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. [note 1]
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.
A range can be given if the number is variable, e.g. when the formula summarizes a taxon. K 3+3 – a calyx with six free sepals, arranged as two separate whorls; A∞ – many stamens; P3–12 – perianth from three to twelve petals; Groups of organs can be described by writing the number of instances in the group as superscript.
This model suggests that class B genes are not only expressed in verticils 2 and 3, but also in 1. It therefore follows that the organs of verticils 1 and 2 express class A and B genes and this is how they have a petaloid structure.
Stamen is the Latin word meaning "thread" (originally thread of the warp, in weaving). [8]Filament derives from classical Latin filum, meaning "thread" [8]; Anther derives from French anthère, [9] from classical Latin anthera, meaning "medicine extracted from the flower" [10] [11] in turn from Ancient Greek ἀνθηρά (anthērá), [9] [11] feminine of ἀνθηρός (anthērós) meaning ...

Stamens are twice as many or equal to the number of petals, inserted at the base of the [4] fleshy ring or cup-shaped disk, and inserted below the pistil(s). [5] Stamen stalks are separate, and anthers are able to move. [4] Flowers have the ovary free, but the petals and stamen are borne on the calyx. [5] In the stamenate flowers, ovaries are ...
Close-up of a Schlumbergera flower, showing part of the gynoecium (specifically the stigma and part of the style) and the stamens that surround it. Plant reproductive morphology is the study of the physical form and structure (the morphology) of those parts of plants directly or indirectly concerned with sexual reproduction.
