Note 124 — THE INDIVIDUAL ORGANISM WITH REGARD TO FORM AND METABOLISM (continued 4)

The “ideal whole” is also proved to exist, if any given “Anlage,” say of a branch, is forced to give origin to a root, as has really been observed in certain plants. This case, like many other less extreme cases of what might be called “compensatory heterotypy,” are best to be understood by the aid of the concept of “prospective potency.” It is very misleading to speak of a metamorphosis here. I fully agree with Krašan about this question. See also page 112, note 48, and my Organ. Regul. pp. 77, 78.
