derives from the Latin word for ''of authors'', and is abbreviated auct. or auctt. Some species names have been used twice for different species so the author of the name needs to be identified. For example "''Leucospermum bolusii'' auct. Gandoger" for the species that was named as such by Gandoger. It is often used in conjunction with nec or non to indicate a misapplied name, e.g. "''Leucospermum bolusii'' auct. non Gandoger" would mean the species not named by Gandoger. It may be qualified to indicate the number of authors, e.g. auctorum multorum (abbreviated auct. mult.), Latin for ''of many authors'', indicating that many subsequent authors used a name in a different sense to the original author, and also by non to give auctorum non (auct. non), to indicate that a following author is not the author of the species.
