Olearia cassiniae is a species of flowering plant in the family Asteraceae and is endemic to the south-west of Western Australia. It is an erect or spreading shrub that typically grows to a height of 0.7–1.8 m (2 ft 4 in – 5 ft 11 in) and produces white daisy-like inflorescences, mostly between February and April.[2] The species was first formally described in 1865 by Ferdinand von Mueller who gave it the name Aster cassiniae in Fragmenta Phytographiae Australiae from specimens collected by George Maxwell.[3][4] In 1867, George Bentham changed the name to Olearia cassiniae in Flora Australiensis.[5] The specific epithet (cassiniae) is a reference to the genus Cassinia.[6]
