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
