In biology, gonochorism ("Greek" offspring + disperse) or unisexualism or gonochory describes the state of having just one of at least two distinct sexes in any one individual organism.
 The term is most often used with animals, in which the individual organisms are often gonochorous.
 Gonochory is less common in plants.
 For example, in flowering plants, individual flowers may be hermaphrodite (i.e. with both stamens and ovaries) or gonochorous (unisexual), having either no stamens (i.e. no male parts) or no ovaries (i.e. no female parts).
 Among flowering plant species that have unisexual flowers, some also produce hermaphrodite flowers, and the three types occur in different arrangements on separate plants; the plants can be monoecious, dioecious, polygamomonoecious, polygamodioecious, andromonoecious, or gynomonoecious.
Ammobium is genus of perennial Asteraceae species described as a genus in 1824.
Mespilus, commonly called medlar, is a monotypic genus of flowering plants in the family Rosaceae containing the single species "Mespilus germanica" of southwest Asia.
 A second proposed species, "Mespilus canescens", discovered in North America in 1990, proved to be a hybrid between "M. germanica" and one or more species of hawthorn, and is properly known as ×"Crataemespilus canescens".
Mentzelia affinis is a species of flowering plants in the family Loasaceae known by the common name yellowcomet.
 It is native to the southern half of California, Arizona, and adjacent sections of Nevada and Baja California, where it is known from scrub, woodland, desert sands, and other habitat types.
Malacomeles (false serviceberry) is a genus of flowering plants in the Rosaceae.
 It is most closely related to "Amelanchier", "Peraphyllum", "Crataegus", and "Mespilus".
Tessmannianthus is a genus of flowering plants in the family Melastomataceae.
 There are seven species distributed in Central and South America.
 They are medium to large trees up to 40 meters tall.
 The flowers are heterantherous, bearing two types of stamens.
 These plants are rare, and some are narrow endemics known from only one location.
Exochorda is a small genus of flowering plants in the family Rosaceae, native to China and central Asia (Turkestan).
 They are used as ornamental plants with the common name pearl bush, or pearlbush.
 Numerous species have been described on the basis of differing appearance and geographical separation, but a systematic study revealed that the different types are closely related and probably all descended from a single species that formerly had a wide distribution that has been fragmented by habitat loss.
 As a single species the correct name is "E. racemosa".
Vigna is a genus of flowering plants in the legume family, Fabaceae, with a pantropical distribution.
 It includes some well-known cultivated species, including many types of beans.
 Some are former members of the genus "Phaseolus".
 According to "Hortus Third", "Vigna" differs from "Phaseolus" in biochemistry and pollen structure, and in details of the style and stipules.
A vessel element or vessel member (trachea) is one of the cell types found in xylem, the water conducting tissue of plants.
 Vessel elements (tracheae) are typically found in flowering plants (angiosperms) but absent from most gymnosperms such as conifers.
 Vessel elements are the main feature distinguishing the "hardwood" of angiosperms from the "softwood" of conifers.
Self-pollination is when pollen from the same plant arrives at the stigma of a flower (in flowering plants) or at the ovule (in Gymnosperms).
 There are two types of self-pollination: In autogamy, pollen is transferred to the stigma of the same flower.
 In geitonogamy, pollen is transferred from the anther of one flower to the stigma of another flower on the same flowering plant, or from microsporangium to ovule within a single (monoecious) Gymnosperm.
 Some plants have mechanisms that ensure autogamy, such as flowers that do not open (cleistogamy), or stamens that move to come into contact with the stigma.
 The term selfing that is often used as a synonym, is not limited to self-pollination, but also applies to other types of self fertilization.
