Brabejum stellatifolium.

Botanical name: 

Brabejum stellatifolium Linn. Proteaceae. Wild Chestnut.

South Africa. Thunberg says the Hottentots eat the fruit of this shrub and that it is sometimes used by the country people instead of coffee, the outside rind being taken off and the fruit steeped in water to deprive it of its bitterness; it is then boiled, roasted and ground like coffee.

Sturtevant's Edible Plants of the World, 1919, was edited by U. P. Hedrick.
