23. MERISTEME 



Wachstum und Formbildung in den Teilungsgeweben hoherer Pflanzen 



1966 



by O. Schiiepp Birkhauser Verlag 



Experientia Supplementum 1 1 Basel - Stuttgart 



253 pp., 159 figs. Price: S.Fr. 38.— 



This book will be mainly of interest to botanists, particularly experimental 

 plant morphologists. However, it may have some appeal for those zoologists 

 who are interested in the problems of "growth and form" per se, in the 

 tradition of D'Arcy Thompson and others. 



The book presents a very thorough treatment of growth and its morpho- 

 genetic aspects in all the known types of meristems in higher plants. The 

 approach is almost exclusively descriptive, with much emphasis on the 

 mathematical analysis of the cellular and tissular form changes, movements, 

 and forces involved in morphogenesis. Many of the mathematical analyses 

 are theoretical models, and some of them are highly complex. 



The book is profusely illustrated with drawings and diagrams, most of which 

 are original.
