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 ...
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.
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 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 .

The flower bears six free perianth segments rather than true petals, arranged in two whorls of three, the outer whorl being larger and more convex than the inner whorl. The outer tepals are acute to more or less obtuse , spathulate or oblanceolate to narrowly obovate or linear, shortly clawed, and erect spreading.
The mostly six stamens are set in two whorls: usually the two lateral, outer ones are shorter than the four inner stamens, but very rarely the stamens can all have the same length, and very rarely species have different numbers of stamens such as sixteen to twenty four in Megacarpaea, four in Cardamine hirsuta, and two in Coronopus.
