We could term this transformation from stamen to staminode, and to petal, "serial homeosis," but not in th e sense of Takahashi (1994).
Such alternations of trends are clearly very dynamic and are related to several internal (e.g., the degree of sterilization, occurrence of homeosis) or external factors (e.g., pollinator- flower relationships).
The transition of stamens into staminodes, and further into petals is best described by the term "serial homeosis."
The distinctions made between bracteopetals and andropetals by Hiepko (1965) and Takhtajan (1991), or the terms "homeosis"or "heterotopy," as the total or partial replacement of one part by another of the same organism (e.g., Sattler, 1988, 1994; Li & Johnston, 2000) explain the same as the molecular terminology, but they are based on a different point of view.

We will also discuss some of the limitations of heterochrony and suggest an integrative approach incorporating heterochrony, homeosis and heterotopy in plant ontogenetic and phylogenetic studies.
Other developmental mechanisms include homeosis, heterotopy, and homology.
Homeosis refers to a structure, "A," or part of "A," developing at the site of structure "B" (Sattler, 1988, 1994).
The best-known example of homeosis in plants is the replacement of one kind of floral organ by another.
