The World Checklist of Vascular Plants: names

Description

Usage

wcvp_checklist_names

Format

A data frame with 1,442,392 rows and 31 variables:

plant_name_id

World Checklist of Vascular Plants (WCVP) identifier

ipni_id

International Plant Name Index (IPNI) identifier. Missing values indicate that the name has not been matched with a name in IPNI.

taxon_rank

The level in the taxonomic hierarchy where the taxon nname fits. Some infraspecific names are unranked and will have no value iin this column.

taxon_status

Indication of taxonomic opinion re the name.

family

The name of the family to which the taxon belongs. (The highest rank at which names are presented in WCVP).

genus_hybrid

Indication of hybrid status at genus level: \+ indicates a graft-chimaera and × indicates a hybrid.

genus

The name of the genus to which the record refers.

species_hybrid

Indication of hybrid status at species level: \+ indicates a graft-chimaera and × indicates a hybrid.

species

The species epithet which is combined with the genus name to make a binomial name for a species. Empty when the taxon name is at the rank of genus.

infraspecific_rank

The taxonomic rank of the infraspecific epithet. Empty where the taxon name is species rank or higher. For more information, see the International Code of Nomenclature for algae, fungi and plants: https://www.iapt-taxon.org/nomen/main.php

infraspecies

The infraspecific epithet which is combined with a binomial to make a trinomial name at infraspecific rank. Empty when taxon name is at species rank or higher.

parenthetical_author

The author of the basionym. Empty when there is no basionym.

primary_author

The author or authors who published the scientific name. Missing values indicate instances where authorship is non-applicable (e.g. autonyms) or unknown.

publication_author

The author or authors of the book where the scientific name is first published, who are different from the primary author. Missing values indicate instances where the primary author is also the author of the book or non-applicable (e.g. autonyms).

place_of_publication

The journal, book or other publication in which the taxon name was effectively published. Missing values indicate instances where publication details are unknown or non-applicable (e.g. for autonyms). Abbreviated for brevity.

volume_and_page

The volume and page numbers of the original publication of the taxon name, where "5(6): 36" is volume 5, issue 6, page 36. Missing values indicate instances where publication details are unknown or non-applicable (e.g. for autonyms). Not all records include issue number.

first_published

The year of publication of the name, enclosed in parentheses. Missing values indicate instances where publication details are unknown or non-applicable (e.g. for autonyms).

nomenclatural_remarks

Remarks on the nomenclature. Preceded by a comma and space (", ") for easy concatenation.

geographic_area

The geographic distribution of the taxon (for names of species rank or below): a generalised statement in narrative form. See https://powo.science.kew.org/about-distribution#geography for details.

lifeform_description

The lifeform (or lifeforms) of the taxon. Terms refer to a modified version of the Raunkiær system. Where there are multiple lifeforms, the most common is listed first. Missing values if unknown. See https://powo.science.kew.org/about-distribution#lifeform for a glossary of terms used.

climate_description

Habitat type of the taxon, derived from published habitat information.

taxon_name

Concatenation of genus with species and, where applicable, infraspecific epithets to make a binomial or trinomial name.

taxon_authors

Concatenation of parenthetical and primary authors. Missing values indicate instances where authorship is unknown or non-applicable (e.g. autonyms).

accepted_plant_name_id

The ID of the accepted name of this taxon. Where the taxon_status is "Accepted", this will be identical to the plant_name_id value. Maybe empty if taxon status is unplaced, illegitimate, or in some cases where the accepted name is not a vascular plant (e.g. a moss, alga or animal).

basionym_plant_name_id

ID of the original name that taxon_name was derived from (i.e. the basionym). Empty if there have been no name changes.

replaced_synonym_author

The author or authors responsible for publication of the replaced synonym. Empty when the name is not a replacement name based on another name.

homotypic_synonym

The synonym type - TRUE if homotypic synonym, otherwise NA. See more information, see the International Code of Nomenclature for algae, fungi and plants: https://www.iapt-taxon.org/nomen/main.php

parent_plant_name_id

ID for the parent genus or parent species of an accepted species or infraspecific name. Empty for non accepted names or where the parent has not yet been calculated.

powo_id

Identifier required to look up the name directly in Plants of the World Online (POWO).

hybrid_formula

Parents of hybrid.

reviewed

Flag indicating whether the family to which the taxon belongs has been peer reviewed.
