AppearanceAfrican boxthorn is a large shrub which grows up to 5 metres high and is covered in spines.
The leaves are oval in shape and are 10–40 millimetres long and 4–10 millimetres in width.
The solitary flowers emerge from the leaf axils and are purplish.
The species was first formally described in 1854 by British botanist John Miers in the ''Annals and Magazine of Natural History''. His description was based on plant material collected from Uitenhage in South Africa.
