| Abstract: | Although New Zealand separated from Gondwana during the late Cretaceous (80 million years ago) it shares strong floristic affinities with other Southern Hemisphere landmasses. For 150 years, biogeographers have debated whether these similarities reflect the ancient Gondwanan connection or subsequent dispersal events. Molecular phylogenies are providing new insights into the history of Southern Hemisphere plant groups. These studies show that many plant lineages are recent arrivals in New Zealand, diversifying rapidly and then travelling to other Southern Hemisphere landmasses. |
