Tylecodon is a genus of succulent plants in the family Crassulaceae. Until the late 1970s all these plants were included in the genus Cotyledon, but in 1978 Dr Helmut Toelken of the South Australian Herbarium split them off into a genus of their own. The new name Tylecodon, was apparently chosen as a syllabic anagram of the earlier name Cotyledon.
