In flowering plants, floral symmetry is a reliable cue for high phenotypic and genotypic fitness: flowers that exhibit greater symmetry tend to be larger and generally produce more nectar than asymmetrical neighbors (Mqller and Eriksson, 1994; Wolfe and Krstolic, 1999; Frey et al., 2005).
Several aspects of interpreting flower structure are relatively straightforward (e.g., counting numbers of parts or determining whether the same types of parts are free from each other or united), but others, such as floral symmetry and gynoecium structure, are more complex.

Arecaceae are supposed to have largely polysymmetric flowers as floral symmetry is not considered in Uhl & Dransfield (1987) and Dransfield & Uhl (1998).
Advancement in our knowledge of floral symmetry will continue to be based on advances in phylogenetic reconstruction, molecular developmental genetics, and function of flowers of different monosymmetry and asymmetry types.
