Morphology of Gymnosperms 
Joun M. CouLTER AND CHARLES J. CHAMBERLAIN 
N 1go1, Coulter and Chamberlain published their ‘Morphology of Gymnosperms,”’ 
which brought together in organized form the results of research up to that time. 
The book was based partly on original work by the authors and partly on material 
from the reports of other investigators, and it at once took its place as the standard work 
on the subject 
e immense increase of knowledge in this - during the last decade has made 
necessary a t thorough revision of the book. This is now presented to the scientific world 
in the belief that it will be no less useful than the ee edition. Each of the seven great 
groups is presented in detail, and a final chapter discusses the problem of phylogeny and 
points out the evolutionary tendency. The presentation is so systematic that no index is 
necessary. The illustrations are numerous and to a great se original. The book is 
intended not only for the use of gphbion nti but for advanced students in the morphology 
of gymnosperms. 70 pages, 462 Pee Sia ah vo, cloth. Postpaid $4.22
