ppendemic_tab15: Endemic Plant Database of Peru (based on WCVP v15)
Source:R/ppendemic_data.R
ppendemic_tab15.RdThe ppendemic_tab15 dataset is a tibble (data frame) providing a curated
and taxonomically validated list of vascular plant species that occur exclusively
in Peru. The dataset is derived from version 15 of the World Checklist of Vascular
Plants (WCVP), facilitated by the Royal Botanic Gardens, Kew, and corresponds to
the extraction performed on 06 January 2026.
Format
A tibble (data frame) with 7,892 rows and 18 columns:
- taxon_name
Character vector. The full scientific name of the accepted endemic species (binomial or trinomial), constructed from genus, species and, where applicable, infraspecific epithets, following WCVP standards.
- taxon_status
Character vector. The taxonomic status of the name according to WCVP (e.g.,
"Accepted").- family
Character vector. The botanical family to which the endemic taxon belongs, following WCVP family circumscription.
- Genus
Character vector. The genus name of the endemic taxon.
- Species
Character vector. The specific epithet of the endemic taxon.
- infraspecific_rank
Character vector. The infraspecific rank (e.g.,
"subsp.","var.") when applicable.- infraspecies
Character vector. The infraspecific epithet when applicable.
- taxon_authors
Character vector. The standardized authorship of the taxon name, concatenating parenthetical and primary authors following botanical nomenclature conventions.
- primary_author
Character vector. The author(s) who validly published the scientific name.
- place_of_publication
Character vector. The journal, book or other publication in which the taxon name was effectively published.
- volume_and_page
Character vector. The volume and page reference of the original publication of the taxon name (e.g.,
"13(2): 99").- first_published
Character vector. The year of publication of the name, enclosed in parentheses, as reported by WCVP.
- year_actual
Numeric vector. The actual year of publication extracted from
first_published.- year_nominal
Numeric vector. The nominal year of publication extracted from
first_published.- both_years
Character vector. A concatenation of actual and nominal years when these differ (format
"YYYY|YYYY").- has_different_years
Logical vector. Indicates whether the actual and nominal publication years differ.
- version
Character vector. The database version identifier
"V-15", corresponding to WCVP version 15.- version_date
Character vector. The extraction date of the WCVP source dataset (
"06-01-2026").

Details
This database contains only accepted endemic species names, following the taxonomic backbone of WCVP and filtered by geographic distribution records indicating occurrence restricted to Peru.
The dataset was constructed from the World Checklist of Vascular Plants (WCVP) version 15, a continuously updated global taxonomic resource curated by the Royal Botanic Gardens, Kew. Only taxa of rank species and below with accepted status were considered.
Geographic distribution fields from WCVP were used to identify taxa whose native range is restricted exclusively to Peru. Introduced, cultivated, misapplied, synonymic and unplaced names were excluded.
The nomenclature, authorship, family assignment and publication details strictly follow the International Code of Nomenclature for algae, fungi and plants (ICN) and WCVP editorial standards.
Temporal metadata was processed to extract both nominal and actual publication years, allowing detailed historical bibliographic analysis of Peruvian endemic flora.
