Abstract
IN the history of angiosperm embryology there have been three distinct periods: the first, in which the chief aim was to unravel the chief facts regarding the development of the pollen and embryo sac, and the processes of fertilization and seed formation; the second, in which interest centred largely round a study of comparative embryology and an evaluation of the data thus obtained for the improvement of the existing systems of classification; and the third and latest in which embryology has become an experimental subject like cytology and physiology, where one tries to study the optimal conditions for the storage of the pollen and its germination; the receptivity of the stigma, fertilization and fruit-setting and how far the normal processes of development can be influenced or altered by a change in the environment.
