Acronychia wilcoxiana, commonly known as silver aspen,[2] doughwood, snowwood or mushyberry,[3] is a species of small rainforest tree that is endemic to eastern Australia.

It has simple, elliptical to egg-shaped leaves with the narrower end towards the base, relatively large groups of whitish flowers in leaf axils and broadly oval to more or less spherical, white fruit.

[2][4][5] The silver aspen was first formally described in 1875 by Ferdinand von Mueller, who gave it the name Pleiococca wilcoxiana and published the description in Fragmenta phytographiae Australiae.

[5][8] The species name honours James Fowler Wilcox, a 19th-century collector of birds and plants in northern New South Wales.

[9] Acronychia wilcoxiana grows in rainforest, mostly between Fraser Island in south-east Queensland and Gosford in central-eastern New South Wales and from sea level to an altitude of 450 m (1,480 ft), but a small population of about eight mature trees has been recorded at Primbee in the Illawarra district.
