During the last forty years, one of the most widespread and conspicuous succulent trees in East and north-east Africa has been referred to as E. candelabrum Kotschy or as E. candelabrum Trémaux ex Kotschy. This name is a later homonym of Euphorbia candelabrum Welw. and consequently it is illegitimate. The species to which the name E. candelabrum Kotschy has been widely applied is shown to be conspecific with Euphorbia ingens E. Mey. ex Boiss., which occurs from southern Ethiopia to subtropical South Africa.
