Olearia decurrens, commonly known as the clammy daisy bush,[2] is a species of flowering plant in the family Asteraceae and is endemic to arid, inland Australia.

It is a glabrous, sticky, twiggy shrub with narrow egg-shaped to linear leaves sometimes with toothed edges, and white and yellow, daisy-like inflorescences.

Flowering mainly occurs from February to May and the fruit is a silky-hairy achene about 2 mm (0.079 in) long, the pappus with 35 to 65 bristles in two rows.

[2][3][4][5] This species was first formally described in 1836 Swiss botanist Augustin Pyramus de Candolle who gave it the name Eurybia decurrens in the fifth volume of his Prodromus Systematis Naturalis Regni Vegetabilis, from material collected by Allan Cunningham in the vicinity of the Lachlan River.

[8] The species name decurrens means "decurrent" and refers to the leaf base running down the stem.
