Taxonomic and nomenclatural notes on Chilean Senecio (Asteraceae, Senecioneae), including a new particular species

As part of ongoing studies on the genus Senecio in Chile, we here synonymize the name S. phylloleptus with S. reicheanus, as well as S. behnii with the retrieved name S. eriocladus. Furthermore, the original concept of S. coquimbensis is reestablished and its nomenclatural implications detailed. Finally, the identity and presence of S. saxicola in Chile is clarified and the new species S. ephemerus is described.
