Inflorescence. 



I. Observe the number and position of the main 

 branches. Compare specimens until the normal arrange- 

 ment is clearly understood. 



II. Ascertain the order of development of the flowers. 

 Take a small division of the inflorescence, to avoid confu- 

 sion, and represent it on paper diagrammatically.^ 



III. Classify the inflorescence.^ Does such an arrange- 

 ment of flowers present any physiological advantages ? 



Flower and Fruit. 



I. What is the numerical plan of the flower ? Is this 

 constant in all the specimens ? Is it exhibited in all the 

 whorls ? 



II. Note the relation of the different whorls to each 

 other. Is the ovary superior or inferior ? Where are the 

 stamens attached? 



III. Does the relative position of anthers and stigma 

 favor cross- or self-fertilization, or both ? 



IV. Make transverse sections of a number of immature 

 fruits. Are they all alike ? Draw a section that you con- 

 sider typical. Compare the ripe fruits, if they are to be 

 had, and note the changes that have taken place. Describe 

 and classify the fruit.

 class work, since the indigenous species of Caprifoliacese
