GLOSSARY OF TERMS. 
In addition to most of the terms employed in describing the plants 
in this work, we include the principal specific names; with their 
significations, for the use of those who have not studied Latin. 
Compound words have been omitted in cases where the meaning can 
be ascertained by reference to their component parts. Adjectives 
and nouns of the same derivation, are not always both given, as one 
is usually sufficient to explain the other. It is almost annecessary 
to observe, that the differences in the termination of the same word 
distinguish the gender, in agreement with that of the generic 
hames.
