THE APPENDAGES TO PLANTS. 



1. By the appendages to plants, are to be understood, 

 the peculiar organs essential to the vegetable economy of 

 some plants and not to others. 



Thus, for example, the sloe would not be perfect without its thorn, 

 or the vine without its tendril ; and yet these parts are not necessary

2. Under the head of appendages to plants, we shall 

 include the branch, the bulb, the bud, the leaf-stalk, the 

 flower-stalk, the stipule, the floral-leaf, the thorn, the 

 prickle, the tendril, the gland, and the pubescence or hair. 



Although it has not been usual in botanical works to include the 

 branch, bnlb, bud, leaf-stalk, and flower-stalk, as appendages, we 

 have preferred mentioning them here, because they are by no means 

 common to all plants. 



3. The branches are a natural division of the stem, 

 peculiar to most trees and herbs, originating generally in 

 the upper part, and often along the sides. 



In the mode of growth and developement of branches, they exhibit 

 nearly the same appearances as the particular stem from which they 

 issue. 



4. The bulb is a species of gem of a tender and suc-
