This is a list of botanists who have Wikipedia articles, in alphabetical order by surname. The List of botanists by author abbreviation is mostly a list of plant taxonomists because an author receives a standard abbreviation only when that author originates a new plant name.
Botany is one of the few sciences which has had, since the Middle Ages, substantial participation by women.Script error: No such module "Unsubst".
