Note 21 



The chief divisions of the keys are marked by letters: 

 A indicates the character of the plant. 

 B indicates the position of the leaves. 

 C indicates the characteristics of the flowers. 



To use this key, one turns to the correct flower color and 

 selects, in alphabetical order, the lettered headings that apply to 

 the plant in hand. 



Finding, for example, a plant with herbaceous (not woody) 

 stems, alternate leaves whose margins are toothed, and yellow 

 flowers with five petals, we read the lines marked A, and see that 

 it must belong under HERBACEOUS PLANTS. Below this, 

 reading the lines marked B, we soon find, Leaves Alternate, 

 Toothed or Lobed, which describes this feature of the plant. 

 Under this are headings marked C; it can go under only one of 

 these, and in this short section each line is read until one is 

 found that applies to the plant and refers to a page where a 

 fuller description will show whether it has been correctly traced. 



Abbreviations: Ivs. — leaves 

 fls. — flowers 

 fr. — fruit
