Senecio pinnatifolius is a species of herb native to Australia. Common names include coast groundsel, dune groundsel and variable groundsel.

Description[]

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

Taxonomy[]

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 . 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:

  • (Highland groundsel)
  • (Fineleaf coast groundsel)
  • (Lanceleaf coast groundsel)
  • (Western coast groundsel)
  • (Common coast groundsel)

Distribution and habitat[]

It is native to Australia.
