The branch of the flower that joins the floral parts to the stem is a shaft called the pedicel, which normally dilates at the top to form the receptacle in which the various floral parts are inserted. All spermatophytes ("seed plants") possess flowers as defined here (in a broad sense), but the internal organization of the flower is very ...
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.
Merosity (from the greek "méros," which means "having parts") refers to the number of component parts in a distinct whorl of a plant structure. [1] The term is most commonly used in the context of a flower where it refers to the number of sepals in a whorl of the calyx, the number of petals in a whorl of the corolla, the number of stamens in a whorl of the androecium, or the number of carpels ...

Floral diagramming is a method used to graphically describe a flower. In the context of floral diagramming, the floral axis represents the center point around which the diagram is oriented. [3] The floral axis can also be referred to as the receptacle in floral diagrams or when describing the structure of the flower. [4]
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 ...
Lemma is a phytomorphological term referring to a part of the spikelet. It is the lowermost of two chaff-like bracts enclosing the grass floret.The lemma often bears a long bristle called an awn, and may be similar in form to the glumes, which are chaffy bracts at the base of each spikelet.
A Lilium flower showing the six tepals: the outer three are sepals and the inner three are petals. Undifferentiated tepals are believed to be the ancestral condition in flowering plants . For example, Amborella , which is thought to have separated earliest in the evolution of flowering plants, [ 4 ] has flowers with undifferentiated tepals.
