Perigynous flowers are often referred to as having a half-inferior ovary (or, sometimes, partially inferior or half-superior). This arrangement is particularly frequent in the rose family and saxifrages. Occasionally, the gynoecium is born on a stalk, called the gynophore, as in Isomeris arborea.
A fruit is the mature, ripened ovary of a flower following double fertilization in an angiosperm.Because gymnosperms do not have an ovary but reproduce through fertilization of unprotected ovules, they produce naked seeds that do not have a surrounding fruit, this meaning that juniper and yew "berries" are not fruits, but modified cones.
The authors of a 2016 paper recommended using perigynium to refer generically to the flower prophyll of Carex sensu lato (including former Kobresia), but calling it utricle when it has its margins fused so it is entirely closed (as in the vast majority of Carex species). [9]
The flowers are perigynous with a bell- or urn-shaped hypanthium (base of the flower), usually externally covered with short, soft hairs (pubescent). There are usually five petals (sometimes four), purple to lilac, rarely white. The flowers have ten stamens (sometimes eight), often of two distinct sizes, with purple or pink anthers. The ...
A mature flower. In this example, the perianth is separated into a calyx (sepals) and corolla (petals) The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone.
Angiosperms The receptacle (grey) in relation to the ovary (red) in three types of flowers: hypogynous (I), perigynous (II), and epigynous (III). In angiosperms, the receptacle or torus (an older term is thalamus, as in Thalamiflorae) is the thickened part of a stem (pedicel) from which the flower organs grow.
