Crassula perfoliata Linnaeus, Species Plantarum 1: 282. 1753.
"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 Tölken (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.
