Description

A small tree reaching 8 metres in height and a trunk diameter of 8 cm. The trunk is usually straight with fairly smooth bark, creamy and green with some brown vertical streaks. Small branches are smooth and slender, green near the leaves.

Leaves are alternate on the stem, not toothed. Lanceolate to reverse ovate in shape, glossy green. 8 to 15 cm long, 2 to 5 cm wide.^[3] A pair of glands occurs on the edge of the leaf, about 5 mm from where the stalk joins the leaf. Leaf stalks 2 to 4 cm long, with a grooved channel on the upper side.

Creamy flowers occur in the months of July to September. Male and female flowers form on separate racemes. The fruit matures from August to October, being a fawn capsule around 2 cm in diameter.
