TL;DR: Palaeogeographic reconstructions and the fossil record from the Arabian Peninsula support the plausibility of a hypothesized window of overland dispersal opportunity for lowland tropical forest taxa prior to climate deterioration commencing in the late Middle Miocene, providing an alternative to transoceanic dispersal.

TL;DR: A new genus of the tribe Miliuseae, Hubera, segregrated from Polyalthia and allied to Miliusa, is established and described, characterized by the combination of reticulate tertiary venation of the leaves, axillary inflorescences, a single ovule per ovary and therefore single-seeded monocarps.

TL;DR: Identification keys are provided for all genera currently recognized in Annonaceae and separate keys are presented for the Neotropics, Africa-Madagascar and Asia-Australasia.

TL;DR: The tribal name Bocageeae Endlicher is reestablished and the tribe is circumscribed on the basis of solitary internodal ebracteate pedicels that are articulated at the base, and pollen shed in polyads of eight or more grains.

TL;DR: Maximum parsimony and Bayesian molecular phylogenetic analyses strongly support the close relationship of these three genera to one another as well as to two other African genera, Annickia and Piptostigma, which form a moderately supported clade within the so-called short-branch clade of Annonaceae.
