5. Have you noticed the odor of these blossoms?

9. How do the strawberry plants and fruits grow- 



ing in moist places differ from those grow- 

 ing on dry hillsides?

11. How many new plants do you suppose may

 out by one plant ? 



12. How does the cultivated strawberry differ

(B) Write a little essay for your wild flower booklet, 

 ', describing the year's history of wild strawberry 



plants. Begin with the winter season when they 

 are covered with snow and tell how, after the 

 snow goes in spring, they send up their blossoms 

 to attract insect visitors ; how these visitors carry 

 the pollen from flower to flower and thus cause 

 the fertilization of the tiny ovules and their de- 

 velopment into seeds; how the part beneath the 

 ^ seed develops into the fruit, which attracts 



W birds to eat it and thus leads to the scattering 



of the seeds in other places ; then how the plant, 

 having ripened its fruit, begins to send out 

 runners in all directions, from which many new 

 plants develop, and finally in autumn takes a 

 rest after the summer's work. 



(C) Illustrate your essay with drawings of the straw- 



berry leaf, blossom, fruit, runner and new plant. 



(D) Read the account of the development of the culti- 



vated strawberry on pages 424 to 452 of The 

 Evolution of Our Native Fruits by L. H. Bailey.
