GLOSSARY 



OF THE 



PRINCIPAL BOTANICAL TERMS USED IN THIS WORK. 



JB=- The reader will bear in mind, that where compound descriptive terms are em- 

 ploved in this work, the last member of the compound word is intended to give the 

 predominant character and that the word or syllable prefixed, merely indicates a 

 modification of that character : as, for example, "ovate-lanceolate " signifies lanceo- 

 late, ~but inclining someichat to ovate; while "lance-ovate' 1 ' 1 means ovate with something 

 of the lanceolate form, <fec. So of colors : " yellowish-green" "bluish-green," &c. signify 

 that green is the prevailing hue, but that it u tinged with a shade of yellow, blue, &c.
