In botany, a whorl or verticil is a whorled arrangement of leaves, sepals, petals, stamens, or carpels that radiate from a single point and surround or wrap around the stem or stalk. [ 1 ] [ 2 ] A leaf whorl consists of at least three elements; a pair of opposite leaves is not called a whorl.
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 ...
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 receptacle. [11] [2] The four main whorls (starting from the base of the flower or lowest node and working upwards) are the calyx, corolla, androecium, and gynoecium.
Floral sexuality is related to the presence or absence of the reproductive whorls: androecium and gynoecium. Flowers that have both whorls (i.e., will produce both male and female gametes) are said to be perfect, bisexual, monoclinous or, more frequently, hermaphrodites, as is the case with potato flowers (Solanum tuberosum, Solanaceae
In a mature flower, the perianth consists of a calyx and the corolla (petals) it supports. Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the corolla.
Whorls of the same organ are separated by "+". Organ counts within a whorl can be separated by ":", for example when part of the whorl is morphologically different. A range can be given if the number is variable, e.g. when the formula summarizes a taxon. K 3+3 – a calyx with six free sepals, arranged as two separate whorls; A∞ – many stamens
Here, New York floral designer Penny Karvounis brings four landmark novels to life in imaginative arrangements that channel protagonist, place, and the stirring power of literature. Wuthering Heights
A cyclic flower is a flower type formed out of a series of whorls; [1] sets of identical organs attached around the axis at the same point. Most flowers consist of a single whorl of sepals termed a calyx; a single whorl of petals termed a corolla; one or more whorls of stamens (together termed the androecium); and a single whorl of carpels termed the gynoecium.
