Floral diagram of Anagallis arvensis. [1]: 307 The dot represents the main axis, green structure below is the subtending bract.Calyx (green arcs) consists of five free sepals; corolla (red arcs) consists of five fused petals.
The calyx (the sepals) and the corolla (the petals) are the outer sterile whorls of the flower, which together form the perianth. [17] In some plants, such as Aristolochia , the calyx is the primary whorl, forming a flower up to 20 inches (51 cm) wide, with one sepal growing to a length of 13 feet (4.0 m) – Aristolochia grandiflora , the ...

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.
The floral axis (receptacle) is the circle in the middle, surrounded by staminodes, petals, and sepals. The main axis is the circle at the top of the diagram [2] 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 ...
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.
A diagram showing some kinds of petal or sepal aestivation in flower buds. A: quincuncial; B: twisted, C: cochleate; D: contorted; E: valvate; F: open. Aestivation or estivation is the positional arrangement of the parts of a flower within a flower bud before it has opened.
The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term tepal is appropriate include genera such as Aloe and Tulipa.
