Axile placentation

Axile Placentation is a type of placentation found in certain species of flowering plants. It is characterized by the formation of the ovules along the central axis of the ovary, with the septa (walls) of the ovary extending inward from the ovary wall. This type of placentation is commonly found in plants with a superior ovary and a high number of carpels.

Overview

In axile placentation, the ovules are attached to the central column or axis of the ovary. This is in contrast to other types of placentation, such as parietal placentation, where the ovules are attached to the outer wall of the ovary, or basal placentation, where the ovules are attached at the base of the ovary.

The number of carpels in a flower with axile placentation can vary, but it is typically more than two. The carpels are usually fused together, forming a single ovary with multiple chambers or locules. Each locule contains one or more ovules.

Examples

Axile placentation is found in a wide range of flowering plants. Some examples include members of the Rosaceae family, such as apples and pears, and the Solanaceae family, which includes tomatoes and peppers. It is also common in the Ranunculaceae family, which includes buttercups and columbines.
