The alpine clematis ( Clematis alpina L., Ranunculaceae) is a liana growing in mountain regions of northern Eurasia. In the European Alpine region, where the subspecies C. alpina subsp. alpina occurs, a few populations are isolated from the main range in the peripheral north-western Prealps, a relatively understudied but biogeographically important region. It has been shown that such edge populations could potentially contain...

Aim Central America is largely covered by hyperdiverse, yet poorly understood, rain forests. Understorey palms are diverse components of these forests, but little is known about their historical assembly. It is not clear when palms in Central America reached present diversity levels and whether most species arrived from neighbouring regions or evolved locally. We addressed these questions using the most species‐rich American p...

Aim The rich flora of the Caribbean islands and surrounding mainland evolved in a context of isolation alternated with phases of terrestrial connectivity between landmasses, climatic fluctuations and episodes of mass extinctions during the Cenozoic. We explored how these events affected the evolution of the sister palm tribes Cryosophileae and Sabaleae, and how continent‐island exchanges, endemic radiations and mass extinction...
