• This type of placentation is found in peas.

✓ Free central placentation

• In free central placentation, the ovules develop on the central axis while the septa are absent.

• This type of placentation is found inDianthus and primrose.

✓ Basal placentation

• The ovary in which the placenta develops from its base and a single ovule is found attached to the base is said to have basal placentation.

• It is found in marigold and sunflower.

✓Parietal placentation

• When the ovules develop on the inner walls of the ovary, the ovary is said to have parietal placentation.
