“…Detailed ontogenetic analyses and comparative assessments of the developmental patterns of flowers among closely related groups designed to elucidate phylogenetic relationships or to evaluate developmental programmes have only been carried out in genera with a higher degree of synorganization and a stable number and arrangement of structural elements.

Among the flowering plants flowers are relatively closed systems of a considerable complexity and therefore more suitable for comparative developmental studies than other organs. They work with a few kinds of structural elements that occur in variable or fixed numbers and are arranged in patterns more or less constrained by developmental conditions. Diversity of floral structure occurs at different levels, with emphasis either on number and arrangement or on synorganization and form of thc structural elements. The first level is shown here with examples of several representatives of the primitive subclasses Magnoliidae and Hamamelididae, the second with Asclepiadaceae representing the most advanced subclass of dicotyledons Asteridae. Although early ontogenetic patterns are fairly constant among larger groups, especially the sequence of initiation and position of the different classes of structural elements, there is no strict stability in any of the parameters studied.

Initiation of floral primordia begins in Agalinis densiflora with production of two lateral adaxial calyx lobe primordia followed by a midadaxial primordium, and then primordia of two abaxial calyx lobes. Initiation of three abaxial corolla lobe primordia is succeeded by that of two stamen pairs and then by primordia of two adaxial corolla lobes. The primordium of the abaxial carpel appears before the adaxial one. Except for the calyx, initiation of primordia proceeds unidirectionally from the abaxial to the adaxial side of the floral apex. Zygomorphy in the calyx, corolla, and androecium is evident during initiation of primordia and is accentuated during organogenesis. The calyx undergoes comparatively rapid organogenesis, but the inner three floral series undergo a protracted period of organogenesis. The perianth series reach maturation prior to meiosis in the anthers. Maturation of the androecium and gynoecium are postmeiotic events.
