INDEX 



Note. — This list includes most of the more important topics considered in the book, embracing physio- 

 logical terms, names of substances (even when used only as reagents), and genetic names of plants. Some 

 analysis is attempted for a few topics; spatial limitations preclude more complete analyses. Authors' 

 names are also included, with brief characterizations of the subject considered. Plant names are in Italics, 

 author's names in black-face type. Page numbers are in black-face type, (i) when the topics are chapter 

 or section headings, and (2) when they refer to full citations; where authors are mentioned without complete 

 citations, page numbers are in ordinary type. A dash indicates all intervening pages between the number 

 preceding and that following. — Ed.
