In a mature flower, the perianth consists of a calyx (sepals) and the corolla it supports. A sepal (/ ˈ s ɛ p əl, ˈ s iː p əl /) [1] [2] [3] is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom. [4]
Once formed, a bud may remain for some time in a dormant condition, or it may form a shoot immediately. Buds may be specialized to develop flowers or short shoots or may have the potential for general shoot development. The term bud is also used in zoology, where it refers to an outgrowth from the body which can develop into a new individual.
A flower, also known as a bloom or blossom, [1] 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.
These tend to be any species with a small calyx, which is found at the base of the bud and is comprised of small green leaf-like structures—sepals—that protect the flower as it develops.
In typical modern flowers, the outer or enclosing whorl of organs forms sepals, specialised for protection of the flower bud as it develops, while the inner whorl forms petals, which attract pollinators. Tepals formed by similar sepals and petals are common in monocotyledons, particularly the "lilioid monocots".
The outer series (calyx of sepals) is usually green and leaf-like, and functions to protect the rest of the flower, especially the bud. [ 58 ] [ 59 ] The inner series (corolla of petals) is, in general, white or brightly colored, is more delicate in structure, and attracts pollinators by colour, scent , and nectar .
A stipule is considered a "bud scale" if it is hard or scaly and protects leaf buds as they form. These generally fall off as soon as the leaf unfolds. A stipule is considered "tendrillar" if they are long thin tendrils, and are generally used by climbing plants. A stipule is considered "spiny" if they are long and pointy.
