INDEX OF FAMILIES AND GENERA. 



Tlie numbers refer not to pages but to families and genera. 



It is hoped that the above arrangement will be found more convenient than reference to pages; 

 it will also liave the advantage of indicating in a rough waj- simply by number the place of a given 

 genus or family in the vegetable kingdom. 



The 163 families of flowering plants are described and distinguished on pages 3 to 9 ; the 17 

 families of tlowerless plants on pages 77 and 78. 



The 2255 genera are distinguislied from one another on pages 10 to 76 and 78 to 80. They are 

 described in the body of the work in alpliabetical order. 



For example " ROSACEA, 53," means that the rose family is number 53. The reader will find 

 this family distinguished from all otlier families on page 5, and he will find all the genera of the rose 

 family distinguished from one another on pages 23, 24 and 25. 



Rosa 53 : 46 means that Rose is genus 46 of family 53. It is on page 24.
