MOEPHOLOGY OF EEPBODUCTIVE OEGANS 203 placentation may be best explained on the foliar hypothesis; and that the formation of the free central placenta of the Primulaceae, Santalacese and some other plants, can only be satisfactorily explained by considering the placenta as a pro duction of the axis. In the majority of instances, we find one kind of placenta- tion occurring throughout all the plants of a particular natural order. Thus, the Scrophulariaceae, Ericaceae, and Campanu- laceae present us with axile placentation; the Papaveracese, Violacese, and Crucifers
