Olearia arguta is a species of flowering plant in the family Asteraceae and is endemic to northern Australia. It is an erect, hairy aromatic herb that typically grows to a height of up to and has oblong leaves, sometimes with a few pointed teeth near the end and produces white, blue, purple or pink daisy-like inflorescences.[1] It was first formally described in 1867 by George Bentham from specimens collected on an island in the Gulf of Carpentaria by Robert Brown.[2] The specific epithet (arguta) means "sharply-toothed".[3]
Bentham also described two subspecies and the names are accepted by the Australian Plant Census:
Olearia arguta occurs in the Kimberley region of Western Australia, the Top End of the Northern Territory and in north Queensland.[6] It is listed as "not threatened" by the Department of Biodiversity, Conservation and Attractions, and as of "least concern" under the Northern Territory Territory Parks and Wildlife Conservation Act 1976.
