Ceratopetalum apetalum, the coachwood, scented satinwood or tarwood, is a medium-sized hardwood tree, straight-growing with smooth, fragrant, greyish bark. It is in the family Cunoniaceae. Coachwood usually grows to a height of 15 to 25 metres, however exceptional specimens can reach 40 metres tall and live for centuries. It is native to eastern Australia in the central and northern coastal rainforests of New South Wales and southern Queensland, where is often found on poorer quality soils in gullies and creeks and often occurs in almost pure stands.
