Warionia is a genus in the dandelion tribe within the daisy family. Because Warionia is deviant in many respects from any other Asteraceae, different scholars have placed it hesitantly in the Cardueae, Gundelieae, Mutisieae, but now genetic analysis positions it as the sister group to all other Cichorieae.
The genera Gundelia and Warionia only have disk florets, while all other genera only have ligulate florets.

Remarkable for a member of the tribe Cichorieae are also the disk florets, a trait that is further only present in Warionia saharae.
