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

Australia Country in Oceania

Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the largest country in Oceania and the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. The population of 25 million is highly urbanised and heavily concentrated on the eastern seaboard. Australia's capital is Canberra, and its largest city is Sydney. The country's other major metropolitan areas are Melbourne, Brisbane, Perth and Adelaide.

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 S. lautus . In 1969, the Australian members of S. lautus were recognised as a distinct species, and the name S. pinnatifolius was reinstated. [3]

Achille Richard French botanist

Achille Richard was a French botanist and physician.

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:
