Provided by the Biota of North America Program (BONAP) in collaboration with the Texas A&M Bioinformatics Working Group (TAMU-BWG), The BONAP Synonymized Checklist is more than a typical checklist. It is a database, offering multiple layers of vascular flora information at several different taxonomic levels. Understanding the organization of the site is central to its utility; to enter the database, users may select options to browse by family name, query by genera or common name, query text (for text strings), or follow links to the Flowering Plant Family Finder (Cronquist classification system; also accessible through The Flowering Plant Gateway, reviewed in the September 25, 1998 Scout Report). Once inside the database, users can drill down to distribution maps of the selected family, genus, or species. In many cases, species images accompany distribution maps through links to the Vascular Plant Image Gallery (reviewed in the September 12, 1997 Scout Report. This new resource unifies and deepens the already impressive wealth of TAMU-BWG/BONAP information on vascular flora on the Web.
