Even in absence of pollinating agents seedsetting is assured in :
1 Zostera
2 Salvia
3 Fig
4 Commelina
Explanation:
Cleistogamous flowers are bisexual flowers which never open. In such flowers, the anther and stigma lie very close to each other. When anther dehisce in the flower buds, pollen grains come in contact with the stigma of the same flower i.e, autogamy occurs. So, these flowers produce assured seed set, even in the absence of pollinators.
