• The light yellow, 3.5 cm-diameter fruit of a South African tree, Scelerocarya birrea, with an intense fragrance and a white fibrous flesh enclosed in a leathery skin with one central stone. The stone contains 2 or 3 kernels (marula nuts) slightly bigger than a peanut and similar in shape to a pine nut. The flesh is a good source of vitamin C and the nut of protein. Not yet marketed commercially.
