Plant radiations are a feature of the New Zealand flora and contribute endemic elements to many ecosystems. In this talk I explore what we are learning about the chronology, trait development, ecology and evolution of the modern flora by looking at woody and herbaceous lineages through time. This perspective focuses on distinct lineages and integrates time-calibrated phylogenies with the ecology and distribution of modern species. Immigration, abiotic and biotic selection and geography have all played a role in facilitating species-rich groups, especially after major extinction events and the appearance of new biomes. I will mainly use genera that have come out of the forest into open areas above and below treeline.
