Description #
The snuff box tree is often only a shrub and reaches a maximum of about 8–13 metres in length. The ovoid leaves grow singly and are thin, hairless and leathery. The large, snow-white, pleasantly-aromatic flowers look similar to roses and have a central mass of yellowish stamens. The roughly spherical fruits are hard and smooth with pointed tips.
The tree is adorned with short, sharp thorns and has fairly smooth bark of a mottled grey. The small fruit is roundish and has a hard shell. Inside is sour, yellowish flesh containing seeds.
Uses & Ecology #
The namesake utility is the making of snuff boxes from the tree’s hard-shelled fruit. The fruits are also used as rattles when the dry seeds are left inside. The fruit pulp can technically be eaten, but it is not great-tasting.
The roots are used in traditional African medicine to treat bladder complaints and dysentery. Oncoba spinosa is also used in traditional Congo medicine as a panacea.
The wood can be used for things like cabinetry and inlay. It is also used for fuel.
