Although the floral structure described above is considered the "typical" structural plan, plant species show a wide variety of modifications from this plan. These modifications have significance in the evolution of flowering plants and are used extensively by botanists to establish relationships among plant species. For example, the two subclasses of flowering plants may be distinguished by the number of floral organs in each whorl: [[dicotyledon]]s typically having 4 or 5 organs (or a multiple of 4 or 5) in each whorl and [[monocotyledon]]s having three or some multiple of three. The number of carpels in a compound pistil may be only two, or otherwise not related to the above generalization for monocots and dicots.
In the majority of species individual flowers have both [[pistil]]s and stamens as described above. These flowers are described by botanists as being ''perfect'', ''bisexual'', or ''[[hermaphrodite]]''. However, in some species of plants the flowers are ''imperfect'' or ''unisexual'': having only either male (stamens) or female (pistil) parts. In the latter case, if an individual plant is either female or male the species is regarded as ''[[Plant sexuality|dioecious]]''. However, where unisexual male and female flowers appear on the same plant, the species is considered ''[[Plant sexuality|monoecious]]''.
Additional discussions on floral modifications from the basic plan are presented in the articles on each of the basic parts of the flower. In those species that have more than one flower on an axis—so-called ''composite flowers''—the collection of flowers is termed an ''[[inflorescence]]''; this term can also refer to the specific arrangements of flowers on a stem. In this regard, care must be exercised in considering what a ‘‘flower’’ is. In botanical terminology, a single [[daisy]] or [[sunflower]] for example, is not a flower but a flower ''[[head (botany)|head]]''—an inflorescence composed of numerous tiny flowers (sometimes called florets). Each of these flowers may be anatomically as described above. Many flowers have a symmetry, if the perianth is bisected through the central axis from any point, symmetrical halves are produced—the flower is called regular or actinomorphic, e.g. rose or trillium. When flowers are bisected and produce only one line that produces symmetrical halves the flower is said to be irregular or zygomorphic. e.g. snapdragon or most orchids.
