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.
A floral diagram is a graphic representation of the structure of a flower. 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 or can help in understanding angiosperm evolution.
The first authors using them were Cassel [3] (1820) who first devised lists of integers to denote numbers of parts in named whorls; and Martius [4] (1828). Grisebach [ 5 ] (1854) used 4-integer series to represent the 4 whorls of floral parts in his textbook to describe characteristics of floral families, stating numbers of different organs ...

The floral axis (sometimes referred to as the receptacle) is the area of the flower upon which the reproductive organs and other ancillary organs are attached. It is also the point at the center of a floral diagram. Many flowers in division Angiosperma appear on floral axes. The floral axis can differ in form depending on the type of plant.
The disk floret is bisexual with female parts (one pistil containing one style, two stigmas, and an ovary with one ovule) and male parts (stamen, anthers, and filaments). Labeled parts are as follows: 1 – two stigma lobes, shown separated (if fused, the stigma would appear as an extension of the style); 2 – style;
