Question

Aestivation of the calyx of hibiscus flower

Answer 1

During the process of aestivation, the calyx of a hibiscus flower typically exhibits valvate aestivation. In valvate aestivation, the sepals of the calyx are arranged in a manner where the margins of each sepal just touch one another without overlapping. This allows the sepals to protect the flower bud inside before it opens up. The calyx may be green or colored, and its aestivation plays a crucial role in protecting the delicate flower bud from damage.
