Summary

[edit]
Description

A detailed look at the Yellow Oleander's Pollination strategy. It might proceed roughly as follows:

  1. An insect is attracted by the smell of sweet nectar at the bottom of the flower..
  2. There is a hairy barrier, which is shown from above in the inset. The insect can move through it.
  3. The insect then encounters the stigma and by making contact with it deposits pollen from another flower.
  4. Since the hairs leading to the bottom point down the insect can easily get to the nectary.
  5. Going up though, the downward pointing hairs block the insect's path. However, there are hairless bulges just below the anthers.
  6. Once underneath the stigma, its notches and bulges oblige the insect to exit via one of the anthers - thereby collecting the flower's pollen.
