The International Plant Names Index (IPNI) includes information from the ''[[Index Kewensis]]'', a project which began in the 19th century to provide an "Index to the Names and Authorities of all known flowering plants and their countries".<ref name=Jackson1893>{{cite book |contribution=Preface |contribution-url=https://www.biodiversitylibrary.org/item/133989#page/10/mode/1up |contributor-last=Hooker |contributor-first=Joseph Dalton |contributor-link=Joseph Dalton Hooker |last=Jackson |first=Benjamin Daydon |title=Index Kewensis plantarum phanerogamarum: nomina et synonym omnium generum et specierum a linnaeo usque as annum MDCCLXXXV complectans nomine recepro auctore patria unicuique planta subjectis: sumptibus beati Caroli Roberti Darwin ductu et consilio Josephi D.

It is a nomenclatural listing of all published taxonomic plant names including new species, new combinations and new names at rank of [[Family (biology)|botanical family]] down to infraspecific. It provides data for other related projects including [[Tropicos]] and the Global Biodiversity Information Facility ([[GBIF]]).<ref name= TurnerGovaerts2019/>
