International Plant Names Index

A database of the names and associated basic bibliographical details of all seed plants. Its goal is to eliminate the need for repeated reference to primary sources for basic bibliographic information about plant names. The data in the IPNI comes from three sources: the Index Kewensis (IK), the Gray Card Index (GCI) and the Australian Plant Names Index (APNI).The data are freely available.
