characters of Caryophyllales, including successive cambia, vessel element perforation plates (non-bordered and bordered, with and without constrictions), lateral wall pitting of vessels (notably pseudoscalariform patterns), vesturing and sculpturing on vessel walls, grouping of vessels, nature of tracheids and fibre-tracheids, storying in libriform fibres, types of axial parenchyma, ray anatomy and shifts in ray

TL;DR: Analysis of AFLPs from populations of Cicerbita alpina through most of its range found a major differentiation between the Pyrenean population and all others, supported by principal coordinate, neighbour joining and STRUCTURE analyses.

TL;DR: An extended molecular phylogenetic analysis of Uvaria (Annonaceae) is presented, using maximum parsimony, maximum likelihood and Bayesian methods, based on sequences of four plastid DNA regions, resulting in six new nomenclatural combinations and two replacement names.

TL;DR: The results suggest that hybridization between the species is rare, but can result in cryptic hybrids morphologically similar to the maternal species.

TL;DR: The lineages of Olea illustrate how low phenotypic differentiation can be also related to a clear molecular differentiation in oceanic island enclaves, probably as a result of oceanic conditions in subtropical environments.

TL;DR: Seed dispersal and population structural patterns are consistent with previous molecular studies, revealing that V. gigantea populations are genetically structured, with low gene flow and a moderate outcrossing rate.

TL;DR: This work provides a new classification of Lepisoroideae by integrating phylogenetic results and known variation of morphological characters and proposed 14 new combinations, among which Caobangia is treated as a synonym of Lemmaphyllum.

TL;DR: Seed micromorphology of the poorly known sections Pneumonanthe, Frigidae and Isomeria is investigated and reveals that seed micronorphology supports the reassignment of some taxa incertae sedis within Gentiana.

TL;DR: Cluster and principal components analyses were performed in order to identify how many taxa exist in this complex and how they can be distinguished morphologically, and results from phenetic analyses support the recognition of five species, one with two varieties.

TL;DR: Pollen tube growth innovations preceded and were essential for the evolution of complete carpel closure, suggesting pollen tube pathways are structurally diverse across Nymphaeales, yet their pollen tubes have similar morphologies and rapid growth rates.
