 shape, and are often not nearly so tree-like as the one

 them when full grown. If you are doubtful whether 

 a particular plant is a tree or shrub, remember that,

 high, is slender, and perhaps has several stems start- 

 ing together at or near the ground, as seen in Fig. 

 262, it is called a SHEUB.
