The new website for the International Plant Names Index (IPNI) provides more dynamic searches, downloads and many other new features. Not all features are finalized yet, some of the wildcard searches are still being improved and history will be added later this year. Due to technical difficulties, daily updates are currently only complete until 29th March 2019. The IPNI team hope to resume daily comprehensive updates shortly.
Welcome to the International Plant Names Index (IPNI) 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.
