"Habitat in Africa." RCN: 3682. Type not designated. Original material: none traced. Current name: Mesembryanthemum villosum L. ( Aizoaceae ). Note: Gerbaulet (in Hartmann, Ill. Handb. Succ. Pl., Aizoaceae F-Z : 167. 2001) suggests this may be a species of Aizoon , and it shows the greatest similarity with A. karooicum Compton. The Linnaean name does not appear to be in use and there is no original material extant.
