Worldwide Flowering Plant Family Identification Key (multi-entry key, Ray Phillips, Colby College)

Flora of the World (Christopher Davidson & Sharon Christoph)

      Images 'documenting all flowering plant families in their natural habitats, especially within biodiversity hotspots'

SPECIES AND FAMILY NAME INDEXES

International Code of Nomenclature for algae, fungi, & plants (ICN) (Melbourne Code, 2012)

International Code of Botanical Nomenclature (Vienna Code, 2006; superseded by Melbourne Code, but contains full Appendices)

      The legal code governing legitimate publication of a name or determination of the correct usage of a name.

Index Nominum Genericorum (ING)

      A compilation of genus names for Plants, Fungi, and Algae

Index Nominum Supragenericorum Plantarum Vascularium (J. Reveal)

International Plant Names Index (IPNI)

      The authoritative bibliographic source for all published names of Seed Plants, Ferns, and Lycophytes.

The Plant List, Kew

      This list aims to provide a complete account of scientifically accepted names and synonymy of vascular plants and bryophytes worldwide. It combines data from TROPICOS, IPNI and the Kew World Checklist of Selected Plant Families, but otherwise does not cite references.

TROPICOS, Missouri Botanical Garden

      Nomenclature database incomplete, focusing on areas of MO's active flora projects; however all synonymies are linked to literature references, which is tremendously useful! Caveat: For references which place a name in synonymy see tab "Accepted Names." For references which accept the name, see tab "References."

Taxonomic Name Resolution Service (TNRS)

       A useful tool for scanning lists of names for misspellings and commonly recognized synonyms.  Assignment of "Accepted Names" is based on an algorithmic mashup of Tropicos' incomplete literature-based synonymy data - but very useful for first order proofing. 

Concordance of Angiosperm Family Names

      Searchable index of flowering plant families, according to their treatment in several recent classification systems. By James Reveal / USDA.

"CAVEAT: IPNI, JSTOR Plant Science, TROPICOS and their ilk, were compiled by mortals, not the deity. . . . . these websites are starting points, not truths handed down from heaven." -- Christiane Anderson, in Guidelines for Preparing a Botanical Monograph.
