Calyx, half inferior. Ovary, half superior. 



NOTE. When the calyx seems to be inserted at the top of 

 the ovary (Fig. 48), you are to regard it as really inserted on 

 the receptacle, but as having its tube grown to the ovary, and 

 so appearing to be inserted at its summit. The words superior

 was understood. The true expression is "calyx adherent to 

 ovary," in place of calyx superior; and "calyx free from 

 ovary," in place of calyx inferior. But the words superior 

 and inferior are in general use, and, being short, are retained 

 in schedule description.
