The aim of this work was to
study the botanical affinity of Mutisiapollis
telleriae. The significance of this morphotype relies on the fact that it
constitutes the first occurrence of the oldest spiny fossil pollen found in Patagonia. Although M. telleriae was originally related to
the subfamily Mutisioideae, the spiny pollen in this tribe is also similar to
those of the subfamily Carduoideae. In this work, the comparison of M. telleriae morphotype with pollen of
its living relatives provided evidences to consider that this morphotype is related
to both subfamilies. This morphotype, along with the exceptional diversity of
fossil pollen of Asteraceae found in Patagonia,
contributes to the knowledge of the early history of the family.
