vated plant all the flowers have become large and sterile.

Suggestions. — 145. If the pupil has been skillfully conducted 

 through this chapter by means of careful study of specimens rather 

 than as a mere memorizing process, he will be in mood to chal- 

 lenge any flower that he sees and to make an effort to understand 

 it. Flowers are endlessly modified in form ; but they can be 

 understood if the pupil looks first for the anthers and ovaries. 

 How may anthers and ovaries always be distinguished? 146. It is 

 excellent practice to find the flowers in plants that are commonly 

 known by name, and to determine the main points in their struc- 

 ture. What are the flowers in Indian corn? pumpkin or squash? 

 celery? cabbage? potato? pea? tomato? okra? cotton? rhubarb? 

 chestnut? wheat? oats? 147. Do all forest trees have flowers? 

 Explain. 148. Name all the moncecious plants you know. 

 Dioecious. 149. What plants do you know that bloom before 

 the leaves appear? Do any bloom after the leaves fall? 150. Ex- 

 plain the flowers of marigold, hyacinth, lettuce, clover, asparagus, 

 garden calla, aster, locust, onion, burdock, lily-of-the-valley, crocus. 

 Golden Glow rudbeckia, cowpea. 151. Define a flower. 



Note to the Teacher. — It cannot be urged too often that 

 the specimens themselves be studied. If this chapter becomes a 

 mere recitation on names and definitions, the exercise will be 

 worse than useless. Properly taught by means of the flowers 

 themselves, the names become merely incidental and a part of 

 the pupil's language, and the subject has hving interest.
