Mention various adaptations for wind pollination.

Short/Brief Note

Adaptations in anemophilous flowers:

The flowers are small, inconspicuous, colourless, without nectar and fragrance (odour).
The pollen grains are light in weight, dry and produced in large numbers to increase chances of pollination considering wastage of pollen grains.
Stigma is feathery to trap pollens carried by wind currents.
Stamens are exserted with long filaments and versatile anthers.
Stamens and stigmas are exposed to air currents.
