32. RECENT ADVANCES IN THE EMBRYOLOGY 



OF ANGIOSPERMS 

 1963 



Edit.: P. Maheshwari Internat. Soc. of Plant Morphologists 



467 pp., 1 13 figs. Univ. of Delhi 



This is a collaborative treatise written by 14 contributors. Seven of these 

 work in the Department of Botany, University of Delhi, India, whereas the 

 other seven are from various countries other than India. 



Experimental plant embryology is still in a less advanced state than experi- 

 mental animal embryology. Much of the contents of the book is therefore of 

 a purely descriptive or purely physiological nature. However, at least three of 

 the fourteen chapters may be of interest to animal embryologists, viz. "History 

 and present status of plant embryology" (Maheshwari, India); "Artificial 

 culture of embryos" (Sanders and Ziebur, U.S.A.) and "Plant embryos as 

 reaction systems" (Wardlaw, England). The latter chapter gives a brief 

 synopsis of some essential elements of a future theory of plant embryogenesis, 

 and indicates the types of experiments which will be needed in the near future.

33. LES PROBLEMES DU DeVELOPPEMENT 



DES CARPOPHORES DES AGARICALES 

 ET DE QUELQUES GROUPES VOISINS 

 1963 

 by A. F. M. Reijnders Dr. W. Junk 



467 pp., 2 figs, 55 pis. and 1 table of 76 pp. Den Haag 



Price: $ 17.00 



This monograph is concerned with the morphogenesis of the fruiting bodies 

 of a restricted group of mushrooms (Agaricales, Basidiomycetae). The very 

 thorough work can only be briefly announced here. It is based on the compara- 

 tive study of 234 species. The first half of the book is purely descriptive in 

 content. The second half consists of a discussion of the physiological and 

 phylogenetic principles of development in these organisms. This part also 

 reports on experimental results (influence of external factors, regeneration, 

 transplantation, histochemical determinations). This part is concluded by an 

 extensive English summary. 



The book is illustrated with numerous photomicrographs. It contains a large 

 bibliography and indexes to authors, taxonomic names, and terms.
