INDEX 



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

 physiological terms, names ot 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, authors' 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 inter- 

 vening pages between the number preceding and that following. — Ed,
