The International Plant Names Index (IPNI) is a database of plant names and their associated information. It is a collaborative project between several institutions and organizations, including the Royal Botanic Gardens, Kew, the Harvard University Herbaria, and the Australian National Herbarium. The IPNI provides information on the scientific names and synonyms of plants, as well as their authors and publication details. It also includes information on plant families and higher taxonomic groups. The IPNI is considered a valuable resource for botanists, horticulturists, and anyone interested in plant names and classification. It is freely available online and can be searched by plant name, author, or publication. The IPNI is regularly updated to ensure the accuracy and completeness of the information it contains.
