Database of the names and associated basic bibliographical details of all seed plants, ferns and fern allies.
The goal of IPNI is to eliminate the need for repeated reference to primary sources for basic bibliographic information about plant names. The data are freely available and are gradually being standardized and checked. IPNI is produced by a collaboration between The Royal Botanic Gardens, Kew, The Harvard University Herbaria, and The Australian National Herbarium, hosted by the Royal Botanic Gardens, Kew. IPNI provides nomenclatural information (spelling, author, types and first place and date of publication) for the scientific names of Vascular Plants from Family down to infraspecific ranks. You can search for plant names, authors or publications in the search box above. Click the down arrow for advanced search options. New records are added daily, and the IPNI team are continuously working to improve data standardization.
One part of the database is the Index Kewensis (IK). It is maintained by the Royal Botanic Gardens, Kew and its aim was to register all formal botanical names for seed plants, at the rank of species and genus. Later, it also started to include names of families and of taxa below the rank of species. It was started in 1885, with regular supplements issued on newly published names. A digitized version of the IK has been integrated in IPNI so that it can be consulted online: its entries are recognizable by the letters "(IK)".
