petaloidy
Petaloidy is a botanical term used to describe petal-like tissue in flowers, typically arising when non-petal floral organs assume petal characteristics in form, texture, or appearance. It is most evident when stamens or staminodes become petaloid, producing flower parts that resemble petals. In some lineages, sepals or other organs can also become petaloid, leading to flowers with a petal-rich look while the underlying floral architecture differs from that of a typical ray.
Developmentally, petaloidy results from changes in the identity and differentiation of floral organs during growth. Alterations
Petaloidy is a common feature in many ornamental plants, contributing to the elaborate forms of double flowers.
