Leaves are opposite, leathery, shiny dark green to 5cm, tip pointed, base rounded, stalk very short. The flowers are fragrant in pink-white terminal clusters. Each flower is to 2cm and the lobes overlap to the right. The berries are round approx. 1cm and purple-black when ripe.

Edible part(s), preparation methods and palatability
Fruits are edible. The rounded berries, about 1 cm and purple-black when ripe, are consumed raw both unripe and ripe (the fleshy part) by children in normal times and by every hungry people in food shortage periods. The ripe fruits are sweet, although a little bit sour and taste like unripe cherries. The unripe fruits taste tart. They contain 2-4 seeds. Another consumption pattern explained by Bena people is to collect the unripe berries and boil them in hot water and make porridge. The fruits have small seeds inside. Ripe fruits when consumed leave the consumers’ teeth dark red.
