Description
Shrub or tree, up to 20 m tall. The outer bark is light brown in colour, smooth, with few to numerous fine lenticels. The Terminalia-like branches occur at irregular intervals. The petioles are kneed at both ends. The leaves are simple, spirally-arranged, often clustered at the ends of branches, leathery, glabrous, and with a toothed margin. The inflorescences are racemose, short, to 4 cm long, with cream or white flowers. The small ovoid fruits are green when young and turn bluish-green when mature. The single seed is enclosed within a hard, sculptured stone which develops from the inner mesocarp. The tree can be easily spotted in the wild as its leaves often turn red when old.
