Othonna sonchifolia L. is an earlier name for Senecio cymbalarifolius L. (Asteraceae: Senecioneae)

Abstract

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: A nomenclatural correction is necessary in Othonna L. and Senecio L. (Asteraceae). Conclusions: Othonna sonchifolia L. is recognised as the earliest name for Senecio cymbalarifolius (L.) Less. and the new combination Senecio sonchifolius (L.) J.C. Manning & Magoswana is provided for the species. Othonna cymbalarifolia is lectotypified and Senecio hastifolius (L.) Less. is reinstated from synonymy as a species distinct from S. sonchifolius.
