81. Now we take it for granted that all the organs of the 

 flower have their starting-point or origin at the same one 

 point, namely, at the torus {t^ Fig. 129), hence in this figure 

 of the Golden Currant, it is understood that from t to w the 

 calyx, corolla, stamens, and pistil, adhere together; from it, 

 to -y, the calyx, corolla, and stamens, adhere ; and at -y, all 

 the organs are separate, that is, free. Observe the same 

 structure in the Ear-drop (Fig. 130). 



82. In this and like cases, the calyx is said to be S'uperio7\ 

 because it seems to stand upon the pistil (ovary) and fruit, 

 but the more correct term is, calyx adherent.

 although hard to pronounce, you may as well become ac- 

 quainted with now. When the stamens adhere to the calyx 



81. What do we take for granted ? Please show the adhesions in the
