Calyx

The calyx (plural: calyces or calyxes) is the outermost whorl of floral parts, typically composed of sepals. Sepals are modified leaves that enclose and protect the developing bud before it blooms. The calyx provides support to the petals and other reproductive parts once the flower opens. The color, size, and shape of the calyx can vary greatly across different plant species, playing a role in pollination and seed dispersal. The study of the calyx is crucial in plant taxonomy and identification.
