Perigonium: bot. Perianth of flower, not differentiated into calyx and corolla and made up of tepals. Definition and meaning of the term perigonium The perianth or, in the most archaic form, perianth or bowl (from the Greek perianthos comp. From peri-, around, and anthos, flower) is the part of the flower made up of the whole of the chalice and corolla, that is, of the outermost floral whorls when these are morphologically distinct. It constitutes the non-reproductive part of the flower The perigonum can resemble a corolla (if it is composed of petaloid tepals: see Lilium) or a chalice (if it has sepaloid tepals: see hellebore). Some examples of flowers with perigonum. Classic examples of flowers in which one prefers to use the term tepals and therefore perigonium are
Perianth. The perianth (from the Greek perianthos comp. from peri-, around, is anthos, flower) is the portion of the flower made up of the whole chalice is of the corolla or of the outermost floral whorls when these are morphologically distinct The perianth and the perigonium The perianth is formed by the outermost floral whorls (calyx and corolla). Considering the presence or absence of these whorls, the flower can be: Aclamidate (or naked) when it lacks the calyx and the corolla, that is the perianth or the perigonium (euphorbia, willow, ash). Chlamydate (or dressed) if it is provided with at least one of the aforementioned whorls, and in. The term perianth derives from the Greek περί (peri, around) and άνθος (anthos, flower), while perigonium derives from περί (peri) and γόνος (gonos, seed, sexual organs). In mosses and liverworts (Marchantiophyta), the perianth is the sterile tubular tissue surrounding the female reproductive structure (or the developing sporophyte)
If there is no difference between the external whorl and the internal whorl, the floral envelope is called perigonium while the floral leaves are called tepals. In the hepatics the perianth is made up of the tubular sheath that first surrounds the archegonium and then the sporophyte The perianth is therefore formed by two parts: the corolla, formed by the petals which are the colored parts of the flowers. attract pollinating animals. the calyx, the green part of the flower, has a more robust consistency than the corolla and its parts are called sepals. Considering the presence or absence of these verticils, the flower can be classified as. Both make up that part of the flower known as the perianth. When the distinction between the two is not so evident, we speak of perigonium and each element of which it is composed takes the name of tepalo
Perianth and Perigonium. Taking into account their specialization, the anthophylls are sterile or fertile. Sterile Antofilli do not participate directly in sexual reproduction and are the components of. perianth (or the perigonium) which is formed by the outermost floral whorls, the calyx composed of the sepals and the corolla formed by the petals The perianth or, in the most archaic form, perianth or bowl (from the Greek perianthos comp. from peri-, 'around ', and anthos, flower) is the part of the flower constituted by the whole of the calyx and the corolla, that is to say the outermost floral verticils when these are morphologically distinct. It constitutes the non-reproductive part of the flower. The perianth is therefore made up of two parts

Ceschin Goblet The floral pieces that make up the goblet are called sepals and are generally green in color as they assume a protective function. For the purposes of the system, two types of chalice are distinguished
. The perianth is formed by outermost floral whorls (calyx and corolla). Considering the presence or absence of these whorls, the flower can be: Aclamidate (or naked): when the chalice and corolla are missing, that is, without perianth and perigonium (euphorbia, willow, ash) a. simple perianth (perigonium) b. perianth with free petals and sepals c. perianth with increased petals and sepals Towards the inside there are, in the perianth, one or more series of stamens which consist of a mostly thin filament bearing at the apex the anthers (or pollen sacs) which contain, in fact, the pollen (cf. .) The perianth is formed by the floral whorls of the calyx and corolla. If the perianial leaves are tepal (lily, tulip, gladiolus) the perianth is called perigonium (monocotyledons). Depending on its shape and color, the perigonium can take on a corolline aspect (petaloid tepals) or calicine aspect (sepaloid tepals.
The two verticils that form the perianth can be morphologically different or not. Considering the presence or absence of these whorls, the flower can be: Aclamidate (or naked) when it lacks the calyx and the corolla, i.e. the perianth or the perigonium (euphorbia, willow, ash) Sepals and petals are very often divided, to form a structure that we call perianth, in some plants instead petals and sepals are fused together, they are not distinct, then in this case they are called tepals, the whole of which forms the perigonium Perianth with undifferentiated elements. Differentiated perianth in calyx and corolla → absence of petals and / or sepals → perigonium. Free floral pieces between them.

The perigonium is the equivalent of the perianth, it takes this name when the calyx and the corolla are not distinguishable. One of the orchid's petals, the central one, is called labellum and has a different appearance from the other two in order to attract the insects necessary for pollination. It can have different sizes and colors depending on the species Perianth and perigonium Sepals Petals The first two verticils (calyx and corolla), if morphologically different, form the perianth (most dicotyledons) If the first two verticils, if formed by similar elements (tepals), form the perigonium (monocotyledons and dicotyledons with anemogamous pollination) Tepal perianth: it is the 'floral envelope, consisting of the petals and sepals. perigonium: floral envelope (like the perianth) with non-distinct petals and sepals, replaced by tepals. proximal: this is the part of an organ closest to the point of insertion on the plant. prostrate: it is said of an organ (eg stem) entirely attached to the substrate If sepals and petals are not differentiated from each other they are called tepals and the perianth is called perigonium. The perianth, however, is generally divided into chalice (green) and corolla (colored). The chalice is the outermost series of elements of the perianth and is made up of green sepals that can grow apart or grow together: in the first case the chalice is called dialysepal, in the second. The perianth is the envelope that is externally to the flower with a protective and often vexillary function. It is formed by a chalice and corolla, generally with a constant number of pieces for a family and different from each other, if the same, the perianth is called perigonium
3. Perianth formed by elements (petals, sepals or tepals) completam. distinct or null (coripetal) 4. Fi. without vexillary function (therefore perianth formed by sepals only or by greenish elements with a sepaloid aspect or null perianth Calyx and corolla form the perianth and can be replaced by petals which form the perigonium. The androecium is the set of stamens, sexual organs male. Each stamen includes a filament inserted on the receptacle (or on the corolla) and a two-lobed anther, each containing two pollen sacs
The first subdivision of the flowers is between those with perianth and those with perigonum. Those with perianth have the corolla of petals and the calyx of sepals, have the thalamus or receptacle that contains the sexual part of the flower composed of different stamens and one or more pistils the ovary can be: superior, semi-inferior, inferior. only flowers with elements of the perianth all the same to form the perigonium, formed by the set of tepals. The flowers do not always present the fertile male and female parts together. If only the stamens are present, the flowers are called masculine. The perianth and the perigonium The perianth is formed by the outermost floral whorls (calyx and corolla). Considering the presence or absence of these whorls, the flower can be: Aclamidate (or naked) when it lacks the calyx and the corolla, i.e. the perianth or the perigonium (euphorbia, willow, ash) The sporophyll is a leaf that bears the sporangia. Perianth and perigonium have above all the function of attracting insects. Often, near a flower or an inflorescence, there are bracts, particular leaves, generally small and robust, which can have a protective function of the buds, but also nectar or disseminator Perianth meaning. perianth [pe-riàn-zio]. s.m.
