OUTLINE STUDY OF SEEDS AND SEEDLINGS. 2l8 



one leaflet. This is shown in part by the joint at the base of the 

 blade, and by the wing-like outgrowths (stiplcs). These out- 

 growths are seen at the base of the blade of each leaflet in the 

 other leaves. The similar outgrowths at the base of the stalk are 

 stipules. Elongation of the lower leaf stalks carries the blade out 

 from under the upper leaves so that it gets better sunlight than 

 it otherwise would. To observe this fact and reason out the 

 meaning is more important than to learn the name of the stalk 

 (petiole). The leaves above the first pair are trifoliate compound 

 leaves. This branching of the blade permits more sunlight to 

 penetrate to the lower leaves. To recognize this fact is more im- 

 portant than to learn that the leaves are pinnately compound. 



This work gives a basis for the study of any other plant in the 

 garden. It shows the kind of facts to look for and question about. 

 All other plants in the school garden will be seen to be modifica- 

 tions, more or less profound, of the bean type.
