sepalide

A sepalide is a plant part that is typically leaf-like and green, though it can sometimes be colored, and encloses the developing bud of a flower. Sepals are the outermost whorl of floral organs. Collectively, the sepals of a flower are called the calyx. Their primary function is to protect the inner floral parts, especially the delicate petals and reproductive structures, before the flower opens. In some species, sepals may be modified to perform other functions, such as attracting pollinators or aiding in seed dispersal. For instance, in certain plants, sepals can be brightly colored and resemble petals, a condition known as petaloidy. In other cases, sepals might be reduced or absent altogether. The number of sepals varies among different plant families, but they are often present in multiples of three, five, or seven. Their structure and arrangement are important characteristics used in plant identification and classification.
