56 THE SECOND BOOK OF BOTANY. 



When the stipe supports corolla, stamens, and 

 pistil, it is called an aitfhophore (Fig. 73). When it 

 supports only stamens and pistil, it is known as the 

 gonopJiore (Fig. 75, 5) ; the gynophore^ gynobase, or 

 carpophore, when it bears the pistil alone (Fig. 75, c). 



Thalamus The receptacle of the flower, or the part of the 

 peduncle into which the floral organs are inserted. 

 Torus Another name for thalamus. 

 Receptacle (recipio, I receive). 

 Thalamus A bed. 

 Torus A couch. 



EXERCISE XV. 

 Appendages of the Receptacle. 



Examine the receptacle in the magnified flowers 

 upon charts 1, 2, 3, and 4. 



Carefully observe the space between the calyx and 

 ovary in the figures opposite. You see a sort of fleshy 

 cushion at the base of the ovary in one case, at the 

 base of the style in another. The raised rim around 

 the pistil is called a disk. It takes on very different 

 shapes in different plants. In Figs. 76 and 77 it is 

 merely a raised cushion ; in Fig. 78 it is seen partly 

 enclosing the ovary. 



In Figs. 79 and 80 the disk is seen surrounding 

 the ovary, while in Figs. 81 and 82 it is shown above 

 the ovary, and at the base of the style.
