Description

A small bushy tree, occasionally reaching 25 metres tall and a trunk diameter of 45 cm. The base of the tree may be flanged or somewhat buttressed in larger trees. The bark is pale, light grey or fawn in colour. Small branches are rusty and hairy.

Leaves simple and alternate, ovate in shape, 7 to 20 cm long. Glossy green above, rusty and hairy underneath. Leaf stalks hairy being 5 to 20 mm long. Leaf veins visible on both upper and lower sides. However, more noticeable below with a covering of brown hairs.

Cream or orange flowers form on short panicles in the months of March to May. Rusty in appearance and with an aniseed scent.

Fruit matures from October to February being a large fleshy drupe, 3 to 6 cm in diameter. Greenish or a deep red in colour. Inside is a single large seed.

Removal of the red fleshy aril is advised to assist germination. Regeneration from fresh seed is very slow, often taking a year for roots and shoots to appear.
