Abstract

RESUME Deux nouveaux taxons appartenant a la section Lomatophyllum Rowley du genre Aloe L. (Xanthorrhoeaceae, Asphodelaceae), et en provenance de Madagascar, A. maningoryensis J.-P. Castillon, sp. nov., et A. alaotrensis J.-P. Castillon, sp. nov., sont decrits ici. Le premier de ces taxons est morphologiquement intermediaire entre A. occidentalis (H. Perrier) Newton & Rowley de la cote ouest malgache et A. orientalis (H. Perrier) Newton & Rowley de la cote est ; il pousse sur les hauts-plateaux, dans les forets bordant le lac Alaotra. Le deuxieme taxon, originaire de la meme region, est quant a lui morphologiquement intermediaire entre A. propagulifera (Rauh) Newton & Rowley et A. socialis (Perrier) Newton & Rowley. Ces deux especes sont particulierement interessantes car elles relient plusieurs groupes de Lomatophyllum qu'on pouvait croire eloignes et confirment ainsi l'unite de la section.
