Circular sunflower inflorescence with yellow petals and many stamens. Very complexly-shaped white, purple, and green flower. Inflorescence of brown male corn flowers. A group or cluster of flowers is known as inflorescence. The structure and functions of flowersandinflorescences are likely to be understood in any comprehension of plant reproduction and biodiversity. Determinate, single flower in axil of leaf or from basal stem, more than one flower present, main axis bearing flowers directly, more or less flat-topped, outer flowers opening last. Angiosperms dominate our terrestrial ecosystems, and the remarkable flowersandinflorescences have evolved into a spectacular and remarkably diversity. The distinctive reproductive structures of angiosperms, flowersandinflorescences, are of particular interest from both a developmental and evolutionary perspective. Arrow shows a secondary inflorescence not to have had regular flowersand subtended by a cauline leaf. Evolution of flowersandinflorescences 1 13 Fig. Solitary flowers which are not part of an inflorescence are generally actinomorphic (i.e., polysymmetric), as seen in Magnoliaceae, Ranunculaceae, and Rosaceae species. It is shown that centroradialis is expressed in the inflorescence apex a few days after floral induction, and interacts with the floral-meristem-identity gene floricaula to regulate flower position... Three distributions of peloric flowers across an inflorescence are: (1) complete (all flowers peloric, as in the cycloidea mutant of Antirrhinum), (2) scattered (with both peloric and zygomorphic...
