Information about Hybrid Name
In botanical nomenclature, a hybrid may be given a hybrid name, which is a special kind of botanical name. The ICBN provides the following options in dealing with a hybrid:
A hybrid name is unlike other botanical names in that it does not necessarily refer to a cohesive unit but applies to all progeny of the parents, no matter how much the variation. So, Magnolia ×soulangeana applies to all progeny from the cross Magnolia denudata × Magnolia liliiflora, and from the crosses of all their progeny, as well as from crosses of any of the progeny back to the parents. This covers quite a range in flower color.
The multiplication sign should be put before the name in case of intergeneric hybrid and otherwise before the relevant epithet. Only when a multiplication sign is not available (e.g., on some typewriters), a small letter "x" may be used as a replacement. Examples :
The provisions in the ICBN that deal with hybrid names are Art H.1 to H.12.
- A hybrid may get a normal botanical name; this will usually be the option of choice for naturally occurring hybrids.
- A hybrid may also be indicated by a formula listing the parents. Such a formula uses the multiplication sign "×" to link the parents.
- A hybrid name is usually reserved for horticulturally arising hybrids and artificial and/or forced hybrids. A hybrid name is indicated by a multiplication sign "×" placed before the name or epithet, as the case may be.

- Dianthus ×allwoodii (the equivalent formula is Dianthus caryophyllus × Dianthus plumarius). This is an "interspecific hybrid" (a hybrid between two species in the same genus): the multiplication sign goes before the epithet.
- ×Heucherella tiarelloides (the equivalent formula is Heuchera sanguinea × Tiarella cordifolia). This is an "intergeneric hybrid" (a hybrid between two different genera): the multiplication sign is placed before the generic name. This generic name is a so-named "nothogeneric name" and is a condensed formula, formed from the generic names of the parents: eg ×Heucherella combines Heuchera and Tiarella).
The provisions in the ICBN that deal with hybrid names are Art H.1 to H.12.

Botanical nomenclature is the formal naming of plants, from a scientific point of view. It has a long history, going back perhaps to Theophrastos, but anyway back to the period when Latin was the scientific language throughout Europe.

hybrid has two meanings.[1]
The first meaning is the result of interbreeding between two animals or plants of different taxa. Hybrids between different species within the same genus are sometimes known as interspecific hybrids or crosses.

The multiplication sign is the symbol × (multiplication sign is the preferred Unicode name for the codepoint represented by that glyph). The symbol is similar to the letter x but is a more symmetric cross, and has different uses.

In biology, a homonym is a name for a taxon that is identical in spelling to another such name, that belongs to a different taxon.

graft-chimaera may arise in grafting at the point of contact between rootstock and scion and will have properties intermediate to those of its "parents". A graft-chimaera is not a true hybrid but a mixture of cells, each with the genotype of one of its "parents": it is a chimaera.
