Two new Aloe L. species (Xanthorrhoeaceae-Asphodelaceae), section Lomatophyllum Rowley, from Madagascar

Two new taxa from Madagascar, belonging to the section Lomatophyllum Rowley of the genus Aloe L. (Xanthorrhoeaceae, Asphodelaceae), A. maningoryensis J.-P. Castillon, sp. nov. and A. alaotrensis J.-P. Castillon, sp. nov., are described here. The first one is morphologically intermediate between A. occidentalis (H. Perrier) Newton & Rowley from the west coast of Madagascar, and A. orientalis (H. Perrier) Newton & Rowley from the east coast; it grows on the highlands, in the forests near lake Alaotra. The second one, from the same area, is intermediate between A. propagulifera (Rauh) Newton & Rowley and A. socialis (Perrier) Newton & Rowley. Those two new species are particularly interesting because they connect together some morphological groups of Lomatophyllum and thus confirm the unity of the section.
