has a good sized pistil ; and choose one that has just 

 come into bloom. Now take off its calyx, corolla, 

 and stamens ; and when you have laid bare the pistil, 

 cut open the ovary. You will now be able to see the 

 ovule, or ovules, in it. That part within the ovary to 

 which the ovules are attached is called the placenta * 

 (Fig. IC2 p}, and the way in which the placentas 

 are arranged is called placentation* 



But we will now look about for another flower with 

 a large pistil, and this time choose one from which 

 the corolla has faded away, or, as you would say, one 

 which has gone to seed. And so it has. You cut open 

 its ovary and see what once were ovules, but now 

 are seeds (Fig. 108). I have a little more to tell you 

 about flowers in general, and then I will tell you 

 something about this change of ovules into seeds. 



* From Latin "placenta,'" Greek "plakous" " plax" a flat cake, 

 anything flat. See placentation in the Appendix.
