Lijst van auteursaanduidingen in de botanische nomenclatuur
Dit is een lijst met standaardaanduidingen, zoals die oorspronkelijk ontwikkeld zijn door Kew Gardens. Deze zijn bedoeld voor gebruik bij het citeren van botanische namen (wetenschappelijke namen die worden geregeld door de International Code of Botanical Nomenclature). Deze aanduidingen betreffen personen die ooit zijn aangeduid in de author citation van zo'n naam. Doorgaans wordt de standaardaanduiding in kleinkapitalen geschreven. Het gebruik van standaardaanduidingen is niet verplicht.

Enkele voorbeelden:
 Kickxia spuria  - eironde leeuwenbek
 Vicia faba  - tuinboon
 Passiflora loefgrenii 

De lijst is alfabetisch op auteursaanduiding (vaak een afkorting van de naam), inclusief initialen, exclusief leestekens. Dus  staat onder A en niet onder O.
