TL;DR: Carpels and ovules have been differently interpreted over the past two centuries as mentioned in this paper, and some of these interpretations are highlighted, with particular emphasis on the current situation in living angiosperms.

TL;DR: The geographic and temporal distance separating the island and mainland lineages in phylogenetic/phylogeographic reconstructions are key factors for determining the reliability of these two estimates as proxies of TIC.

TL;DR: It is proposed that the Paranaean Sea influenced the divergence of the main clades and Pleistocene events were probably responsible for the diversification of the most recent clades, providing a new hypothesis for the evolution of bromeliads.

TL;DR: This study identified homoplastic features that are also widespread in asterids, probably related to similar floral functions, such as variable patterns of monosymmetric tubular corollas, two fertile adaxial stamens with basal appendages of variable length and herkogamy.

TL;DR: The principal mechanisms of diversification in Sorbus are residual sexuality in apomicts, production of triploid taxa from diploid–tetraploid crosses and production of BIII hybrids, which is determined by self-(in)compatibility and the interplay between stabilizing apomixis and variation-generating sexuality.

TL;DR: RP and BB were supported by Australian Research Council Discovery Early Career Research Awards (DE15010720 and DE160101313) and the National Landcare Programme through the Wimmera Catchment Management Authority.

TL;DR: The aims of this study were to identify the areas with the most species diversity; detect areas of endemism; and discuss the conservation status of the native Mexican woody bamboos.

TL;DR: On the frequency of northern and mountain genetic variants of widespread species: essential biodiversity information in a warmer world is essential to protect biodiversity in a hotter world.

TL;DR: Recent gene flow between the studied Ficaria taxa is either limited or absent, and the holoploid genome size and AFLP data suggest a hybrid origin of the triploids, thereby making their formation via autopolyploidization in F. calthifolia unlikely.

TL;DR: It seems that this kind of centromere is common in the genus Juncus and may represent the standardCentromere organization for Juncus, and there is no reason to hypothesize that other genera of Juncaceae for which centromeres have not been carefully investigated have holocentric chromosomes.

TL;DR: The analyses suggest that a combination of low and incompatible data signal limits the resolution of relationships among New Zealand populations of L. scoparium, and is consistent with genetic diversity being geographically structured.

TL;DR: Biogeographic analyses revealed that many clades probably originated in Madagascar and dispersed to locations in Africa and the Mascarenes, indicating that Madagascar may have acted as an important source of diversity for the region.

TL;DR: The data helps to corroborate that the campo rupestre is both a cradle (due to low zygotic gene flow, prolonged isolation and consequent differentiation) and a lineage museum ( due to local survival during climate oscillations) and two distinct evolutionarily significant units (ESU) are highlighted.

TL;DR: It is found that the species' integrity is maintained despite interspecific hybridization and introgression that drove the origin of a new lineage in P. exserta in the contact zones.

TL;DR: The well-supported phylogenetic tree obtained from nucleotide sequences of multiple regions of plastid genome gave clear insights into the subfamilial classification of Ebenaceae, supporting inclusion of previously recognized genera such as Cargillia, Gunisanthus, Maba, Macreightia and Tetraclis in Diospyros.

TL;DR: This review allowed us to elucidate anatomical and micromorphological features useful in defining and delimiting lineages but also to highlight some research priorities in Bambusoideae.
