The dataset represents a comprehensive collection of occurrence records concerning the genus
In total, 2,280 occurrence records of the genus
The Ukrainian Carpathians are one of the principal centres of floristic diversity and endemism in Ukraine, serving as a home for over 2500 plant species (
For all of these investigations, initial distribution information, based on herbarium material and field observations, is required. Access to Ukrainian herbarium collections has remained restricted for the last few years due to pandemic limitations (
The purpose of creating this dataset was to gather and georeference all available data on the distribution of representatives of the genus
The dataset contains information on 2,280 occurrences of
Initially, the working list of 28 species and infraspecific taxa of the genus
The data were cross-checked for correct identification and known distribution areas to delimit potential errors and outlets. In case of doubt or impossibility of a correct identification of species, the specimens were omitted from the analysis. In case of unusual reports from the new areas, such occurrences were critically revised or omitted due to a high risk of misidentification.
The following steps were taken before working with the herbarium material:
Creation of a list of Clarification of the supraspecific and infraspecific taxonomy and morphology of the listed species to delimit similar and phylogenetically related taxa that potentially can be misidentified or confused; Creation of the identification key with indication of similar taxa; Creation of a working checklist with the nomenclatural synonyms of selected
The following steps were taken during the work with herbarium materials:
Photo capture of herbarium vouchers of selected species; Taxonomic revision of specimens following recent taxonomy; Parsing and databasing the information (i.e. locality, collector, date and other relevant data) from the labels following the DarwinCore standard; Translation of Cyrillic (i.e. Ukrainian and Russian) data from labels into English; Georeferencing and verification of localities; Quality check applying OpenRefine.
The following steps were taken during the work with literature sources:
Verification of the authors on their authority; Extraction of reported data to the dataset following the DarwinCore standard; Translation of Cyrillic (i.e. Ukrainian and Russian) data into English; Georeferencing and verification of localities; Quality check applying OpenRefine.
The occurrences from the Ukrainian Carpathians and adjacent territories were considered (Fig.
47.8 and 51.5 Latitude; 22.7 and 25.9 Longitude.
All analysed specimens and occurrence reports were identified to the lowest possible rank, usually to the level of species or subspecies. As a result, the dataset generally contains 40

The tab-delimited CSV formatted dataset (
Column label | Column description |
---|---|
occurrenceID | An unique identifier for the Occurrence (as opposed to a particular digital record of the occurrence). |
basisOfRecord | The specific nature of the data record, for example, preserved specimen or field observation. |
collectionCode | Unique code of collection (e.g. herbarium) for the specimen deposited. |
institutionCode | Unique code of institution (e.g. museum or herbarium) for the specimen deposited. |
catalogNumber | An identifier for the record within collection. |
scientificName | The full scientific name of taxon including at least the genus and species epithets and, in some cases, including the subspecies epithet. |
taxonRank | The taxonomic rank of the most specific name in the scientificName. |
recordedBy | A person, group or organisation responsible for recording the original Occurrence. |
verbatimEventDate | The date of record as it appears in the original publication or specimen's label. |
EventDate | The date during which an event (e.g. collection of the specimen, photographing of the plant or its registering in the field in any other way), occurred. |
day | The day when occurrence was recorded. |
month | The month when occurrence was recorded. |
year | The year when occurrence was recorded. |
fieldNumber | An identifier given to the specimen in the field by the collector. |
identifiedBy | A list of names of people who assigned the Taxon to the subject, |
dateIdentified | The date on which the subject was determined as representing a certain Taxon. |
identificationRemarks | Comments or notes about the Identification. |
decimalLatitude | The geographic latitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic centre of a Location. |
decimalLongitude | The geographic longitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic centre of a Location. |
coordinateUncertaintyInMetres | The horizontal distance (in metres) from the given decimalLatitude and decimalLongitude describing the smallest circle containing the whole of the Location. |
geodeticDatum | The ellipsoid, geodetic datum or spatial reference system (SRS) upon which the geographic coordinates given in decimalLatitude and decimalLongitude are based. In our case, it is always WGS84. |
verbatimElevation | The original description of the elevation (altitude, usually above sea level) of the Location. |
countryCode | The standard code (ISO 3166-1-alpha-2) for the country in which the Location occurs. |
country | The name of the country in which the Location occurs. |
locality | The specific description of the place where the specimen was registered or collected. |
verbatimLocality | The original textual description of the place where the specimen was registered or collected. |
fieldNotes | The original text of notes taken in the field about the specimen by the collector. |
associatedReferences | A list (concatenated and separated) of identifiers (publication, bibliographic reference, global unique identifier, URI) of literature associated with the Occurrence. |
kingdom | The full scientific name of the kingdom in which the taxon is classified. In our case, it is always |
language | The language of the resource. In our case, herbarium labels contained information in different languages and sometimes different languages were even combined on a single label. To simplify the work with data, we indicated the languages applied for the data. |
minimumElevationInMetres | The lower limit of the range of elevation (altitude, usually above sea level) in metres. |
maximumElevationInMetres | The upper limit of the range of elevation (altitude, usually above sea level) in metres. |
