A) Commellina
B) Zostera
C) Salvia
D) fig
Correct Answer: A
Solution :
Commellina benghaknsis or kankauoa bears aerial; chasmogamous (stigma and anthers exposed to pollinating agents), insect pollinated flowers and underground deistogamous flowers. Cleistogamous flowers are bisexual flowers which never open, i.e., always remain dosed. In such flowers the anthers and stigma lie very dose to each other. When anthers 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.
