Flowers that are pollinated by the agency of wind have got certain special characters. They are:
i) Flowers are small and inconspicuous.
ii) Flowers are colourless, odourless and nectarless.
iii) They have well-exposed stamens so that pollens are easily dispersed by wind currents.
iv) Large often feathery stigma to easily trap airborne pollen grains.
v) Pollen grains are light, small and winged or dusty.
vi) Pollen grains are dry, smooth, non-sticky and unwettable.
vii) Pollen grains are produced in very large numbers.
