Belongs within: Astereae.

Olearia, tree daisies, is a genus of composite-flowered trees and shrubs found in Australasia (Allan 1961).

Characters (from Allan 1961): Shrubs or trees with alternate or opposite leaves, these mainly tomentose below. Capitula small to large, solitary, or inflorescence variously compound; receptacle alveolate, flat or convex; phyllaries imbricate in several series, margins dry or scarious. Ray-florets, if present, ligulate to filiform, pistillate; disk-florets perfect, tubular. Anther-cells usually acute at base; style-arms of disk-florets flattened, with short obtuse or acute unreceptive tips. Achenes ribbed or striate, usually pubescent to pilose; pappus of unequal barbellate bristles, often slightly thickened at tips.
