Authors of Plant Names (Brummitt & Powell) by Richard Kenneth Brummitt and C. Emma Powell, 1992, is a print database of accepted standardized abbreviations used for citing the author who validly published the name of a taxon.
[1][3] Prior to its publication in 1992, many abbreviations for authors to be cited could be found in Taxonomic literature.
A selective guide to botanical publications and collections with dates, commentaries and types.
[4] The International Code of Nomenclature for algae, fungi, and plants (ICN) governs the naming of these organisms, and suggests that a taxon be fully identified by its name and the author, but does not require that abbreviations be used when citing an author for a taxon.
[5] Brummitt & Powell may not be international in scope, and it may be missing abbreviations for authors who validly published taxa during some time spans.
