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.
