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.
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.
The following year a new revision, was published, in which the following varieties were recognised:
*
''S. pinnatifolius'' var. ''alpinus'' (Highland groundsel)
*
''S. pinnatifolius'' var. ''capillifolius'' (Fineleaf coast groundsel)
*
''S. pinnatifolius'' var. ''lanceolatus'' (Lanceleaf coast groundsel)
*
''S. pinnatifolius'' var. ''latilobus''
*
''S. pinnatifolius'' var. ''laucocarpus''
*
''S. pinnatifolius'' var. ''maritimus'' (Western coast groundsel)
*
''S. pinnatifolius'' var. ''pinnatifolius'' (Common coast groundsel)
*
''S. pinnatifolius'' var. ''serratus''
