Nomenclatural Sources of the Northern Ontario Vascular Plant Checklist


The names listed in synonym in this database include both taxonomic synonyms and nomenclatural synonyms. It should be noted that no one source contains all of the species and synonyms listed in this checklist. Also, the accuracy of the synonymy included here is only as accurate as the information provided by the source.

Family names for flowering plants follow those ascribed to by the Angiosperm Phylogeny Group. Family names for ferns, fern allies, and gymnosperms follow those used in Flora North America, Volume 2 (Pteridophytes and Gymnosperms (FNA 1993).

The accepted species names and synonym in this checklist have been compiled through searches of several nomenclatural databases and taxonomic publications. Nomenclature used in the Flora of North America (FNA 1993+) series, considered to be the North American standard, has been used where available; future changes to this checklist will follow subsequent volumes as they are published. For species not treated yet in FNA, several online databases were used, primarily Missouri Botanical Garden's W3-Tropicos Database, the USDA's Germplasm Resources Information Network (GRIN) Database, and the International Plant Name Index (IPNI), which includes the Gray Herbarium Index (GHI). Names were checked in each of these sources, since some author citations were not complete in all databases. For example, the IPNI database does not always list the parenthetical author (the author of the basionym). Cross-referencing with GRIN and W3-Tropicos was therefore necessary to assure that scientific names and authorities were accurate. For introduced species, the GRIN database was most useful, as was the Index Synonymique de la Flore de France (Michel Kerguélen 1999), which contained very detailed and accurate taxonomic information for species of European origin included in our flora.

Other references frequently consulted included the Flora of Canada (Scoggan 1978) and the Synthesis of the North American Flora (J. Kartesz 1999), both of which were very useful in check geographic distributions and the presence of regional infraspecific taxa. A list of all references used in the compilation of this checklist and database is provided in the bibliography link.

When a discrepancy in author citations was found in 2 or more databases, a request for clarification was made to the taxonomic authorities for those databases, or to the original author of the taxon in question. The Northern Ontario Plant Database is most indebted to the following taxonomists, who shared information on specific treatments or checked the primary literature to solve many nomenclatural problems:

Dr. Ihsan Al-Shehbaz (Missouri Botanical Garden), Dr. George Argus (FNA), Dr. Richard Bateman (British Museum), Dr. Mary Barkworth (Utah State Univ.), Dr. Luc Brouillet (Univ. de Montréal), Dr. Kenton Chambers (Oregon State), Dr. William Crins (OMNR), Dr. Gerrit Davidse (Missouri Botanical Garden), Dr. Kanchi Gandhi (Harvard Univ. Herbarium), Dr. Stuart Hay (Univ. de Montréal), Dr. Allan Legge (Biosphere Solutions, Calgary, AB), Dr. John Morton (Univ. of Waterloo), Michael Oldham (OMNR-NHIC), Dr. John L. Strother (Berkely), Dr. Jim Solomon (MBG W3-Tropicos), Dr. Robert Soreng (US National Herbarium, Smithsonian Institute), John Valleau (Valleybrook Gardens, Niagara-on-the-Lake), Dr. Joan Venn (Univ. of Waterloo), Freek Vrugtman (Royal Botanical Gardens, Hamilton, Ont.), Dr. John Wiersema (USDA-GRIN).
