In 1965, Cornelis Kalkman moved "Pygeum" to "Prunus", and this classification has the authority for now. However, a recent cladistic study notes of "Pygeum": "its relationships to "Prunus" remain to be tested by molecular cladistics." "Prunus africana" is known by the common names African cherry, pygeum (from its former scientific name, "Pygeum africanum"), iron wood, red stinkwood, African plum, African prune, and bitter almond.
