Ricinocarpos pinifolius, commonly known as wedding bush,[2] is a shrub of the family Euphorbiaceae and is endemic to eastern Australia.

The smooth leaves are narrow, 1–3 mm (0.039–0.118 in) wide, 1–4 cm (0.39–1.57 in) long and the leaf margin may be either rolled downwards or backwards on a petiole about 3 mm (0.12 in) long.

The seed capsule is roughly spherical shaped, about 12 mm (0.47 in) in diameter and thickly covered with spines.

[2][3][4] Ricinocarpos pinifolius was first formally described in 1817 by René Louiche Desfontaines and the description was published in Memoires du Museum d'Histoire Naturelle.

[7]: 466 The wedding bush is found in sandy soils in heath and open forests mostly in coastal locations in New South Wales, Queensland, Victoria, Tasmania and the Northern Territory.
