"Habitat in Aethiopia." RCN: 2239. Lectotype (Wijnands, Bot. Commelins : 90. 1983): [icon] " Crassula altissima perforata" in Dillenius, Hort. Eltham. 1: 114, t. 96, f. 113. 1732. - Typotype : Herb. Dillenius ( OXF ) . Generitype of Crassula Linnaeus (vide Hitchcock, Prop. Brit. Bot. : 143. 1929). Current name: Crassula perfoliata L. var. perfoliata ( Crassulaceae ). Note: Schonland (in Trans. Roy. Soc. S. Africa 17: 224. 1929) treated material in Herb. Sherard ( OXF ) as the type, as presumably did Toelken (in J. S. African Bot. 38: 71. 1972) (in the Dillenian herbarium). However, this was not studied by Linnaeus and is not original material for the name.
