The above keys are simple. Each key is made up of 4 pairs of paragraphs giving distinguishing characteristics. 

 Each pair of paragraphs consists of two alternate statements. The one is followed by the name of a tree and the other 

 by a number. If the name of a tree follows, then it is the tree in question; if a number follows then it directs you to a 

 pair of paragraphs further on in the key preceded by that number. If the characteristics of the tree to be identified do 

 not fit in the first paragraph, then they will correspond to those given in the second paragraph, or else the tree in question 

 does not belong to the group considered in the key.
