 and that some plants have likewise peculiar appendages. 



These elementary organs and appendages, as well as their varieties 

 and the parts of which they are composed, are, in some instances, 

 subject to a great diversity of botanical distinction. We will now 

 take an opportunity of considering them in the same order as they 

 were mentioned in the preceding part of the volume. 



NOMENCLATURE OF THE ROOT. 



1. In the Elements of Botany we have described 

 roots as being of six different kinds ; viz. spindle-shaped, 

 truncated, fibrous, ramose, bulbous, and tuberous. 



As these standard variations have been previously explained, we 

 shall not venture any additional remarks. 



2. There are six circumstances from whence botanists 

 have found it necessary to assign expressive terms to
