1 Kiwifruit flowers have both male and female reproductive organs on each flower. However, they are functionally imperfect. Pollen on "female" flowers is sterile and the ovules on "male" flowers are non-functional.
2 Occasionally olive flowers have stamens with abortive pistils.
3 Some cultivars are predominantly monoecious while others are predominantly dioecious.
4 Variable among cultivars.
