Olearia revoluta is a species of flowering plant in the family Asteraceae and is endemic to the south-west of Western Australia. It is an erect, rounded shrub with linear to oblong leaves with the edges rolled under, and white daisy-like inflorescences.
Olearia revoluta is an erect, rounded shrub that typically grows to a height of and has many branches. The leaves are linear to oblong, long with the edges rolled under, the lower surface woolly-hairy. The heads or daisy-like "flowers" are arranged in leaf axils and are sessile or on a short peduncle with an oval to top-shaped involucre at the base. Each head has 4 to 8 white ray florets surrounding 6 to 10 disc florets. Flowering occurs between May and November.[1]
Olearia revoluta was first described in 1867 by George Bentham in Flora Australiensis from specimens collected by Augustus Oldfield between the Murchison and southern Hutt Rivers.[2] The specific epithet (revoluta) means "revolute", referring to the edges of the leaves.[3]
This olearia grows in sand over sandstone, on the sandplains toward Geraldton and beyond Esperance in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains and Yalgoo bioregions of south-western Western Australia.
The seeds are harvested by the western rosella subspecies Platycercus icterotis icterotis.[4]
