Emmenosperma alphitonioides, the yellow ash or bonewood, is a rainforest tree of eastern Australia.

It grows from Clyde River, New South Wales near Batemans Bay (35° S), to Cape York Peninsula in at the most northerly part of Australia.

White flowers appear between August and November, in cymes of panicles.

When fruiting, the tree is easily identified by masses of orange drupes.

The use of a file is recommended to weaken the seed shell, to assist germination.
