Due to technical issues with the IPNI database, we have made the new IPNI website live. The data on the site is current through April 2019. We are aiming to restore regular updates as soon as possible.
Welcome to the Beta Test version of the new website for the International Plant Names Index (IPNI). We provide nomenclatural (spelling, author, types and first place and date of publication) information 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 we are continuously working to improve data standardization.
