Box Gordon McPherson, Herbarium, Missouri Botanical Garden, P.O. 299, Louis, Missouri St. 63166, U.S.A. Capuron (1973), in updating the work of Perrier de la Bathie (1953, 1954) on the species of Terminalia found Madagascar, provided a useful discussion of the genus as well in On as a good key to 35 of the species that he recognized. the basis of his study and of an examination of specimens housed have decided that a recent collection from the the at P, I an undescribed southeastern part of the island represents species.
