 from that of every true Myrtacea, as to leave no doubt of its

EXPLANATION OF THE FIGURES. 



Fig. 1. — a. Section showing the lower series of carpels in the ovary of the 

 Pomegranate many days before the expansion of the flower. 

 b. Section showing the upper series of carpels. These two figures 

 are taken from opposite sides of the same slice. 



Fig. 2. — a. Section showing the lower series of carpels in an ovary some 

 days after the expansion of the flower. At this time consi- 

 derable derangement has taken place, apparently caused by 

 the rapid expansion, in a confined space, of the ovules after 

 impregnation. 



b. Upper series in the same ovary, and, as in the former instance, 

 taken from the opposite sides of the same slice. Here the 

 derangement so obvious in the lower section has not taken 

 place.
