TL;DR: In this paper , a global database of orchid reproductive biology is presented, which contains more than 2900 species representing all orchid sub-families and 23 of 24 tribes, with information on habit, breeding systems, means of pollinator attraction and the identity of pollinators.

TL;DR: In this paper , the authors used ITS sequencing and relative genome size estimation to explore the evolutionary origin of Euphorbia subgenus Esula and found that polyploidization is a key factor in the diversification of flowering plants, but appears to be of only minor importance in the evolution of E. section Esula.

TL;DR: The European fan palm (Chamaerops humilis, Arecaceae) is the only native palm in continental Europe, providing ecosystem services that are hard to obtain from other species as mentioned in this paper .

TL;DR: In this article , the authors studied the population genetic structure of the heather Erica mackayana in Ireland and northern Spain and compared it with its widespread close relative Erica tetralix using single nucleotide polymorphisms (SNPs).

TL;DR: In this paper , the authors used a modified restriction site associated (RAD) DNA-sequencing approach along with ITS and plastid DNA sequence data for reconstructing and dating the phylogeny of the Calcarata species complex of Viola section Melanium.

TL;DR: In this article , the anatomical characters of leaflets of representatives of Discolobium and Riedeliella in terms of their diagnostic value at the genus and species levels and to provide information about the type, location and histochemistry of their secretory structures, and their usefulness for the systematics of the genera.

TL;DR: In this article , the authors used a phylogenomic approach to study the genetic structure of Deschampsia cespitosa in Europe and how the polyploid cytotypes/subspecies are related to the diploids.

TL;DR: In this paper , the authors present a protocol for characterizing the full diversity of capitula from any lineage of Asteraceae, which involves making a whole dissection of a capitulum from fresh material; it is simple and cost-effective and requires relatively easy-to-transport equipment.

TL;DR: In this article , the authors presented new molecular, morphological and palynological data and reinterpret previous results, demonstrating that the species should be classified in Distimake instead, reflecting the phylogenetic relationships of the species.

TL;DR: In this paper , the authors used Helianthemum oelandicum subsp. olandicum as a model for studies of mechanisms shaping the diversity in a rapidly radiating lineage of the H. oelandicus aggregate.

TL;DR: In this article , the authors investigated the evolution, taxonomic diversity and morphological disparity of Nitraria throughout the Cenozoic by integrating extant taxa and fossil palynological morphotypes into a unified phylogenetic framework based on both DNA sequences and pollen morphological data.

TL;DR: Zamia katzeriana did not originate from hybridization between Z. splendens and Z. loddigesii as mentioned in this paper , and gene flow and scenarios of demographic history were tested to reveal whether such a hypothesis is confirmed.

TL;DR: In this article , the geniculus, a characteristic equatorial bulge in the exine of the colpus found in many oak species, and test previous hypotheses about the structural basic units in Quercus.

TL;DR: In this article , the authors measured traits in the widespread, unisexual Neotropical tree Virola sebifera (Myristicaceae) across its continental-scale range, and predicted that, given its hyperdominant status, generalist-pollinated flower type, high dispersal capacity and wide ecological amplitude there would be a weak relationship among and within reproductive and vegetative characters with environmental, spatial and biome correlates.

TL;DR: In this paper , the authors examined present and past distributions of Edraianthus taxa by applying ecological niche modelling and found that the extent of range and niche overlap varied among some taxa throughout their evolutionary history, leading to diversification at both allopatric and sympatric levels.

TL;DR: The early-branching clades of Fabaceae subfamily Papilionoideae are characterized by their remarkable lability in floral architecture as mentioned in this paper and are marked by evolutionary conservatism towards strongly bilateral, papilionate flowers.

TL;DR: In this paper , the authors describe the anatomical development of Lepidocaryum tenue, Mauritia flexuosa and Mauritiella armata using standard light microscopy techniques.

TL;DR: In this article , the authors presented the first phylogenetic reconstruction of Ruagea based on two nuclear ribosomal (ITS, ETS) and two plastid DNA regions (rps4trnT, psbA-trnH).

TL;DR: In this article , the authors evaluate intraspecific morphological variation through uni-and multivariate morphometrics and analyse internal transcribed spacer sequences for individuals sampled from 36 sites, including 14 sites where divergent morphotypes occur sympatrically.

TL;DR: In this paper , the authors generate ddRAD-seq data for the highly diverse Vriesea-Stigmatodon lineage to test for correlated trait evolution among pollination syndromes and life form, habitat type, and altitude.

TL;DR: In this article , the authors investigated the condensation patterns (CPs) of prophase chromosomes represent poorly explored and little understood karyotype features of angiosperms with small chromosomes and found that the LCRs correspond to a small hyperacetylated and hypomethylated fraction of the metaphase chromosomes.

TL;DR: The first phylogenomic study using a custom target capture bait panel within the Isonandreae tribe in Sapotaceae is presented in this paper , where a combination of taxon-specific and universal loci from the Angiosperms353 probe set achieved high species resolution within the genus Palaquium and provided the first phylogenomics insights into Malesian representatives of Sapotales, where relationships between taxa often remain poorly understood.

TL;DR: In this paper , the structure and development of flower and inflorescence in Epimedium pubescens and Plagiorhegma dubium were compared with other Berberidaceae to better understand floral evolution within the family.

TL;DR: In this paper , the authors investigated the floral shape, floral pigmentation, and nectar traits in a putative hybrid population, hereafter termed atypical populations (AP) compared to phenotypes of allopatric populations of both species.

TL;DR: In this paper , a trichome taxonomic classification for the genus Croton is proposed, based on well-defined parameters, which can be easily updated as new types are revealed in future surveys.

TL;DR: In this article , the authors present a review of existing information about the formation and composition of cystoliths, their distribution in vascular plants, their relation with anatomy and systematics, and their potential roles in plant tissues.

TL;DR: In this paper , the authors investigated transferred cytoplasmic motifs in green plants including sporebearing plants and seed-bearing plants (hereafter termed spore and seed plants) and found that gene transfer in spore plants was characterized by shorter motifs than that of seed plants.

TL;DR: In this article , leaves and capsules from 11 populations of Rhododendron myrtifolium from the Carpathians were compared with those from 13 populations of R. ferrugineum from the Alps, Pyrenees and Sudetes.
