Quick Summary

fruit placentation Figure 14: Evolutionary relationships among some types of placentation.

In botany, axile placentation is a type of placentation where ovules are arranged along the central axis of the ovary. This occurs when carpels, the leaf-like structures that form the female reproductive part of a flower, fold inward. The placenta is the part of the carpel to which the ovules attach. In axile placentation, these placentae are located on a central column within the ovary. Partitions can form from this central column to the ovary wall, creating chambers called locules that separate the placentae and attached ovules. This arrangement is a key characteristic used in plant classification.12
