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.
