OBSERVATIONS FOR NOTEBOOK 



Pink Lady's-slipper : 



(A) I. In what situations have you found these 



plants growing? 



2. When do they blossom? 



3. Have you ever seen any insects visiting the 



blossoms ? 



4. Why would it be a disadvantage to the plant 



for bees to enter the flower at one of the 

 two holes near the top instead of the larger 

 opening in the middle of the expanded 

 labellum? 



5. Have you found any of last year's fruit pods 



among this year's blossoms? 



6. Why should this be called the Moccasin flower? 



(B) Write an account of the structure of the Pink 



Lady's-slipper, showing how it is adapted to 

 cross-pollination by insects. 



(C) Make a careful drawing of the plant as a whole 



and also of the seed pods, if the latter are 

 available. 



(D) Read the account of the pollination of the Lady's- 



slippers on pages 157 to 166 of Blossom Hosts 

 atid Insect Guests and on pages 82 to 89 of 

 Ten Nezv England Blossotns and their Insect 

 Visitors. 



(E) Copy these lines into your booklet: 



Graceful and tall the slender drooping stem, 



With two broad leaves below, 

 Shapely the flower so lightly poised between, 



And warm her rosy glow. 



Elaine Goodale.
