The Flower 131 



does quite as well as that from the same flower, stamens 

 and pistil sometimes grow separately as in the case of 

 the catkins. When this is the case some arrangement is 

 necessary to ensure that the pollen shall be carried to 

 the pistil. 



PRACTICAL WORK. 



1. Draw exactly 10 times their natural size : 



(a) A flower from the top of your horse-chestnut bunch. 

 (5) A flower from the bottom of it. 



2. Describe as shortly as you can any difference you see between 

 the two flowers. 



3. Take a flower carefully to pieces with a dissecting needle. 

 Are the petals joined together at their base or do they come off 

 separately ? Are the sepals joined at their base ? 



4. Draw exactly five times their natural size : (a) a stamen from 

 a newly opened flower, (6) a stamen from a flower that is beginning 

 to fade. 



5. Are all the stamen heads alike ? What differences do you 

 find ? Are any of them dusty with pollen ? 



6. Draw a pistil exactly five times its natural size. 



7. Have all the flowers pistils ? How do you distinguish the 

 pistil from the stamens? What do you see at the base of the 

 pistil ? 



8. Strip the bunch of its flowers and draw (natural size) the 

 whole stalk with the side stalks growing from it. 



9. Dissect one of each kind of flower given to you, both of the 

 beech and sycamore flowers. Arrange each flower on a separate 

 piece of paper, putting all the sepals in one corner, the petals in 

 another, and so on. Leave them for inspection.
