Kobel, du Pasquier, and Tinsley, 1981, J. Zool., London, 194: 317-322, demonstrated natural hybridization and gene introgression between this species and Xenopus laevis (both with 2n = 36 chromosomes). Evans, Morales, Picker, Kelley, and Melnick, 1997, Mol. Ecol., 6: 333-343, discussed historical structure within this nominal species. See accounts by Picker, 1988, in Branch (ed.), South Afr. Red Data Book, Amph. Rept.: 25-27, Channing, 2001, Amph. Cent. S. Afr.: 241-243, De Villiers, 2004, in Minter et al. (eds.), Atlas Frogs S. Afr.
