A floral formula is a notation for representing the structure of particular types of flowers. Such notations use numbers, letters and various symbols to convey significant information in a compact form. They may represent the floral form of a particular species, or may be generalized to characterize higher taxa, usually giving ranges of numbers ...
Basic characteristics and significance[edit] A floral diagram is a schematic cross-section through a young flower. [1] It may be also defined as “projection of the flower perpendicular to its axis”. [3] It usually shows the number of floral parts, [Note 2] their sizes, relative positions and fusion.
Typically, the floral formula is used to represent the morphological characteristics of the flowers of a given plant family, rather than of a particular species. The following are the most commonly used symbols: K = calyx; for example, "K5" indicates that the flower has 5 sepals. C = corolla; for example, "C3" means that the flower has 3 petals.
A flower, also known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae).Flowers consist of a combination of vegetative organs – sepals that enclose and protect the developing flower, petals that attract pollinators, and reproductive organs that produce gametophytes, which in flowering plants produce gametes.
Floral symmetry. [Left] Normal Streptocarpus flower ( zygomorphic or mirror-symmetric), and [right] peloric (radially symmetric) flower on the same plant. Floral symmetry describes whether, and how, a flower, in particular its perianth, can be divided into two or more identical or mirror-image parts. Uncommonly, flowers may have no axis of ...
A rose with k = 1 is a circle that lies on the pole with a diameter that lies on the polar axis when r = a cos (θ). The circle is the curve's single petal. (See the circle being formed at the end of the next section.) In Cartesian coordinates, the equivalent cosine and sine specifications are.
The lily family, Liliaceae, consists of about 15 genera and 610 species of flowering plants within the order Liliales. [2] They are monocotyledonous, perennial, herbaceous, often bulbous geophytes. Plants in this family have evolved with a fair amount of morphological diversity despite genetic similarity. Common characteristics include large ...
Its function is to ensure fertilization of the ovule and development of fruit containing seeds. It may arise terminally on a shoot or from the axil of a leaf. [56] The flower-bearing part of the plant is usually sharply distinguished from the leaf-bearing part, and forms a branch-system called an inflorescence .
