Figure 5 Kanono (Coprosma grandifolia): A New Zealand example of both wind pollination and dioecism. The flowers are male. As is generally the case with wind-pollinated flowers they are small and inconspicuous, but have disproportionately large dangling stamens with large anthers. The hanging stamens move readily with the wind, which shakes out the large quantities of pollen necessary for this rather wasteful method of pollination. The family to which Coprosma belongs, the Rubiaceae, is mostly insect-pollinated with often showy flowers. The species of Coprosma are unusual in the family in being both dioecious and wind-pollinated.
