Achatocarpaceae has been included in Phytolaccaceae by numerous authors (e.g., G. Brown and G. Varadarajan 1985).
Achatocarpaceae is distinguished from Phytolaccaceae by a combination of characters, chiefly unilocular ovaries with a single ovule, unisexual flowers, berrylike fruits, and pollen with obscure pores.
Minute vessel pits, lack of successive cambia, and lack of betalains or anthocyanins are characters further separating Achatocarpaceae from Phytolaccaceae (S. Carlquist 2000).
