Young Blonde Girl Shows Off On The Red Bed With Petals Leaves

Sometimes botanically different parts have the appearance of petals. In the genus Canna the true petals are tiny while the stamens are large and brightly colored. A number of plants have bracts that resemble petals, for example in Bougainvillea, Cornus florida (flowering dogwood) and members of the Euphorbiaceae family.
Corolla
Corolla is the collective term for petals of a flower taken as a group within the calyx. Alternatively, the corolla may be considered as the inner whorl of the perianth structure. The role of the corolla in plant evolution has been studied extensively since Darwin postulated a theory of the origin of elongated corollae.
