International Plant Names Index
The International Plant Names Index (IPNI) is a database of botanical names for seed plants and ferns . It was created in cooperation with Royal Botanic Gardens Kew (" Index Kewensis "), Harvard University Herbaria ( Gray Herbarium Card Index) and Australian National Herbarium (APNI). The standard for the author's abbreviations is based on the recommendations of the International Code of Botanical Nomenclature and goes back to the standard work of the botanical nomenclature Authors of Plant Names published in 1992 by the British botanists Richard Kenneth Brummitt and C. Emma Powell . The database has been kept at the Royal Botanic Gardens in Kew since 1998.
