36o GYMXOSPERMS 



Just how far the seedling must develop before it should be called 

 a tree is a matter of individual taste. Farmers use the term "sapling" 

 for stages between the seedling and the tree. The term is convenient, 

 but it makes two points to determine instead of only one. Most bot- 

 anists would call the plant shown in fig. 343 a seedling. It is Pinus 

 pdluslris, is several years old, and all the leaves are on spurs. The 

 plant is about 3 feet in height. 



The anatomy of the seedling has already been considered in chap- 

 ter xi.
