Medium tree to 15 metres or dense shrub widespread in all types of warmer rainforest; north from Tilba Tilba NSW including Melanesia. Bark exudes a clear sap which turns red. Due to this resin, it will burn when green, unusual for a rainforest tree.

Leaves simple, opposite, elliptic to oblong, thick, tough, both surfaces smooth but ridged slightly by raised venation, green and shiny, paler below, abruptly tapered to a point at the apex, the widest part of the leaf.

Flowers are perfumed, creamy/white, in terminal racemes from August to October. Separate male and female flowers on same plant.

Fruit 12-18 mm capsule green turning brown containing (but not always)3 mottled-brown seeds December to March.

The sap was used by early settlers as a tonic astringent and for staining furniture and marking convicts’ clothing.

Two glands (looking little more than slightly-raised leaf rims) can be seen at the base of the leaves. Characteristic, but not very conspicuous. This photo was taken with a hand lens help up against the camera lens, using the macro setting.
