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.
The members of both whorls may differ from each other in shape and color and the flowers are said to be heteroclamydeous, as for example rose (Rose sp., rosaceae). When, on the other hand, the calyx and corolla parts are indistinguishable from each other in shape and color, the flower is called homochlamydeous .
The four whorls near the edge are the widest. The ribs are flat, often narrow, almost all marked at their base by four or five conical denticulations, and at the upper extremity of the body whorl, by four small mucronated tubercles, which appear again upon the whorls of the spire. The coloring of the ribs is of a light gray.
Rhodanthe's name means "rose flower", a composite word made up by the Greek words ῥόδον meaning "rose", [3] and ἄνθος meaning "flower, blossom". [4] Rhodon is the origin the English word rose, and seems to have been borrowed into the Greek language from the East. [5]

Stamen is the Latin word meaning "thread" (originally thread of the warp, in weaving). [8]Filament derives from classical Latin filum, meaning "thread" [8]; Anther derives from French anthère, [9] from classical Latin anthera, meaning "medicine extracted from the flower" [10] [11] in turn from Ancient Greek ἀνθηρά (anthērá), [9] [11] feminine of ἀνθηρός (anthērós) meaning ...
Some flower parts are solitary, while others may form a tight spiral, or whorl, around the flower stem. First, at the base, are those non-reproductive structures involved in protecting the flower when it is still a bud, the sepals , then are those parts that play a role in attracting pollinators and are typically coloured, the petals , which ...
