EXERCISE 76 

 TREE IDENTIFICATION 



Object. To study trees and become familiar with their 

 general form, method of branching, shape and arrangement 

 of leaves, and character of bark. 



Explanation. There are many kinds of trees, present- 

 ing a great variety of shapes and individual character- 

 istics. The form of trees differs; some grow tall and 

 slender, while others are spreading and grow close to the 

 ground. The number of branches and their arrangement 

 vary greatly. The shape, size, and arrangement of 

 leaves are individual characteristics and may be used in 

 distinguishing different kinds of trees. Botanical classifica- 

 tion is based largely upon the method of reproduction, and 

 upon the kind and character of the seed vessels and seed 

 coverings. 



Directions. Go to the city park or a near-by woods and 

 make a list of as many trees growing there as you can identify. 

 Select a typical elm, maple, and ash, and make a drawing of 

 each. The drawing should show the outline form of the tree 

 and the arrangement of the branches. What is the difference 

 in the shape of these trees ? What is the principal difference 

 in the arrangement of the branches?
