Although this plant is listed as a species (either Senecio kleiniiformis or Senecio kleiniaeformis) on many websites and nursery plant lists, these names are not listed as botanical names or synonyms by taxonomic sources. According to the Encyclopedia of Succulents, "This plant is of controversial origin, possibly a cultigen (i.e. a plant of commerce that has been selected by humans and used in horticulture), and does not have any naturally occurring populations though closely related Senecio occur in South Africa."
