Taxonomic Information on Cultivated Plants in GRIN-Global




Literature References

For ease of computerization, 3,829 literature abbreviations have thus far been developed in GRIN-Global for standard references, floras, and serial publications commonly seen in the database. These are only cursorily displayed to public users of GRIN-Global, although for brevity they have been used in publications such as Technical Bulletins 1757 and 1796. They are employed for the 478,671 literature citations in GRIN that link to 65,576 accepted and 38,496 synonym species or infraspecies names. An additional 32,098 references exist in GRIN-Global for genera, these mainly documenting recent taxonomic revisions or monographs of all or part of a genus or recent phylogenetic studies. Though the number of references presented for a given taxon may be extensive, the listings should not be considered exhaustive. If all reported information (taxonomy, nomenclature, distribution, etc.) is documented in a few references, these might be the only ones cited. Other references may treat the taxon, but add no new information, so these may not be entered in GRIN-Global. This is particularly true for genera with recent comprehensive monographic treatments that are the source of most GRIN-Global taxonomic data for those genera. Other references may be included only to document alternative taxonomic treatments, orthographies, or authorship for a name. Generally these alternatives will be indicated with comments following the reference citation. The absence of a comment can usually be taken to imply correspondence in treatment between GRIN-Global Taxonomy and the particular reference.





The NPGS distributes plant germplasm to professional scientific research individuals and organizations, and verified plant breeders. Requests from producers and educators will be considered on a case-by-case basis, but only when NPGS germplasm that is not readily available from commercial sources is a justified requirement. NPGS germplasm is not available for individual, home, or community gardening. Requests to support educational objectives are typically considered only for college-level projects. Please view the short video on the NPGS for more details.
