Acradenia euodiiformis is a small- to medium-sized tree growing in north eastern New South Wales, Australia. The Bonewood or Yellow Satinheart is an understorey tree, found naturally from Bulahdelah (32° S) to the McPherson Range (28° S) bordering with the state of Queensland.


The Bonewood is often seen in rainforests as an understorey tree. Particularly on poorer sedimentary soils and along creeks. Sometimes found growing on the more fertile basaltic soils and at relatively high altitudes.


Acradenia euodiiformis usually grows from 12 to 20 metres tall and a stem diameter of up to 60 cm.

The trunk is rarely cylindrical. Usually irregular in shape, sometimes with several stems. The bark is creamy, usually smooth, somewhat corky with vertical lines of pustules. The outer surface of live bark is in patterns of red and cream.

Leaves are opposite and usually in threes. (Occasionally in fives or twos). Leaflets not toothed, and somewhat oblique at the base. Flowers appear from October to December, being white and scented in panicles.

The fruit matures from January to March, being two hard carpels, 6 to 10 mm long. Seed germination is difficult.
