The history of Opuntia Mill. in South Africa is well documented with invasive species of this genus having been controlled for many years. Despite these costly efforts some 12 species (13 taxa) of Opuntia are evidently persisting in a naturalised state and some are emerging as alien invasives. One such species is Opuntia microdasys (Lehm.) Pfeiff., which is already known from the Gauteng, and Western and Eastern Cape provinces. A description of the species in South Africa is provided, along with notes on its areas of occurrence and likely means of spread. A summary of the nomenclature of the genus Opuntia in South Africa is also provided, dating from 1976 to the present.
