Resumen:
The Late Oligocene Mutisiapollis telleriae,which is the oldest echinate fossil pollen of Asteraceaefrom Patagonia, was tentatively related to the subfamilyMutisioideae. A detailed comparison of M. telleriae withextant asteraceous pollen indicates strong similarities withboth Mutisioideae (in particular the Gongylolepis type) andCarduoideae (some genera of Carduinae) subfamilies. Thismorphotype, as an example of the exceptional diversity offossil pollen of Asteraceae found in Patagonia, contributesto the knowledge of the early history of the family.
