What is the type of placentation in chayote?

The type of placentation in chayote (Sechium edule) is axile.

In axile placentation, the placenta is located at the central axis of the ovary, and the ovules are borne on the inner surface of the ovary wall. This type of placentation is common in many flowering plants, including chayote.

Chayote is a climbing vine that produces edible fruits. The fruits are large, green, and pear-shaped. They have a mild flavour and can be used in a variety of dishes. Chayote is native to Central America and is now grown in many tropical and subtropical regions around the world.
