THE EVOLUTION OF SEX IN PLANTS 



By JOHN M. COULTER 



In this work the prevalence of asexual reproduction among plants is emphasized, the author 

 showing that in many of the lower forms sexual reproduction is unknown. Sexual reproduction is 

 described historically as the last method of reproduction attained among plants, and as not replac- 

 ing but as being added to earlier methods. Thus we have variation, and in sex reproduction 

 extreme individuality also. 



The book is written with the author's well-known clearness and effectiveness of style, which 

 brings the subject home to all interested in the general problem of sex evolution, and particularly 

 to those who are interested in plant breeding. The more detailed parts of the discussion arc illus- 

 trated by cuts and drawings introduced into the text.
