Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
In the 19th century, two contrasting methods of describing the flower were introduced: the textual floral formulae and pictorial floral diagrams. [2] Floral diagrams are credited to A. W. Eichler, whose extensive work Blüthendiagramme [3] [4] (1875, 1878) remains a valuable source of information on floral morphology.
The morphology of a flower, or its form and structure, [10] can be considered in two parts: ... Such diagrams may show important features of flowers, including the ...
One important and unique event in plant morphology of the 21st century was the publication of Kaplan's Principles of Plant Morphology by Donald R. Kaplan, edited by Chelsea D. Specht (2020). [36] It is a well illustrated volume of 1305 pages in a very large format that presents a wealth of morphological data.
Floral formulae are one of the two ways of describing flower structure developed during the 19th century, the other being floral diagrams. [2] The format of floral formulae differs according to the tastes of particular authors and periods, yet they tend to convey the same information. [1] A floral formula is often used along with a floral diagram.

Diagram showing the parts of a mature flower. In this example the perianth is separated into a calyx (sepals) and corolla (petals) A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals.
ABC model of flower development guided by three groups of homeotic genes. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction , a flower.
