The Index Nominum Genericorum is a collaborative project of the International Association for Plant Taxonomy (IAPT) and the Smithsonian Institution. ING was formed to bring all generic names of plants together in a single list, revealing homonymy between groups. This searchable database includes bibliographic citations, as well as information about the "typification and nomenclatural status" of generic names. For researchers or students of taxonomic botany, this site provides a useful, though highly specific, service. Note that the on-line version of ING will be modified to reflect new listings and taxonomic changes.
