In the process of plant evolution the corolla developed from modified stamens that had lost their anthers or (more rarely) from top leaves. The endless variety of corollas in shape, detail of structure, color, and the like is a valuable aid in the taxonomy of plants.


Collectively, the petals of a flower.
