Monotypic taxon Information

In biology, a monotypic taxon is a taxonomic group ( taxon) that contains only one immediately subordinate taxon. [1] A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. [2] In contrast an oligotypic taxon contains more than one but only a very few subordinate taxa.

Examples

Just as the term monotypic is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are:

Plants

  • In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, Amborella, and in this genus there is only one species, namely Amborella trichopoda.
  • The flowering plant Breonadia salicina is the only species in the monotypic genus Breonadia.
  • The family Cephalotaceae includes only one genus, Cephalotus, and only one species, Cephalotus follicularis – the Albany pitcher plant.
  • The division Ginkgophyta is monotypic, as the only extant species is Ginkgo biloba. [3]
  • Flowering plant Nandina domestica is the only species in the genus Nandina.
