Abstract

The name Cotyledon clavifolia Haw., basionym of Adromischus cristatus (Haw.) Lem. var. clavifolius (Haw.) Toelken (Crassulaceae subfam. Kalanchooideae; A. sect. Longipedunculati Poelln.), is lectotypified on a Thomas Duncanson plate held at the Royal Botanic Gardens, Kew. Previous lectotypifications of the name C. clavifolia were not effective. An amplified description is provided for the variety, and it is here recorded from a location northwest of East London.
