Imbricate aestivation is found in flowers of 

Imbricate aestivation is observed in the flowers of Gulmohur, where the petals overlap one another in a regular arrangement, but not in a specific order (some may overlap the others, and some may not). This type of aestivation is commonly seen in many members of the Fabaceae family and contributes to the distinctive appearance of their flowers.

On the other hand, the flowers of China rose and lady’s finger exhibit twisted aestivation. In this arrangement, the petals or sepals are arranged in a spiral, with one petal overlapping the next in a continuous twisting pattern. This type of aestivation is typically found in plants like hibiscus (China rose) and okra (lady’s finger), contributing to their characteristic floral structure.

Calotropis, a member of the Asclepiadaceae family, exhibits valvate aestivation. Here, the petals or sepals meet at the edges but do not overlap. The edges simply touch each other, forming a clear boundary, and this arrangement is seen in flowers such as those of Calotropis and other plants in the same family.

Each type of aestivation plays a role in the structure and function of flowers, aiding in pollination and protecting the reproductive organs of the plant.
