Nothospecies


In botanical nomenclature, a hybrid may be given a hybrid name, which is a special kind of botanical name, but there is no requirement that a hybrid name should be created for plants that are believed to be of hybrid origin. The International Code of Nomenclature for algae, fungi, and plants (ICNafp) provides the following options in dealing with a hybrid:

A hybrid name is treated like other botanical names, for most purposes, but differs in that:

Hybrids can be named with ranks, like other organisms covered by the ICNafp. They are nothotaxa, from notho- (hybrid) + taxon. If the parents (or postulated parents) differ in rank, then the rank of the nothotaxon is the lowest. The names of nothospecies differ depending on whether they are derived from species within the same genus; if more than one parental genus is involved, then the nothospecies name includes a nothogenus name.

A hybrid name can be indicated by:

The multiplication sign and the prefix notho- are not part of the actual name and are disregarded for nomenclatural purposes such as synonymy, homonymy, etc. This means that a taxonomist could decide to use either form of this name: Drosera ×anglica to emphasize that it is a hybrid, or Drosera anglica to emphasize that it is a species.

The names of intergeneric hybrids generally have a special form called a condensed formula, e.g., Agropogon for hybrids between Agrostis and Polypogon. Hybrids involving four or more genera are formed from the name of a person, with suffix -ara, e.g., ×Beallara. Names for hybrids between three genera can be either a condensed formula or formed from a person's name with suffix -ara.
