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.
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
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 .
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 ...
The first authors using them were Cassel [3] (1820) who first devised lists of integers to denote numbers of parts in named whorls; and Martius [4] (1828). Grisebach [ 5 ] (1854) used 4-integer series to represent the 4 whorls of floral parts in his textbook to describe characteristics of floral families, stating numbers of different organs ...
When it comes to creating beautiful floral arrangements, you can start with your favorite flowers (like fragrant garden roses or statement-making dahlias), coordinate certain colors, or opt for ...
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.
In medieval Europe, the dried plants were used to stuff mattresses, [3] as the coumarin scent of the plants acts as a flea repellant. The flowers were also used to coagulate milk in cheese manufacture (which gives the plant its name, from the Greek word γάλα, gala 'milk') and, in Gloucestershire, to colour the cheese double Gloucester.
