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.
The corolla extends from the calyx outwards. Within it are housed anatomy such as the corolla tube, anthers, stamen, and stigma. The corolla tube is not separate from the corolla, but identifies the base section (some corollas form lobes at the top, which distinguishes the petals from the corolla tube).
