Abstract
A fossil capitula and pollen grains of Asteraceae from the Eocene of Patagonia, southern Argentina, exhibit morphological features today recognized in taxa phylogenetically close to the root of the Asteracean tree, such as Mutisioideae and Carduoideae. This fossil supports the hypothesis of a South American origin of Asteraceae and an Eocene age of divergence and suggests that an ancestral stock of Asteraceae may have formed part of a Geoflora developed in southern Gondwana before the establishment of effective dispersal barriers within this landmass.
