Summary

Floral diagrams are presented for fourteen families out of six orders of the basal groups of angiosperms. The floral diagrams of the basal angiosperms illustrate the early progression of flower diversification. Starting with the most basal angiosperms, different trends in flower evolution are shown through diagrams, illustrating the transition of spiral to whorled trimerous flowers, incipient transformations of floral organs and accessory structures, and the progressive fusion of organs. The major orders are presented with representatives of the most important families and their trends, including Laurales, Magnoliales and Piperales.
