Cryptocarya erythroxylon is a medium to large rainforest tree, that grows from the Barrington Tops in New South Wales to the Gladstone area in Queensland. The common name is the Pigeonberry Ash, Rose Maple, or Rose Walnut.

This is one of the largest laurels in Australia. Mature specimens usually reach around 35 metres tall, though there is a 57 metre tall tree at Murray Scrub near Kyogle close to the NSW–Queensland border. It grows between 500–1050 m altitude.

The group of Cryptocarya trees are mostly from the tropics or warmer temperate areas. This tree is unusual as it grows in cooler regions, subject to frost and rare snowfall. It's also an unusually tall tree from the Cryptocarya genus.

The trunk is often buttressed, and the grey or white cylindrical trunk is a conspicuous feature in the rainforest. Leaves are 6 to 13 centimetres long, white and veiny underneath. The small cream flowers form in early summer, the fruit is a black drupe maturing in the cooler months. Germination occurs easily after removal of the black aril.
