Tags: Flower
The outer perianth of a flower. The calyx surrounds the corolla, and is typically divided into lobes called sepals. These are frequently green, and reduced relative to the petals, but they can also be large, and brightly colored, resembling petals. In many flowers, the sepals enclose and protect the flower bud prior to opening. Often attract insects with their color or may contain osmophores which are scent structures both of which facilitate pollination.
