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 ...
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 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.
The flowering stems are held well above the foliage and are much branched, and the flowers are loosely arranged into 4 to 6 flowered whorls. [3] The purple, violet to deep blue, or rarely white corolla is up to 50 mm long and 15 mm wide at the throat, and the tube is somewhat curved. [ 2 ]
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 ...
The Four Gentlemen are a recurring theme in art because of their long history as symbols of traditional Chinese virtues, such as uprightness, purity, humility, and perseverance despite harsh conditions.

[4] The flower heads are on the short shoots or at the tip of the long shoots, medium-sized, seated or on up to 10 cm (3.9 in) long stalks. The involucre is 6–8 mm (0.24–0.31 in) in diameter, and consists of three to four whorls of bracts. These bracts are overlapping, lance-shaped, hairless, tawny to greenish in colour with the tip often ...
