I now give a key toall the genera of the tribe Stapelier, in “a I 
have taken into consideration all the species known to me, a toa 
those that still remain undescribed. I have retained 7 ere: an 
those groups of species which appear to me to be the — na nthe 
distinct ; and, however diverse seen aeapeem may appear from 
determination of the plants. It will be seen that the genera pao a 
Sarcocodon, previously proposed by myself, and mgr re : 
disappear from the list, as I cannot separate them ae a a 
characters from Caralluma. The stems, however, of Sarcocodo net te 
satisfactorily known, and may afford a distinctive character,
