Plants with ovaries having only one or a few ovules, are generally pollinated by:
Butterflies
Birds
Wind
Bees
As we discussed in
Wind as an Agent of Pollination -
Wind pollination also requires that the pollen grains are light and non-sticky so that they can be transported in wind currents. They often possess well-exposed stamens so that the pollens are easily dispersed into wind currents. Stigma is large and often-feathery to easily trap air-borne pollen grains. They have a single ovule in each ovary and numerous flowers packed into an inflorescence.
- wherein
E.g., corn cob - the tassels are actually the stigma and style which wave in the wind to trap pollen grains.
Wind pollination is generally carried out in plants with a single or very few ovary
