Analytical methods are now available that can date all nodes in a molecular phylogenetic
tree with one calibration, and which correct for variable rates of DNA substitution in different …

The pantropical flowering plant family Annonaceae is the most species-rich family of
Magnoliales. Despite long-standing interest in the systematics of Annonaceae, no …

This article addresses the challenges involved in estimating the ages of clades using fossils
and DNA sequences. We review the principles and problems of placing fossils in trees of …

Brassicaceae is an important family at both the agronomic and scientific level. The family not
only inlcudes several model species, but it is also becoming an evolutionary model at the …

Annonaceae are a pantropically distributed family found predominantly in rainforests, so
they are megathermal taxa, whereas Rhamnaceae are a cosmopolitan family that tend to be …

Aim Rain forest‐restricted plant families show disjunct distributions between the three major
tropical regions: South America, Africa and Asia. Explaining these disjunctions has become …

Targeted enrichment and sequencing of hundreds of nuclear loci for phylogenetic
reconstruction is becoming an important tool for plant systematics and evolution …

Portulaca is the only genus in Portulacaceae and has ca. 100 species distributed worldwide,
mainly in the tropics and subtropics. Molecular data place the genus as one of the closest …

Aim We test biogeographical hypotheses regarding the origin of Andean‐centred plant
groups by reconstructing phylogeny in the short‐branch clade (SBC) of Annonaceae, and …

Several recent studies have suggested that a substantial portion of today's plant diversity in
the Neotropics has resulted from the dispersal of taxa into that region rather than vicariance …
