The Floiver 149 



8. Draw (four times natural size) a flower from near the top of 

 your rosebay spike and one from near the bottom. 



9. What are the chief differences in the two rosebay flowers ? 

 After examining the various flowers on your spike write a short 

 sketch of the life of a single flower showing the order in which the 

 different parts open. Is it possible for such a flower to fertilise 

 itself? Give a reason for your answer. 



10. Take one flower from near the top of your head of sage and 

 one from near the bottom. What differences do you see between 

 them ? Touch with your pencil point the lower end of the stamens 

 in the younger flower (the one from the top). What happens ? 

 What will happen to a bee looking for honey in this flower ? Sup- 

 pose it flies next to an older flower where will it settle ? Will the 

 pistil or stamens touch it first? What will happen to any pollen 

 sticking to its back? 



11. Remove the stamens from the younger flower of sage. Draw 

 them (five times natural size) in both positions. 



Remove the pistils from both flowers and draw them (five times 

 natural size). 



12. Out-of-doors. Watch the flowers of dead nettle, pansy, 

 nasturtium, foxglove, honeysuckle, lime, elder, sweet pea, rosebay 

 and sage. Write a list of the insects you see visiting each. 



Provide yourself with a test tube and plug of cotton wool. Catch 

 a bee whilst it is busy on the flowers of the lime. Is there any pollen 

 on the bee, if so, on what part of it ? 



HOME WORK. 



1. Draw any five kinds of flowers each showing one of the devices 

 mentioned in this lesson and say what the device is. 



2. Write a list of any insects you see visiting the flowers of 

 horse-chestnut, lilac, syringa, ivy, holly, pear, lime, plum, or other 

 trees.
