Senecio cymbalarifolius (L.) Less. is the correct name for S. sonchifolius (L.) J.C.Manning & Magoswana, nom. illeg. and clarification of the name S. sonchifolius (L.) Moench (Asteraceae: Senecioneae)

Background: Ongoing systematic studies in the African flora necessitate periodic nomenclatural adjustments and corrections.Objectives: To effect requisite nomenclatural changes.Method: Relevant literature was surveyed and type material located and examined.Results: The combination Senecio sonchifolius (L.) J.C.Manning & Magoswana (2017), based on Othonna sonchifolia L., is an illegitimate later homonym for S. sonchifolius (L.) Moench (1802).Conclusions: The name Senecio cymbalarifolius (L.) Less. is the earliest legitimate name in Senecio for the taxon previously known as S. sonchifolius (L.) J.C.Manning & Magoswana, nom. illeg. On internal evidence, we conclude that S. sonchifolius (L.) Moench was intended as a combination based on Cacalia sonchifolia L. and that the citation of the basionym as Cineraria sonchifolia L. was an error.
