The embryology of the Papilionaceae is full of interest. In this family, so well characterized by the structure of its flower and fruit, the degree of homogeneity is apparently so great that the systematists hesitates in setting the limits of the various genera within the family. However, from the embryogenic point of view these genera can be as clearly distinguished as those of the Papaveraceae. The Papilionaceae has long been an object for embryological studies on account of considerable variation that exist in the mode of embryonal development so much so that even two different Megarchtypes may occur in the same species as is reported by Rau (1954) in Desmodium laevigatum (Hedysareae), Goursat (1969) in Astragalus glycyphyllos (Astragaleae) and Baptisia austrlis (Podalyrieae).
