Phylogeny
Many genera and the whole tribe are in need of revision. Many species currently placed in the genus need to be transferred to other or new genera, and others have been retransferred to Senecio. In its new delimitation the genus is still not monophyletic.[5]
Genera that have been included are the following:[5]
- Aetheolaena
- Culcitum
- Hasteola
- Iocenes B. Nord.
- Lasiocephalus Willd. ex Schltdl.
- Robinsonia
