A name and a date after a species.
Also known as: Author citation taxonomy, Binomial authority
The convention appending the describer's name and year to a scientific name, with brackets carrying a rule.
Names the author who first described a species and the year of that description.
Contexts: History, Laboratory
The brackets are not decoration: their presence states that the species has been moved out of the genus it was originally described in, so a bracket records a taxonomic history in one character.
Contexts: History, Laboratory
Botanical and zoological codes apply the bracket rule differently, so the same punctuation carries different information in the two disciplines.
The botanical and zoological codes differ in their use of parentheses in authority citations.
Contexts: History, Laboratory
A personal name and a year set after the species name, enclosed in round brackets when the species has since been moved to another genus.
