Morris and Brown, Hansteen,Pfeffer, and numerous others have shown the ability of the embryo(with the scutellum) to digest the starch supplied to it. This has beendemonstrated in numerous ways. The starch has been furnished inthe form of macerated endosperm and in the form of a mixture ofstarch and plaster. In every case, the scutellum was able to corrodethe material supplied and to promote a considerable growth in theplantlet, The embryo is also able to utilize an endosperm which isentirely without living protoplasm. An excised embryo from ahealthy, vital grain can be grafted upon a dead endosperm with perfeet success. Such endosperm may be prepared in any way desired,even by prolonged soaking in absolute alcohol; that is to say, after Bui. 183, U. S. Dept. of Agriculture. Plate
