"Cyclic flower A cyclic flower is a flower type formed out of a series of whorls; 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. This is a cyclic arrangement. Some flowers contain flower parts with a spiral arrangement. Such flowers are not cyclic. However in the common case of spirally arranged sepals on an otherwise cyclic flower,"
"They measure by and pubescent, hairy outside and sparsely pubescent inside. Collectively forming the outer floral envelope or layer of the perianth enclosing and supporting the developing bud, which is usually green; the sepals, are pale green, narrowly ovate—""oval or egg-shaped""—and 2 to 3 times as long as they are wide, measuring at . They are pubescent, hairy outside and glabrous, smooth without hairs inside. The sepals are acuminate, tapering gradually to a sharp point at the tips of certain leaves or petals or sepals, at their apex. The corolla, a collective term for all the petals of a flower,"
"Petal Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. Together, all of the petals of a flower are called a corolla. Petals are usually accompanied by another set of special leaves called sepals, that collectively form the ""calyx"" and lie just beneath the corolla. The calyx and the corolla together make up the perianth. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ""tepal"" is appropriate include genera such as ""Aloe"""
"A corolla of separate tepals is ""apopetalous"". If the petals are free from one another in the corolla, the plant is ""polypetalous"" or ""choripetalous""; while if the petals are at least partially fused together, it is ""gamopetalous"" or ""sympetalous"". In the case of fused tepals, the term is ""syntepalous"". The corolla in some plants forms a tube. Petals can differ dramatically in different species. The number of petals in a flower may hold clues to a plant's classification. For example, flowers on eudicots (the largest group of dicots) most frequently have four or five petals while flowers on monocots have"
"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 together with the sepals make up the perianth (perigon, perigonium). If the perianth is differentiated, the outer whorl of sepals forms the calyx, and the inner whorl of petals, the corolla. If the perianth is not differentiated into sepals and petals, they are collectively known as tepals. In some"
"Each flower has three to five leathery sepals that mostly end in a stretched tip, making it ""leafy"", but sometimes one and rarely two sepals may be obovate with a rounded tip, which do not fall after flowering. The corolla usually consists of six to nine oblong cyclamen or rarely pink to white petals of 3-6½ × 1½-3 cm. Towards the centre of the flower are many stamens consisting of filaments of ½–1 cm topped with anthers that ripen from the inside out, open with slits and release yellow pollen. The pollen is released in sets of four grains together."
"this may be augmented by more specialised structures like the corona (see below). When the corolla consists of separate tepals the term apotepalous is used, or syntepalous if the tepals are fused to one another. The petals may be united to form a tubular corolla (gamopetalous or sympetalous). If either the petals or sepals are entirely absent, the perianth can be described as being monochlamydeous. Both sepals and petals may have stomata and veins, even if vestigial. In some taxa, for instance some magnolias and water lilies the perianth is arranged in a spiral on nodes, rather than whorls. Flowers"
"growing for several years and only flowering once before it dies. Flowering is synchronized among plants in a given area, with widespread, picturesque blooms occurring periodically. It is not known why some plants in an area will not flower in a mass flowering event, or what cues the plants rely on to initiate flowering. The inflorescence is a tall, erect panicle with flowers densely clustered at the top and then spread out in interrupted clusters below. Each flower has a calyx of four pointed sepals and a corolla of four pointed lobes each one to two centimeters long. The corolla"

Each flowerhead may contain a few or up to over one hundred hermaphrodite or unisexual, star-symmetric or mirror-symmetric flowers. The petals are fused to form a funnel-shaped or sometimes cylinder-shaped corolla that is split into four to six lobes at the top. The corolla's remains stay on the top of the one-seeded dry fruit at maturity. Four or five stamens alternate with the corolla lobes. The lower third of these filaments are fused with the corolla tube, while sometimes filaments may"
"and ""Tulipa"". Conversely, genera such as ""Rosa"" and ""Phaseolus"" have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as ""petaloid"", as in petaloid monocots, orders of monocots with brightly coloured tepals. Since they include Liliales, an alternative name is lilioid monocots. Although petals are usually the most conspicuous parts of animal-pollinated flowers, wind-pollinated species, such as the grasses, either have very small petals or lack them entirely. The role of the corolla in plant evolution has been studied extensively since Charles Darwin postulated a theory of the origin of elongated corollae and corolla tubes."
"corolla is basally tubular and twice as long as the calyx, divided into three lobes, striate and valvate. There are six stamens with laterally connate filaments and oblong to ovate anthers, dorsifixed towards the base. The pollen is circular to elliptical and monosulcate; exine reticulate and tectate and irregularly spotted with striate spines; the tiny pistillode is trifid. In female plants the inflorescence usually features one main branch and the branchlets may grow from the main axil, the branch, or both. The branchlets are subtended by netlike bracts, often enclosing them, each small branch bearing up to 20 pistillate flowers,"
"four kinds of structures attached to the tip of a short stalk. Each of these kinds of parts is arranged in a whorl on the receptacle. The four main whorls (starting from the base of the flower or lowest node and working upwards) are as follows: Collectively the calyx and corolla form the perianth (see diagram). Although the arrangement described above is considered ""typical"", plant species show a wide variation in floral structure. These modifications have significance in the evolution of flowering plants and are used extensively by botanists to establish relationships among plant species. The four main parts of"
"Within the corolla throat, five tufts of hairs alternate with the stamens to form a ring. The colour of corolla varies from purple, violet or blue to shades of pink and red, or sometimes white. The colour of the flower in bud is often pink, which then changes as the flower matures. The stamens and style are included within the corolla and not protruding. The nutlets are smooth, egg-shaped, brownish, up to 4.5 mm long and 3 mm wide, each containing a single seed. Up to four nutlets per flower are produced, ripening mostly in summer. ""Pulmonaria"" species are used"

When the perianth is in two whorls, it is described as biseriate. While the calyx may be green, known as sepaloid, it may also be brightly coloured, and is then described as petaloid. When the undifferentiated tepals resemble petals, they are also referred to as ""petaloid"", as in petaloid monocots, orders of monocots with brightly coloured tepals.

"the term hemicyclic may be used. The suffix -cyclic is used to denote the number of whorls contained within a flower. The most common case is the pentacyclic flower, which contains five whorls: a calyx, a corolla, two whorls of stamens, and a single whorl of carpels. Another common case is the tetracyclic flower, which contains only one whorl of stamens, and therefore only four whorls in total. Tricyclic flowers also occur, generally where there is a single undifferentiated perianth. Flowers with more than five whorls are also not uncommon. The greatest variation occurs in the calyx and the androecium."

There is a tube-shaped outer calyx, some 2.5 cm long, which is hairy (pubescent), particularly along the veins, and is split on one side with two teeth at the end. Next the three petals (the corolla) form a tube which is shorter than the calyx and terminates in three lobes, a more-or-less oblong upright central lobe, about 2 cm long, which is hooded, and two side lobes, longer than the central lobe.
