A binational collaboration of over 800 botanists and 30 institutions in the US and Canada, the FNA project is producing "a comprehensive set of taxonomic treatments for all North American plant species and infraspecific taxa" to be published online and in 30 printed volumes by Oxford University Press. FNA treatments include "accepted names, synonyms, bibliographic references, keys for identification, descriptions, economic uses, conservation status, weed status, and distribution data." Although the project and the site are still in development, users may access the text of four volumes via the FNA Portal. Readers will most likely want to begin with Volume One, regarded by the site authors as an important reference work in its own right. It contains a series of essays summarizing current knowledge on "the physical and biological factors that have affected the evolution and distribution of the plant life of North America" and the development of human understanding of the flora. Additional volumes discuss Gymnosperms and Pteridophytes, Magnoliidae and Hamamelidae, and Alismatidae, Arecidae, Commelinidae, and Zingiberidae. In addition to the taxonomic treatments, the volumes contain distribution maps, keys, illustrations, and graphics. The FNA Portal also features a keyword search engine that accesses the FNA document database, other online flora projects, botanical databases, and botanical libraries. Notes on Treatments-in-Progress inform visitors about planned additions to the site. A Species List and Bibliography are planned for the near future.
