With more than 4,000 kinds of native and non-native ferns and fern allies, nonflowering seed plants, and flowering seed plants, Florida has the third largest plant diversity of any state in the nation. Due to Florida's mild climate, many non-native species - including major pest species - readily become naturalized, contributing nearly one-third of the species of known flora. Some of the plant species found in Florida, many of which are endangered, exist nowhere else in the world.

Richard Wunderlin and Bruce Hansen provide a means to identify this vast array of plants with the only comprehensive identification manual and definitive guide to Florida's flora. These second and third volumes include taxonomic keys to family, genus, and species, with families arranged alphabetically for easy reference. Entries include the current accepted scientific name of each species, the major nomenclatural synonyms, many common names, general habitat preferences, and, for plants not native to Florida, the place of origin. The complete Flora of Florida volumes will be the standard reference for years to come.
