The "Scientific Name-String" represents a scientific biological name. The generation of scientific names is governed by codes of nomenclature, including: The International Code of Zoological Nomenclature The International Code of Nomenclature for algae, fungi, and plants The International Code of Nomenclature for Cultivated Plants The International Code of Nomenclature of Prokaryotes The International Code of Virus Classification and Nomenclature However, these codes do not provide universal, strict rules on how names must be spelled out. As a result, a scientific name can be represented by various name-strings. Examples of different representations for "Carex scirpoidea var. convoluta" are: Carex scirpoidea var. convoluta Carex scirpoidea var. convoluta Kük. Carex scirpoidea Michx. var. convoluta Kükenth. Carex scirpoidea var. convoluta Kükenthal It's important to note that the code for viruses does not follow binomial nomenclature. This endpoint resolves a specific spelling of a scientific name to data-source records where that name-string was used. Appending the URL with the name-string GlobalNames identifier, or the string itself will provide more details of the "best match". It is also possible to expand search to all relevant results, and filter out results to particular data-sources by providing their IDs.
