TL;DR: The authors reconstructed the ancestral angiosperm flower as a bisexual and radially symmetric, with more than two whorls of three separate perianth organs each (undifferentiated tepals), three separate stamens each and more than five spirally arranged separate carpels.

TL;DR: Genetic similarity underlying the host-parasite interactions appeared to have the most important influence on specialization and host-shifts: generalist multi-host parasite species were found on closely related plant species, and related species in the Microbotryum phylogeny were associated with members of the same host clade.

TL;DR: The evolutionary and ecological context of floral symmetry (adding new data regarding its distribution), as well as the underlying developmental and molecular bases are reviewed, emphasizing symmetry as a model character for understanding the evolutionary bases of homoplastic floral traits.

TL;DR: Maximum likelihood analyses of 2088 aligned nucleotides of plastid and nuclear sequences obtained from up to 185 species of Delphinieae from throughout the geographic range show that three short-lived (facultative annual or biennial) Mediterranean species belonging to Delph inium subgenus Staphisagria are the sister clade to all other DelphInieae, implying that Staph isagria needs to be raised to genus status if Delphineae and

TL;DR: Despite the incompleteness of Stebbins’ original dataset, the analyses highlight major, angiosperm-wide trends in the diversity of flower morphology and demonstrate the power of this previously neglected approach in plant science.
