Authoritative taxonomic and distribution databases

These databases are useful for confirming accepted names, synonyms, and geographic range. For best results, search by scientific name (e.g., Monarda punctata) and verify the authority and synonym history when available.

USDA PLANTS Database (United States)
A practical reference for accepted names and U.S. distribution summaries.
Open

POWO — Plants of the World Online (Kew)
A global taxonomic reference maintained by Royal Botanic Gardens, Kew.
Open

World Flora Online
Global species information and taxonomy reference project.
Open

GBIF — Global Biodiversity Information Facility
Aggregated occurrence records useful for broad distribution patterns.
Open

ITIS — Integrated Taxonomic Information System
A cross-agency taxonomic database commonly used for name verification.

Regional native plant references

Regional databases often provide habitat notes, morphology summaries, and interpretive descriptions that complement global taxonomic databases. These can be useful for field identification and habitat context.

Lady Bird Johnson Wildflower Center — Native Plant Database
Habitat notes, plant descriptions, and regional context for many U.S. native plants.
Open

USF Atlas of Florida Plants
Example of a high-quality state-level atlas with distribution and taxonomy notes.
Open

BONAP — Biota of North America Program
Distribution-focused maps for North American plants (useful for quick range checks).
Open

NatureServe Explorer
Conservation and occurrence summaries; useful for status and range context.

Herbarium and specimen resources

Herbarium resources are useful for seeing verified specimens, comparing morphology, and understanding how a species is documented across regions. Specimen images can be especially helpful when cross-checking bract structure and floral arrangement in Monarda.

iDigBio
A major U.S. aggregator of museum and herbarium specimen records.
Open

JSTOR Global Plants
Digitized plant specimens and type material (access may vary).
Open

Consortium of Northeastern Herbaria (example consortium)
Regional specimen portal with verified records and images.
Open

SEINet (Southwest Environmental Information Network)
Regional specimen portal covering large portions of the U.S. (varies by consortium).
Open

Observation platforms (use with caution)

Community observation platforms can be useful for field photo comparison and seasonality, but identifications are not always correct. These resources are best used as visual supplements, not as final authorities.

iNaturalist
Observation photos and community identifications; verify with taxonomic references.
Open

BugGuide (pollinator context and plant-adjacent observations)
Not a plant database, but useful for pollinator-season context in some cases.
Open

How to verify a name responsibly

A conservative workflow is to (1) confirm the accepted scientific name in a major taxonomic database, (2) check synonym history where available, (3) confirm distribution with at least one occurrence-mapping resource, and (4) compare morphology against herbarium specimens or a reputable flora description.

When a historical source uses only a common name, species-level certainty is often not possible without additional contextual detail. In these cases, genus-level interpretation is usually more defensible than forcing a modern name onto an older label.
