MOTHER. 



I HAVE brought in a Daisy, Edward, for you to 

 examine this morning ; and before I tell you any 

 thing of the nineteenth class, Syngenesia, to which 

 it belongs, we will try to find out how the flowers 

 are constructed. [PLATE 21.] At first, you per- 

 ceive, they do not look like any of those that you 

 have already examined. 



EDWARD. 



No, indeed ! There is a sort of cup, and a 

 great many white and pink petals ; but instead of 

 stamens and pistils in the middle, I see only a 

 great number of yellow dots. What are they ?
