          Abstract

          Two new species are added to the narrowly delimited genus Gochnatia . Of these, G. lojaensis sp. nov. represents a northern extension of the genus and tribe into Ecuador and G. recticulifolia sp. nov. occurs in northern Peru. In addition to descriptions for the two new species, a key is provided for all known species in the genus Gochnatia and a pubescence character is noted that clearly separates Gochnatia from Moquiniastrum .

          A fully resolved backbone phylogeny reveals numerous dispersals and explosive diversifications throughout the history of Asteraceae

          Significance Flowering plant species represent at least 95% of all vascular plants on Earth, and members of the sunflower family comprise roughly 10% of this diversity. The family is often considered taxonomically difficult primarily because it is enormous in size and cosmopolitan in distribution. Using phylogenomics, we were able to fully resolve the backbone of the sunflower family tree. We provide evidence for a late Cretaceous origin followed by explosive diversifications and dispersals during the middle Eocene—ultimately resulting in the family’s 25,000+ extant species. Our results provide a framework to interpret the spatiotemporal patterns of migration out of South America and the family’s explosive diversifications out of Africa that led to its global evolutionary and ecological success.
