A DNA barcode for land plants
TLDR
The 2-locus combination of rbcL+matK will provide a universal framework for the routine use of DNA sequence data to identify specimens and contribute toward the discovery of overlooked species of land plants.
Multiple Multilocus DNA Barcodes from the Plastid Genome Discriminate Plant Species Equally Well
TLDR
Resolution to the contentious debate on plant barcoding should involve increased attention to practical issues related to the ease of sequence recovery, global alignability, and marker redundancy in multilocus plant DNA barc coding systems.

TLDR
A century of research on heterostylous plants has passed since the publication of Charles Darwin's book "The Different Forms of Flowers on Plants of the Same Species" in 1877, and this book offers a detailed account of the subject.

TLDR
The results from experiments with marker genes and floral manipulations provide evidence for the function of herkogamy and dichogamy in reducing self-pollination and promoting pollen dispersal and evidence is presented indicating that increased selfing resulting from changes to floral design, or geitonogsamy in large clones, can act as a stimulus for the evolution of dioecy.
Sexual interference of the floral kind
TLDR
The hypothesis that some floral adaptations usually interpreted as anti-selfing mechanisms may serve an alternative function in reducing mating costs arising from this form of sexual conflict is evaluated.
Are plant species inherently harder to discriminate than animal species using DNA barcoding markers?
TLDR
The results using common metrics demonstrate that the number of species supported as monophyletic using barcoding markers is higher in animals than plants, even after controlling for the amount of parsimony‐informative information per species.
Mating cost of large floral displays in hermaphrodite plants
TLDR
Traditional interpretations of floral design and display are proposed to recognize their roles in reducing geitonogamous pollen discounting, which is observed to predict higher selfing and lower outcrossed siring success for larger inflorescences.
Sexual dimorphism in flowering plants.
TLDR
This review documents a range of sexually dimorphic traits in angiosperm species, discusses their ecological consequences, and details the genetic and evolutionary processes that drive divergence between female and male phenotypes.
