flower. If it is doubtful under which color the flower 

 falls it may be sought in one, and if not found there, in 

 the other. It will sometimes be found in both. 



Example. — Suppose we find, but cannot identify, 

 the common elder. We first observe that the flower is 

 white, and we turn to the white chart on page 56.

Diagram of a flower. 



Elder {^Samimcus Canadensis) 



We first note under which of the general divisions 

 the plant falls. These general divisions are found on the 

 first page of the chart, thus: 



I. Leaves opposite. 

 II. Leaves whorled. 

 III. Leaves otherwise. 



We observe that the leaves are opposite. We there- 

 fore start with Class I . The first division of Class I is into 



Stems 4-sided. 

 Stems otherwise. 



The stems of our specimen are round. We follow, 

 then, the divisions of "Stems otherwise," namely: 



Trailing or climbing. 

 Upright (-4).
