Species naturalised in southern Africa

List from Plants of Southern Africa - an Online Checklist (SANBI) with some nomenclatural changes and adding in Opuntia monacantha and Opuntia humifusa, which are evidently naturalised in South Africa (Zimmermann et al. 2004). Opuntia vulgaris is removed because according to the Declared List of Invaders, Opuntia monacantha has previously been incorrectly identified as Opuntia vulgaris.
