A floral formula is a system of representing the structure of a flower using specific letters, numbers and symbols. It represents floral symmetry, number of parts, connation and adnation, insertion, and ovary position. Floral formulas are useful tools for remembering characteristics of the various angiosperm families. Their construction requires careful observation of individual flowers and of variation among the flowers of the same or different individuals.
A floral formula consists of five symbols indicating from left to right:
- Floral Symmetry

Some important points to be remembered while writing floral formulae:
