TL;DR: Chloroplastic DNA variation at five microsatellite motifs, two insertion-deletion sites, and eight nucleotide substitution sites was investigated in the Olea europaea complex and polymorphisms serve to distinguish most of the cytoplasmic haplotypes previously recognized.

TL;DR: The personate flower, particularly when occluded, displays one of the most specialized corollas in pollinator exclusion by physical barriers, and is interpreted as the ability of bees of visiting any type of flowers.

TL;DR: It is shown that floral variation can be driven by shifts between pollinators that have been traditionally included in a single functional group, and the consequences of such transitions for plant species differentiation during rapid radiations are discussed.

TL;DR: A new framework for the definition of bipolar disjunctions is proposed and a list of guiding principles to consider how to study bipolar species are reformulated, finding a predominant north-to-south direction of dispersal.

TL;DR: Morphological data provide evidence for the separation of Erodium macrophyllum Hook.
