| − | '''Corolla''' is the overall structure of the [[petal]]s of a flower taken as a group within the [[calyx]]. Normally the corolla is the most conspicuous part of a flower and of a bright colour other than green. The concept of corolla description is widely used in [[botany]] as a primary determinant of [[vascular plant]] identification. 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 [[Charles Darwin|Darwin]] postulated a theory of the origin of elongated corollae.<ref>[http://adsabs.harvard.edu/abs/1988Natur.334..147N Analysis of theory of evolution of corolla elongation involving pollinating species]</ref>
