Taxonomic concept
Taxon : Vitis riparia
Accepted
Synonym(s) : Vitis riparia var. syrticola, Vitis riparia var.
praecox, Vitis cordifolia var. riparia, Vitis vulpina subsp. riparia,
Vitis vulpina var. syrticola
Excluded from concept
: NA
NatureServe Concept Reference: Kartesz 1994
Relationship to Flora of North America: Equal
Taxonomic Notes: Flora of North America (2016) does not
recognize varieties or subspecies of Vitis riparia. Specifically, plants
recognized as V. riparia var. syrticola (found on dunes around the Great
Lakes, see Catling and Mitrow 2005) were found to be synonymous with V.
riparia because the variation in leaf hairiness is continuous rather
than distinct (Flora of North America 2016). Additional varieties and
subspecies have been recognized in the past, including var. praecox, but
none are considered distinct by Flora of North America (2016) and most
local floras. Vitis riparia naturally hybridizes with other Vitis
species and is thought to be one of the parents of of Vitis x
novae-angliae with V. labrusca (Flora of North America 2016, Wen et
al. 2018).

Details on the map elements
County Level Features
All county level features report information that as aggregated to the county level. This include text reference to the county (state/county) and spatial point reference that occur within the county.
Counties with a record: This presence absence map shows a county as green if it has at least one record from any of the evaluated sources.
Sum of records within County: This layer depicts the total number of unique records of a species across all sources within a county.
Counties listed in USDA Plants and/or Bonap Only (No occurrence points) These counties only contain a reference from USDA Plants and/or BONAP. There are no identified iNaturalist, herbarium, or germplasm occurrences from these locations.
Counties with one or more Herbarium or Germplasm Occurrence: : hese counties have at least one herbarium and/or germplasm occurrence. There may also be additional records within this county(iNaturalist, USDA Plants, BONAP, NatureServe).
Counties with iNaturalist Observation only: These counties only have species observations from iNaturalist.
Occurrence Features
Germplasm Occurrences: : Occurrence data with living specimens stored in a Genebank or Botanical Garden.
Herbarium Occurrences with web url: Occurrence data of herbarium specimens, which includes an url for the source herbarium data.
Herbarium Occurrences without web url: Occurrence data of herbarium specimens.
iNaturalist observation data:: Research grade observations from iNaturalist.
General Methods
Gathering Data
Data was gathered at the Genus level from the following
public repositories
Sourced through communication with data owners
- 2023 Botanical Garden Survey – available in the full source data
- BONAP
- IUCN
Data Standardization and Taxonomy
data standardization : All data sets were altered to matched a standard data structure. The specific translation of data sets can be seen here.
Taxonomy: The full synonyms cross walk can be viewed here.
Assigning the State and County to each occurrence
When latitude and longitude data was used to assign the state/country when possible. If no latitude and longitude data was provided, the state and county names were pulled from the attribute data associated with the record. If a state or county name could not be assigned by either method the record was excluded from this analysis.
Flora of North America
If state level distribution information was provided for a given specific species, that information was used to filter the states in which counties are evaluated.
