The name accepted by Australian authorities is Senecio glomeratus, and this is also the name accepted by Plants of the World online. The name Erechtites glomeratus is considered by APNI to be illegal.
It was first described in 1817 by René Louiche Desfontaines as Senecio glomeratus, from a specimen cultivated in the Jardin des Plantes.
