DIFFERENT KINDS OF TRUNKS. 



2. Subdivided ; when they are divided into branches irregu- 

 larly or without order : or, 



3. Articulate, jointed; when they are distinguished from 

 space to space, by knots or joints, as in Piper*. 



II. Culmus, a straw, is the proper stem or trunk of a grass, 

 and serves to elevate and support both the leaves and the fructi- 

 fication: it admits of most of the distinctions already given for a 

 caulis or stem ; besides which, it may be either. 



1. Enodis, without knots ; when it is continuous, and not in- 

 tercepted by joints. 



2. Articulate, jointed; when it is connected by various 

 joints. 



3. Sqamose, scaly; when it is covered with imbricate scalesf. 



III. Scapus, a stalk, is an universal trunk, raising the fructifi- 

 cation, but not the leaves, as in NAacissus,...PyROLA,,..CoNVAL- 

 l aria, ...and HyacinthusJ. 



IV. A Peduncle, or foot-stalk ofla flower, is a partial trunk, 

 raising the fructification, but not the leaves. 



Pedicellus, is a partial peduncle. 



The determination of peduncles respects place and manner. 



Determination in respect to place, shows where the base of the 

 peduncle is inserted into the plant : and in this respect pedun- 

 cles are, 



1. Radical, belonging to the root ; when they come out im- 

 mediately from the root. 



2. Cauline, belonging to the stem; when they are placed on 

 the stem. 



3. Rameous, belonging to the branches ; when they come out 

 upon the branches.
