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.
A geometrical hexafoil. The hexafoil is a design with six-fold dihedral symmetry composed from six vesica piscis lenses arranged radially around a central point, often shown enclosed in a circumference of another six lenses.
Labeled parts are as follows: 1 – corolla (petals) (three petals are joined to form a strap, and in the case of 5 petals, they form a ligule); 2 – style; 3 – two stigma lobes, shown separated (if fused, the stigma would appear as an extension of the style); 4 – reduced calyx (after seed maturity, this forms the pappi);
The morphology of a flower, or its form and structure, [10] can be considered in two parts: the vegetative part, consisting of non-reproductive structures such as petals; and the reproductive or sexual parts. A stereotypical flower is made up of four kinds of structures arranged in whorls around the tip of a short stalk or axis, called a ...
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;

The conspicuous daisy-like flowers are up to 20 millimetres (3 ⁄ 4 in) across, borne in lax corymbs. The outer, ray florets have white ligules and the inner, disc florets are yellow and tubular. It spreads rapidly by seed, and will cover a wide area after a few years. [3] [4] The plant produces achene fruit, and grows in stony slopes and ...
