GLOSSABY OF TEEMS. 



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 Unnecessary 

 to observe, that the differences in the termination of the same word 

 distinguish the gender^ in agreement with that of the generic 

 names.
