Tylecodon   H. Toelken (1978)
The name Tylecodon originates as an anagram of Cotyledon.

Tylecodon is a genus of around 46 species of small shrubby plants from South Africa and Namibia, which were separated from Cotyledon in 1978. Their deciduous succulent leaves are produced in a spiral arrangement during the winter and flowers produced after the leaves have been shed in the spring or summer. Tylecodon species range from an inch to over 6 feet in height. They are not hardy but the caudiciform habit of many species appeals to many collectors. Many species can be propagated from stem cuttings. The thick stems of Tylecodon paniculata ( Afrikaans: botterboom ) and some other species have attractively peeling bark.
 
Most species are poisonous. Some are grubbed out by South African farmers to protect livestock. T. pearsonii ( syn. Tylecodon luteosquamata ) is said to be sufficiently toxic that it should only be handled while wearing gloves. I haven't experienced any problems from my own plant.
