PNW Herbaria Synonymized Checklist:

This checklist is maintained by the Consortium of Pacific Northwest Herbaria as a working list of scientific names and synonymy for vascular plants, bryophytes, algae, lichens, and fungi. The checklist is used to assign currently accepted taxon names to specimen records in the CPNWH database. The completeness of the checklist varies by taxonomic group, with vascular plants found in the Pacific Northwest updated most frequently.

The original checklist was created by combining information from multiple sources. Vascular plant names and synonymy were obtained primarily from the Washington Flora Checklist, Oregon Flora Project, Montana Natural Heritage Program, B.C. Ministry of Forests, and Flora of north America. Additional names and synonymy for vascular plants and other taxonomic groups were obtained from USDA Plants, ITIS, and the North American Lichen Checklist. The PNW Herbaria checklist is now updated and maintained independently, and has diverged in many places from those initial lists.

Checklist structure:

The checklist contains 3 tables (represented as tabs in the Excel file, or text files in the zip archive). The contents of each table, and an explanation of the columns in each, is provided here.


Scientific Names:

The Scientific Names table contains one record per scientific name. Names are represented at the ranks of family, genus, species, and infraspecies (e.g., subspecies, variety, and forma). Each scientific name is assigned to a currently accepted taxon name. The NameID column serves as the unique identifier of each name within the PNW Herbaria database.

Column: Explanation:
ITIS_TSN The Taxonomic Serial Number for this scientific name in the ITIS database (https://www.itis.gov/). This value is not populated for names added to the checklist after the initial download from ITIS.
Hybrid Indicates if the scientific name represnts a named or unnamed hybrid. Allowed values: Named, Unnamed
Homonym Indicates if the scientific name is a homonym within this checklist. Homonyms are spelled the same but have different authors and may represent different taxa.
NameRank The rank of this scientific name. Allowed values: family, genus, species, infraspecies
NameID A unique integer identifier assigned to each scientific name in this checklist; forms the basis for linking instances of this name across different tables.
ScientificName The full scientific Name, consisting of the appropriate name epithets without authors. Hybrid symbols are left out for named hybrids (for sorting purposes) but included for unnamed hybrids.
Accepted A Yes/No flag indicating whether this name is accepted or not. Most names that are not accepted are synonyms. Allowed values: Y, N
NameStatus The nomenclatural status of this scientific name, of not accepted. The possible values are too numerous to list here, but most names are marked as a synonym.
TaxonID The TaxonID represnts the NameID of the taxon name, and correponds to a value in the NameID column. A given TaxonID and TaxonName may appear for multiple scientific names (most being synonyms of that taxon name).
TaxonName The taxon name (= accepted name) to which the scientific name is currently referred.
SeeAlso For ambiguous names that cannot be resolved to a single taxon name, this field lists the possible taxon names to which the name might correspond, with an emphasis on our area (the Pacific Northwest).
SynonymySources A list of acronyms indicating the soure checklists and floras that use the same synonymy as given here, valid at the time those sources were consulted while building the PNW Herbaria checklist. A value of PNW means the synonymy has been updated after those sources were initially consulted.
InformalClassification A colon-separated list of one or more informal names above the rank of family, in which this scientific name is classified. These are intended as a simple and user-friendly means of grouping families and scientific names into major recognizable groups.
Family The name of the currently accepted family in which this scientific name is classified.
FamilyAuthors Authors for the family name; only populated for names at the rank of family.
NothoGenus If a named infrageneric hybrid, this column holds the hybrid symbol (×) that will be prepended to the genus for display purposes.
Genus Epithet for genus name.
GenusAuthors Authors of genus name, generally abbreviated following standards.
NothoSpecies If a named infraspecific hybrid, this column holds the hybrid symbol (×) that will be prepended to the species epithet for display purposes.
SpecificEpithet Epithet for species name.
SpecificAuthors Authors of species name, generally abbreviated following standards.
InfraspecificRank Abbreviation for the rank of an infraspecies name: ssp. (subspecies), var. (variety), or f. (forma).
NothoInfraspecies If a named hybrid at the rank of infraspecies, this column holds the hybrid symbol (×) that will be prepended to the infraspecies epithet for display purposes.
InfraspecificEpithet Epithet for subspecies, variety, or forma name.
InfraspecificAuthors Authors of subspecies, variety, or forma name, generally abbreviated following standards.
HybridSymbol This field, and those that follow, are used for the second parent of unnamed hybrids; this field holds the hybrid symbol separating the parent names (generally an ×, but possibly <, <<, >, or >>).
NothoGenus2 Same as NothoGenus, but for second parent name.
Genus2 Same as Genus, but for second parent name.
GenusAuthors2 Same as GenusAuthors, but for second parent name.
NothoSpecies2 Same as NothoSpecies, but for second parent name.
SpecificEpithet2 Same as SpecificEpithet, but for second parent name.
SpecificAuthors2 Same as SpecificAuthors, but for second parent name.
InfraspecificRank2 Same as InfraspecificRank, but for second parent name.
NothoInfraspecies2 Same as NothoInfraspecies, but for second parent name.
InfraspecificEpithet2 Same as InfraspecificEpithet, but for second parent name.
InfraspecificAuthors2 Same as InfraspecificAuthors, but for second parent name.
Cultivar The epithet applied to a named horticultural cultivar; does not include the 'cv.' prefix or single quotes (those are added for display purposes).
Aggregate The epithet applied to a species aggregate or group; occasionally used for apomictic species complexes or for fungi.
HybridParents The scientific names of the two parents of a named hybrid, separated by an ×.
YearPublished Year when the scientific name was published (not yet provided for most names).
Publication Citation for the publication of the name (not yet provided for most names).
Comments Free-text field with any comments pertinent to the scientific name or its application and synonymy.


