Lists of plants can now be produced easily, accurately and comprehensively for any geographic area from private farms or private woodlots, to small towns or large cities; from National Parks, and National Seashores to U.S. states and Canadian provinces. Even for home-sites with personal mailing address or for local school grounds, or for areas with specific longitude and latitude coordinates, lists of plants can be generated with ease and precision. In order to achieve this accomplishment, BONAP incorporated tens of thousands of plant lists from small florulas throughout North America into larger floristic units, then linked these data with U.S. postal zip codes, and then to FIPS (Federal Information Processing Standards) codes, then to longitude and latitude coordinates, and finally to all of the North American place names on Google map. By using Google map as our search engine, we were able to produce the Floristic Gazetteer. Moreover, by using expanding concentric quadrangles, we were then able to expand the floristic coverage of any location outward by 10 - 20 or more miles, thus increasing the number of potential species found within adjacent locations. To facilitate the entire process, an embedded spell-checker was used to correct automatically typographical errors of locations without altering results. Although the system currently treats only members of National Wetland Flora (approximately half of the North American flora), we plan to include the entire North American flora later this year. The Floristic Gazetteer can be found within the Geographic Query window (Place Name or Zip code under Select Geo Type) on our North American Digital Flora.

The potential for this release is limitless. Consider for example, the inclusion of an interactive key that collapses to adjust for only those species found within a specific area. This process would facilitate greatly the task of identifying unknown member of the local flora. It would certainly ease the effort of keying by reducing the number of species found within any location. In testing the accuracy of the Floristic Gazetteer, we found that even in poorly collected areas, species diversity tallies can be made surprisingly complete by using the concentric quadrangle to expand the search into adjacent locations.
