It grows as an erect herb up to a metre in height, with yellow flowers.[1][2]


The name Senecio pinnatifolius was first published by Achille Richard in 1834, but it was not immediately taken up. Instead, the species was long treated as the Australian component of S. lautus. In 1969, the Australian members of S. lautus were recognised as a distinct species, and the name S. pinnatifolius was reinstated.[3]

The infraspecific taxonomy of the species is complicated and in a state of flux. A number of subspecies and varieties have been published, but these have long been recognised as not accurately reflecting variation within the species. In 2004 a thorough study of the species found ten variants, but did not publish names for them because further nomenclatural work was required for this.[3] The following year a new revision, was published, in which the following varieties were recognised:
