Floral diagram

Floral diagram is a graphic representation of flower structure. It shows the number of floral organs, their arrangement and fusion, different parts of the flower are represented by their respective symbols. Floral diagrams are useful for flower identification (especially combined with floral formulae), but can also help in understanding angiosperm evolution. They were introduced in the late 19th century and are generally atributed to A. W. Eichler.^[1]
