2. In others, self-pollination occurs, when the caudicles dry the pollen fall on the stigma.  

3. This happens through an external pollinator resulting in a diversity of species.  

4. This is a very special case where the flower attracts the insect to mate with bright petals, odor, and the shape.  

5. These types depend on ants and other insects to get pollinated.

6. Here, the pollens release some kind of force, when an insect gets in contact with anther which results in getting away the agent from the flower.
