The World Checklist of Vascular Plants: names
wcvp_names.RdA dataset containing the taxonomic data from the WCVP.
Format
A data frame with 1,415,007 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 or authors responsible for publication of the original scientific name. Empty when no name change has occurred.
- primary_author
The author or authors responsible for publication of the scientific name. Missing values indicate instances where authorship is unknown or non-applicable (e.g. autonyms).
- publication_author
The author or authors of the publication where the scientific name is first published (may be different from primary author if e.g. described in a book). Missing values indicate instances where publication details are unknown or non-applicable (e.g. for autonyms).
- place_of_publication
The journal, bulletin or other publication that the taxon name was first published in. Missing values indicate instances where publication details are unknown or non-applicable (e.g. for autonyms).
- 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).
- first_published
The year of publication of the taxon 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.
- geographic_area
The geographic distribution of the taxon (for names of species rank or below): a generalised statement in narrative form.
- lifeform_description
The lifeform (or lifeforms) of the taxon. Terms refer to a modified verison of the Raunkiær system. Where there are multiple lifeforms, the most common is listed first. Missing values if unknown.
- 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. May be empty if taxon status is unplaced, ilegitimate, 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.
- 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.
