A revision of the Aloe divaricata Berger group which currently contains three species (with A.deinacantha T.A.McCoy, Rakouth & Lavranos and A. tulearensis T.A.McCoy & Lavranos) is achieved here. The synonymy between A. deinacantha and A. divaricata is shown up, we propose the new combination A. divaricata subsp. tulearensis comb. nov., stat. nov. and rehabilitate the species A. vaotsohy Decorse & Poisson as a subspecies of A. divaricata. At last, the hybrid A. divaricata subsp. vaotsohy x A. helenae Danguy is described here under the name x A. anosyana J.-P. Castillon, hybr. nov.