Misapplied Names:

This table lists misapplied names, with an emphasis on the Pacific Northwest. A misapplied name cannot be treated as a synonym since the misapplied name generally remains accepted elsewhere. Each misapplied name record is valid for the indicated geographic area and is assigned to an accepted taxon name within that area. These misapplications may not be valid outside the indicated geographic areas.

Column: Explanation:
Country The country in which the name has been misapplied.
StateProvince The state, province, or similar political jurisdiction in which the name has been misapplied; if left blank, then the name is considered misapplied for the entire country.
NameID NameID corresponding to the scientific name record in the Scientific Names table.
ScientificName The scientific name that has been misapplied within the indicated political jurisdiction.
TaxonID The NameID for the current taxon name (= accepted name) to which the misapplied name should be referred in the indicated political jurisdiction.
TaxonName The current taxon name (= accepted name) to which the misapplied name should be referred in the indicated political jurisdiction.
Comments Comments clarifying the status of the misapplied name.


Taxa of Concern:

This table lists taxa of conservation concern (rare plants) that have been assigned a formal status within a given political jurisdiction. Each record is applicable only to the given taxon within the political jurisdiction. The sources of these records include state natural heritage programs and the USDA Plants database. These records are applied to matching specimens in the PNW Herbaria database to obscure their precise localities to help protect rare plant populations.

Column: Explanation:
NameID NameID corresponding to the scientific name record in the Scientific Names table.
ScientificName The scientific name as used by the entity that manages this taxon as a species of conservation concern.
TaxonID The NameID for the current taxon name (= accepted name) to which the scientific name is referred in the Scientific Names table.
TaxonName The current taxon name (= accepted name) to which the scientific name is referred in the Scientific Names table.
Country The country in which this species is listed as a species of conservation concern.
StateProvince The state, province, or similar political jurisdiction in which this species is listed as a species of conservation concern; if blank, then the listing applies to the entire country.
StatusCode A conservation status code assigned to this scientific name by the entity that manages this taxon.
Status The spelled-out status of this scientific name, assigned by the entity that manages this taxon.
Sources Acronym indicating the entity (e.g, a Natural Heritage Program) from which the record for this species of conservation concern was obtained.
