THE PARTS OF THE FLOWER 



II 



It will be easy for you to find scores of plants that be- 

 !ong to the immense family of the 

 Grasses. After carefully examining 

 several well-known grasses, like crab 

 grass, examine plants of corn and oats 

 and see how many resemblances to 

 grasses you find in these useful crop 

 plants. These and other grains are 

 grasses (Fig. 10). 



EXERCISE. In every large flower you 

 find, point out (i) the pistil, (2) the stamens, 

 (3) the petals, and (4) the sepals. Find the 

 pollen in all the flowers you examine. Does 

 it show in young flower-buds ? Why is there 

 little or no pollen in flowers that are nearly 

 ready to wither or drop? 



Collect all the cultivated and wild plants 

 that you can find having blossoms shaped like 

 those of the sweet-pea or bean. In your note- 

 book write the names of all these pea-like 

 plants that you know. Leave a long blank 

 space and keep adding to this list all through 

 the season. Examine every kind of plant that 

 you have ever heard called a clover to see 

 blossoms have the shape of a pea or sweet-pea bloom. 



NOTE TO THE TEACHER. Devote as much time as possible to 

 having pupils point out the parts of each flower that may be brought to 

 the class. Have them place in separate piles (i) all the pea-like 

 flowers, (2) all the flowers that seem to them kin to the roses and 

 blackberries, and (3) all the grasses. Probably one or two reviews 

 of this chapter must be given so as to afford time for examination of 

 every flower that is brought in.
