Taxonomic Information on Cultivated Plants in GRIN-Global

Common Names

Presently, 64 190 common names for 21 396 taxa, including 32 648 common names of non-English origin, have been entered into GRIN-Global. To avoid the necessity of treating the multiple variations of a common name that can arise from differences in spelling, word union, or hyphenation (e.g., sugar beet, sugar-beet, or sugarbeet), we have attempted to standardize treatment of common names in GRIN-Global by adopting the conventions of Kartesz and Thieret (1991) on matters of union or hyphenation of group names and modifiers. Further decisions on joining or separating the elements of common names follow usage in Webster's Third New International Dictionary (Gove et al., 1961). These rules dictate that group names are correctly applied only to certain genera (such as rose for Rosa or vetch for Vicia) or families (e.g., grass for Poaceae). Some 618 "true group" names are provided in GRIN-Global for genera. Usage of these true group names for plants in other genera or families requires hyphenation or adjoining to preceding modifiers (such as moss-rose for Portulaca grandiflora or milk-vetch for Astragalus). General terms, such as tree, weed, or wort, that cannot be linked to any particular plant group always require adjoining or hyphenation. A few exceptions to allow usage of some true group names for more than one genus exist, such as pitcherplant for Nepenthes and Sarracenia, especially when genera have been recently dismembered, such as wheatgrass for Agropyron, Elymus, and Elytrigia.

Common names have been extracted from a variety of sources, such as floras, agronomic or horticultural works, or economic botany literature. Although some names appear in several sources, at least one source is presented in GRIN-Global for each common name. Sources are frequently indicated using GRIN-Global literature abbreviations, expansions of which can usually be found by consulting the references cited for that taxon. No effort has been made to include every locally used common name appearing in the literature; instead the focus has been to record those in wider usage. Some common names clearly in restricted use, such as those accompanying rare and endangered taxa, have been entered for reference purposes.

NGBT Plant Germplasm System Distribution Policy

Plant germplasm is distributed to scientists, educators, producers and other bona fide research and education entities from National genebank of Tunisia active collection sites. The NGBT Curator and/or Research Leader will, in accordance with current NPGS policies and procedures, determine the legitimacy of a request when necessary.

Distributions to fulfill requests for repatriation of subsamples of germplasm collections to a country or community of origin, especially following natural or man-made catastrophes, are considered a high priority.

Although distributions for research, education, and repatriation are of the highest priority, the NPGS also encourages various seed-saver organizations and public gardens to conduct germplasm conservation activities that engage many individuals and groups throughout the country. Elements of the NPGS cooperate with seed-saver organizations and public gardens and may store germplasm for and distribute germplasm to such organizations.

Distribution of germplasm from NPGS collections to fulfill requests from individuals seeking free germplasm strictly for home use is generally considered an inappropriate use of limited resources and conflicts with U.S. Government policy of not competing with commercial enterprises. Requestors can be asked, in an appropriate manner, to justify the use of specific NPGS germplasm instead of suitable commercially available germplasm.

Accessions listed in the Germplasm Resources Information Network (GRIN) database as “not available” due to insufficient or low viability seed and/or scheduled for regeneration will generally not be available for distribution.

Other accessions are listed in GRIN as “not available” because they are not a part of the NPGS collection per se, but are conserved in NPGS genebanks to meet specific needs as described later in the section entitled “Categories of Germplasm Distributed and Availability.” In this category are certain accessions of improved germplasm that are only available from the owner/developer. Other accessions require that specific conditions be met by the requestor before distribution is possible.

NPGS sites will not distribute germplasm internationally when they cannot comply with the importation or quarantine requirements of the recipient country unless the requestor can provide a valid waiver of such requirements.
