Search the Data
The International Plant Names Index (IPNI) is a database of the names
and associated basic bibliographical details of seed plants, ferns and lycophytes. Its goal 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 a dynamic resource, depending on direct contributions
by all members of the botanical community.
IPNI is the product of a collaboration between The Royal
Botanic Gardens, Kew, The Harvard
University Herbaria, and the
Australian National Herbarium.
Melbourne Code available online.
From 1 January 2012 electronic material published online in Portable Document Format (PDF) with an International Standard Serial Number (ISSN) or an International Standard Book Number (ISBN) constitutes effective publication.
We want to make sure that IPNI captures all relevant nomenclatural novelties, whether published online or in printed form.
IPNI users can help. Let us know if you publish or find names in an online publication by sending us a link to the relevant site.
To help you to quickly find information on authors, many new links have been created from author records to TL-2 page in BHL. Try it out. Click on the link in this record.
Some records now have a link to the protologue page in BHL. See an example here.
Missing protologues - can you help us find some of these?
IMPORTANT: IPNI does not have information on what are currently accepted names and what are taxonomic (i.e. heterotypic) synonyms. Find this information in floras, monographs, checklists, revisions etc.
See new names just added by searching by additional terms. Search must be limited by at least one term, like family, genus or author.
