Herkogamy is a type of mechanism employed by flowers (angiosperms) to encourage cross pollination over self-pollination. This mechanism involves spatial separation of the stamens and stigma in the flowers. This means that the stamens and the stigma are separated by space so that the stigma cannot get fertilized by the anther.
On the other hand, heterostyly is a form of herkogamy, where the stigma grows at a different length with the anthers such that they cannot get fertilized by them.

Adaptation of Pollination in Calotropis
Calotropis is a genus of flowering plants belonging to the family Apocynaceae. It is adapted to pollination by a unique mechanism known as Herkogamy.
Herkogamy
Herkogamy is a type of pollination adaptation in which the reproductive structures of a flower are positioned in such a way that they are inaccessible to the pollinator. This mechanism is common in plants that are pollinated by insects, as it ensures that the insect comes into contact with the reproductive structures of the flower, thereby facilitating pollination.
In Calotropis, the flowers are large and have a bell-shaped structure. The reproductive structures, i.e., the stamens and the stigma, are located at the base of the flower, and are positioned in such a way that they are not easily accessible to the pollinator.
This ensures that the pollinator has to exert some effort to reach the reproductive structures, and in doing so, comes into contact with the pollen, which is then transferred to other flowers, thereby facilitating pollination.
Conclusion
Thus, the adaptation of pollination found in Calotropis is Herkogamy, which ensures that the reproductive structures of the flower are positioned in such a way that they are not easily accessible to the pollinator, thereby facilitating pollination.
