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.
Description
[edit]Olearia revoluta is an erect, rounded shrub that typically grows to a height of 0.5–1.2 m (1 ft 8 in – 3 ft 11 in) and has many branches. The leaves are linear to oblong, 6.5–13 mm (0.26–0.51 in) 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.[2][3]
Taxonomy
[edit]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.[3][4] The specific epithet (revoluta) means "revolute", referring to the edges of the leaves.[5]
Distribution and habitat
[edit]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.[2]
Ecology
[edit]The seeds are harvested by the western rosella subspecies Platycercus icterotis icterotis.[6]
