development of plant morphogenesis (with elements of a personal record)". 

 Part three, entitled "Perspectives in plant morphogenesis", is characterized by 

 the author as a "free commentary ... on what I think may be some of the future 

 developments in my subject". In it, he not only enumerates many of the 

 possibilities, but also some of the requirements for further development as he 

 sees them. 



The care devoted by the publishers to the production of the book has resulted 

 in an esthetically highly satisfying volume.
