Abstract

The interrelationships within the Heliantheae-Ambrosiinae are investigated using cladistic analysis of morphological and cytological data. Twenty-eight species sampled from all genera of the Ambrosiinae are used as terminal taxa. The result reveals that Iva s.l. is polyphyletic. In order to make the different parts of Iva s.l. monophyletic, the following taxa should be recognized: Iva s. str. comprising Iva section Linearbractea and Iva section Iva, Chorisiva, Leuciva, Oxytenia, and Cyclachaena s. str. The two genera Hymenoclea and Xanthium are monophyletic ingroups in a paraphyletic Ambrosia. Therefore, both these genera might be reduced to synonyms under Ambrosia if further investigations using more species as terminal taxa come to the same result.
