ROSE FAMILY 95 



5. Have you noticed the odor of these blossoms? 



6. Is there any nectar secreted? 



7. How early do the first berries ripen? 



8. How does the structure of the berry differ 



from that of the currant or the black- 

 berry ? 



9. How do the strawberry plants and fruits grow- 



ing in moist places differ from those grow- 

 ing on dry hillsides? 



10. In what ways may new strawberry plants be 



formed ? 



11. How many new plants do you suppose may 



develop in one season from the runners sent 

 out by one plant? 



12. How does the cultivated strawberry differ 



from the wild one? 



(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 

 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.
