Placentation is the arrangement of a placenta or placentae in the ovary of a flower. In sunflower, basal placentation is seen. The ovary is unilocular and bears a single placenta at a base with generally a single ovule. Other examples include Marigold and Ranunculus.

50, 50
50, 100
50, 2500
2500, 2500
