“…Duplication, loss or merging of floral structures, homeotic changes of flower organs, and changes in flower symmetry are among the mechanisms that enabled floral structure to evolve (Becker, Alix, & Damerval, ; Endress, ; Glover, Airoldi, Brockington, Fernández‐Mazuecos, & Martínez‐Pérez, ). Even among taxa that share the same floral bauplan, evolutionary changes in the sizes, shapes, and arrangement of floral structures produced extensive variation in floral morphology (Gardner et al, ; Gómez, Torices, Lorite, Klingenberg, & Perfectti, ; McCarthy et al, ). These changes were accompanied by alterations of floral development, which were reflected in the respective patterns of ontogenetic allometry, the association between size and shape during development.…”
