The following Moringa species are characterized by a massive, swollen, water-storing trunk. Moringa drouhardii is a conspicuous element of the southern Malagasy dry forest. It grows in scattered stands that can number hundreds of individuals, usually on limestone. I found many young trees in gaps in the dry forest in the southeast of the island. In cultivation, M. drouhardii grows extremely fast, surpassing three meters in its first year.Like other moringas in other parts of the world, Moringa drouhardii is used medicinally.
