Final answer:
The nature of ovary in epigynous flowers is superior.
Step-by-step explanation:
The nature of ovary in epigynous flowers is superior. In superior flowers, the ovary is positioned above the other flower parts, as shown in Figure 32.5a, where the lily is an example of a superior flower. This is in contrast to inferior flowers, where the ovary is located beneath other flower parts, as shown in Figure 32.5b with the fuchsia as an example.
