Information About

Monotypic




  • in Botany it means that a Taxon has only one Species ; ''Ginkgo'' is a monotypic Genus , while ''Ginkgoaceae'' is a monotypic family. The phrase is not really accurate, as it assumes that a Species includes only a single Type . This is not necessarily the case as a Species may include several Subspecies (or other infraspecific Taxa ) each of which will have a type. A more accurate term is "unispecific".

  • :: An example is the Genus '' Darlingtonia '', with only one Species : ''Darlingtonia californica''.


  • in Zoology "monotypic" refers to a Taxon that contains only one immediately subordinate Taxon .Mayr E, Ashlock PD. 1991. Principles of Systematic Zoology. Second Edition. Published by McGraw-Hill, inc. ISBN 0-07-041144-1. For example, a monotypic Genus has only one Species . Conversely, one can say that the contained Taxon is monotypic within the larger Taxon ; a Genus monotypic within a family.

  • :: An example is the Genus '' Tarsius '' which is monotypic within the Tarsiidae family (which is itself monotypic in Tarsiiformes ). An example of a monotypic Species is the Hyacinth Macaw (''Anodorhynchus hyacinthinus'') which, discounting the nominate Taxon , does not include any subordinate Taxa ( Subspecies ). On the contrary the Mealy Parrot (''Amazona farinosa'') is not a monotypic Species , as it has several subordinate Taxa ( Subspecies ).
