Authors of Plant Names database (APN) is a world list of authors of scientific plant names with the recommended standard forms of the authors' names, including abbreviations, derived from a single-volume reference book.

Note: The APN and IK(ew) databases are also now available on the web at www.us.ipni.org, or www.ipni.org (International plant names index website) but faster searching can be done using locally mounted IKew/APN.
