Taxonomic Name Resolution Service (TNRS)

The iPlant Taxonomic Name Resolution Service (TNRS) can help correcting and homogenizing list of plant scientific names. It allows input as text lists or files. It can check the names against the databases of TROPICOS, GCC, USDA and NCBI. It’s available through a web interface and also through web services.

The Taxonomic Name Resolution Service (TNRS) can resolve many forms of taxonomic semantic heterogeneity, correct spelling errors and eliminate spurious names. As a result, the TNRS can aid the integration of disparate biological datasets. Although the TNRS was developed to aid in standardizing plant names, its underlying algorithms and design can be extended to all organisms and nomenclatural codes. The TNRS is accessible via a web interface at and as a RESTful web service and application programming interface. Source code is available at
